My continuing love affair.......with the Canon 7D. Enhanced by the 60mm efs and a few LED lights

I'm taking a risk today.  I'm posting from my laptop and the screen isn't nearly as well calibrated as the monitor in my office.  I'll assume this looks like my model, Selena, and that the flesh tones are somewhere in the ballpark.  Apologies if it's bright purple.....

I don't have a scientific method of measuring the different ways in which various cameras handle color, I just know what colors I like to see and always how I like the contrast of the files rendered.  Now I'll head into heretical territory.  I recently did a big job for an ad agency.  24 portraits in two days.  On site.  I used two cameras.  My main camera was a Canon 5Dmk2 with a 100mm f2 lens tacked onto the front.  The other camera was my old Kodak DSLR/n with an even older Nikon 135mm f2.8 on the business end.  The exercise went like this:  Shoot the bulk of the frames with the Canon camera and, when I felt like I had what I wanted, pull up the Kodak and shoot an additional ten frames.  All the frames were shot under the same lights,  Profoto monolights in the 600 w/s and 300 w/s varieties.  I used a gray Lastolite target and did a custom white balance for each of the cameras.  I shot both of them in RAW.  I processed both sets of files in Lightroom 3.0

And what to my wondering eyes did appear?  Softer, smoother, more accurate tonalities and colors out of the Kodak camera.  Much easier to post process into pleasing files.  And whether it was a different "shoulder/toe" curve parameter or just more dynamic range, the Kodak beat the snot out of the Canon 5d2 in terms of holding juicy detail in slight overexposures.  Now, if I really dig in and spend the time I can get the two cameras to look a lot a like but when I show the files as 12 by 18 inch prints my art director friends choose the Kodak prints every time.  Every time.  The Kodak came onto the market in 2004.  In camera years that's like a decade ago.  The Canon is barely 18 months old.  Amazing.

In it's defense the Canon 5d2 has great detail and for most things, very decent color.  But it was enough to shake my nascent confidence in Canon's supposed supremacy as a portrait camera.  So I was expecting the 7D from Canon to be no great shakes.  But I was wrong.  When I go thru the same process and do the same white balances with the 7D it creates files that, while not quite as detailed as the 5d2, are much more pleasing in the eyes of this portrait photographer.  And I'm still trying to figure out why that is.  It's a newer sensor but not by much.  They have the same Digic 4 processors.  And the lenses are the same.  But I guess it's one of those things I'll never have a solid metric for because I'm pretty sure the guys at Canon don't want to get into a dissing war between their various cameras.

Suffice it to say that I started shooting with the 7D more and more.  That moved me to buy an interesting lens, against my better judgement.  It's the 60mm macro, EFS.  EFS means that it only covers the optical circle of the Canon cropped frame cameras.  Won't even fit on the front of a 5D2.  But it just seemed like the perfect portrait focal length for the 7D and other cropped sensor cameras.  It's nice and small and fits on the body well.  Not too front heavy.  And it opens up to 2.8.  Here's a photo sample from last week:
It's shot at 3.2 and some slow shutter speed but it looks good and handles well.  The combination works for a lot of the faster, candid portraits I sometimes do and it doubles as a macro rig when I need to get close.  The other two shots in this blog were done with the 70-200mm f2 (non-IS) which I mentioned recently.  It's an incredibly good lens and, if someone handed me $2400 and asked me to buy myself another long zoom I'd pass right by the new 2.8 type two, snap up another $600 f4 and stick the rest into something else.

In a previous review I wrote at length about the handling of the 7D and the responsiveness of the auto focus but my recent romance with LED panels has caused me to think more about the color handling characteristics of various camera models instead of the more common threads of discussion which tend to center around resolution and dynamic range.  I've found that both the 7D and the new 60D are much better in AWB than any other Canon camera I've had the chance to handle.  Much better.  And when I'm in the studio shooting under the non-continuous spectrum of my wacky LED lights I find that the cameras, when left to their own devices, hit the proper white balance right off the mark, unlike the 5d2.  If you throw the Kodak I mentioned into the ring you'd have the opposite of the AWB Bell Curve.  In the absence of a custom white balance shooting with the Kodak is like shooting thru a kaleidoscope.


So I did a little reading to see what I could find out.  Here's the factoid that I'm hanging on to:  Both the 7D and the 60D make use of Canon's Intelligent Focus Color Luminosity metering system.  It's part of the autofocus system but it uses color sensors to more effectively understand what's in the  frame.  It's only a suspicion on my part but I believe that this new measurement tool is also somehow tied into the overall camera white balance tools and this gives the newer cameras an edge over the other cameras in the system that don't share this technology.


Let's talk about flash for a moment.  I know a lot of wedding photographers swear by their 5dmk2's and I can understand why.  It's a good camera with a sensor that's capable of capturing a lot of detail.  But when it comes to flash and autofocus in dimly lit venues I can't see why these photographers don't rush to pull the 7D out of their bags.  The flash performance is a full generation ahead of the 5d2.  The autofocus lock on is two generations better and probably on par with the system in the 1Dmk4.  The flash makes use of the same IFCL metering system that I talked about above and in combination with the flash exposure lock button flash becomes as easy as shooting Nikon.


I put the camera and 580 ex2 flash thru their paces in the dimly lit ballroom at the Four Seasons Hotel last thurs. night.  Legendary attorney, Joe Jamail, took the podium in a crowded ballroom to give a speech about UT's president, Dr. Bill Powers.  Before he launched into his speech he squinted at the spotllights illuminating the small stage and asked, "Can you turn those darned things down?"  They did.  And it dropped the overall illumination a lot.  Even though Mr. Jamail was in a dark suit and the stage was backed with black curtains the camera/flash combination did a great job nailing the exposure using the FEL spot pre-metering and locking in the settings.  I try to take only a few flash shots because, no matter how discreet you try to be, it still gets annoying.  I switch over to a preset custom banks which changes my settings to 2800 K color temperature, ISO 3200, spot metering and "Camera Neutral" color setting.  And I will say that, with a little noise reduction edged in, the camera performs quite well at what would have been extreme nose bleed territory for a cropped frame camera only a year ago.......


So where does this new found appreciation put me in terms of grabbing cameras for assignment?  Well, if resolution, sharpness and final reproduction size are all critical my choice will be the 5D2, hands down.  If I have to get the tiniest slice of focus and put everything else out of focus I'll also grab for the same camera.  But if I can shoot under 1600 ISO, need fast AF, need good out of camera color balance and good white balance, and if handling is critical it's the 7D all the way.  With my 20,  my new 35 f2 and the 60mm macro EFS I've got a nice, small and light "classic" photojournalist's set up that doesn't break the bank.  Throw in a couple of wide ranging zooms like the 15-85 and the 70-200 f4 and a 60D as a back up body and I have system I'd feel comfortable with on a very large portion of my jobs.


Thank the photo dieties,  they all take the same batteries.  Just a few random observations from a week of daily shooting....


Lit with a single LED panel blasted (ha, ha) through a Chimera diffusion scrim.









the holidays are upon us.  I humbly submit that a good book about photography will be most welcome by the photographers on your list.  Here are a few suggestions:

The Canon 60D revisited. Funny what a lens will do.....

 I liked the 60D the minute I picked it up and (with a few caveats) I've liked it more and more as I've used it.  But it wasn't until I capriciously stuck the Carl Zeiss 50mm 1.4 ZE lens on the front of it that it became my favorite camera to take out shooting.  It's more responsive and feels about one and half generations better than a Canon 5Dmk2.  It's at least as good a camera for most non-ultra-sport shooting as the Canon 7D.  And I like the way it feels in my hands.

I originally bought the 50 Zeiss to use on the 5D2.  I thought it would create very cool looking images with impressive DOF effects and it did that just fine.  But what it didn't do well was manually focus.  And when I used the focus indicator or the focus indicator+obnoxious beep I found that the combination missed the point of sharp focus, no matter how I had the camera set.  The 7D was a bit more accurate but even with the micro adjust feature of both the more expensive cameras I was never quite sure I'd get what I wanted in sharp focus.  Which led me to believe that the mis-focus anomaly must either be non-linear or intermittent.

On a whim I put the lens onto the 60D and set the menu items for "stupid operator in need of much help" or SOINOMH mode.  That means, center focus point, beeping confirmation and steady green light indicator hand holding.  I proceeded to shoot and the oddest thing happened:  Every time the camera told me I was in focus I really was in focus.  I was soon able to lose one set of training wheels.  The beep.

Although I leave the beep on if I'm around a bunch of really pretentious gear nerds because it seems to drive them crazy and, as they flinch and clutch at their 1DS mk3's, I have a moment of selfish entertainment......)

A benefit of this newly realized focusing capability is the new knowledge that the Zeiss lens is sharper wide open than I originally thought and the saturation and color rendering is pretty darn good.  This leads me to leave that lens on that body all of the time.  This combo gives me a solid platform, great images, smaller form factor and the satisfaction of having a tool combination that's working at optimum efficiency.  If you don't shoot sports and you don't need the full frame chops of the 5Dv2 this is really a wonderful little camera with good high ISO performance into the bargain.  I grab it first when I leave the house or studio.  When I'm being reckless this is the combo I keep in the car.

But I'm not writing this with the intention of slagging the 5 or the 7.  It's just that this whole circus of lens  madness and focus brought me to realize that there may be an optimum lens and camera combination for each body.  I spent a while looking through images I've taken and I think it really breaks down like this:

1.  The 60D and the Carl Zeiss 50mm is my favorite combination for casual portraits and walking around  just making photographic trouble.  I like shooting with the rig between f2.2 and f3.5.  I like what it does to the backgrounds when I get in close.  Works for me.

2.  The 7D is the perfect match for the 15-85 and that combination is rarely rent asunder.  For some reason I feel like they ultimately compliment each other.  I love the wide angle end and I find more and more that it's a lens that was made for wide open shooting.  The 7D sensor and AF seem to wring out every scintilla of performance from the optics and vice versa.  If it's commercial and I've got to get the shot this is the camera I'll grab.  Doubly so if it involves "smart flash" or HS flash.  Really.  Almost as good as the Nikons........sniff......(meaning as good with flash as the Nikons are.  Not anything else.)

3.  The crazy anomaly.  The 5D2 has the best overall image quality of the three and not just by a whisper.  But it seems harder to extract that extra five to ten percent of quality for me.  Sometimes, when all the stars line up I get incredible stuff.  And for high ISO I am consistently impressed and amazed.  But it can be a goofy camera to work with.  The body doesn't really feel as solid as the other two.   And instead of one there are two lenses that I think are synergistic with it.  One is the 85mm 1.8 which seems to ride on the body about 60% of the time.  The other is the 70-200 f4 which comes out of the case when we do traditional portraits, lit with softboxes and perfectly metered.  Every frame is sharp from f4 on down and it has no weird CA's or soft spots.  I thought I'd love the Canon 5D2 with the 50mm focal length but that's been a non-starter for me.  I love using it on a tripod and with the mirror locked up.  That's "sharp mode" and it really reaches down and pulls out great performances when used that way.

If I had to choose one of the three to go and shoot personal work with?  It'd be the 60D.  More to come.

I was thinking about this whole subject as I was "nerding" around in the studio getting used to my new LED light fixation.  I decided to do a photograph with which to illustrate this blog and I wanted to see how the new lights would do on a product shot.  I wanted to see what, if any, the advantages of using LED's over florescent or hot lights would be.

Right off the bat I found that I could use the lights closer than I every have before.  That means even a small panel with some diffusion on it yields the same soft light as other fixtures in bigger fixtures used further away.  I could also use fixtures right next to my camera without worrying about being blinded by the flash or heating up the camera.  In the same situation the florescents would probably have held their own.  But compared to tungsten and flash the whole setup, visualization process and shooting was easier, more comfortable and more straightforward.

I even included a set up shot.....just for fun.

not shown is one more light to the far left of the scene which is providing additional illumination on the background to keep it even.


The lights are the ePhotoinc LED 500's I've mentioned before.  I took a chance and it turned out well.  So far I've done a handful of assignments and my only real issue is that getting perfect white balance has to be more intentional at the front end of the process now.  Also, the lights can cause polyester fabrics to go a bit purple.  I'll experiment with some UV filtration when I get back by gear.   For everything else?  Charming.  And cool.

Small Flashes on Location. Again.

     Dr. White on location at his office in Austin.


I've been doing a series of ads for a large oral surgery practice here in Austin.  We are introducing the partners/doctors to the community in a casual ads that showcase the doctors engaged in their hobbies.  We photographed a rancher/doctor feeding a baby dear with a bottle in a pasture.  We photographed one person with his Ducati Monster motorcycle out on the golf course and we photographed one subject with his horse.  All the shots were fun and showed a side of the guys that people rarely see.  It served to make them more than two dimensional.

But then I came along a doctor who had sacrificed his free time to be the president of his professional association.  He was adamant that for the past two years any time he didn't spend practicing medicine he spent working for its improvement.  He felt most at home right in his office.  So that's where we did his photograph.

I am standing out in the hallway and Dr. White is sitting just inside the door.  I'm using a Canon 580 EX2 flash in a Speedlight Prokit beauty dish about two feet above camera, tilted down at him, for my main light.  Behind him and over to the left of the frame I'm using a second flash, a Vivitar 383 df, bouncing off the ceiling in the middle of the room.  I used a third flash, also a Vivitar 383 df from the back right of the room, with a home made grid attachment to provide just a little bit of accent light to the left side of his face to give a bit of separation with the back wall.

All of the lights were used in manual mode with the main light at 1/4 power, the room fill at 1/2 power and the accent at 1/8th power.  I used a Canon 7D body with a 15-85mm zoom lens set at f5.6.  The ISO setting was 200 and the shutter speed was 1/50th of a second.  The camera was on a Gitzo tripod.  I was looking for a realistic but flattering lighting design that didn't call too much attention to itself.

The shot was done in raw and processed in Lightroom 3.

From a technical point of view there is a big shift in how I pack to light things.  In the past I would have taken monolights or a strobe pack and heads but now it just feels natural to take small lights for indoor shots.  Nine times out of ten the big lights would require me to really throttle down their power in order to match them up with room light levels.  Then there's the hassle of running extension cords all over and the need to bring bigger stands and accessories.  When I go to shoot interiors now I'm generally feeling well equipped if I take one Canon flash, like the 580 EX 2, and three cheap manually controllable flashes for fill and accents.  All of this and the Speedlight Prokit beauty dish and a few other modifiers fit comfortable into a Think Tank wheeled case along with the camera and a few lenses.

I triggered the main light with a long Canon off camera TTL cord (the flash was used on "manual") and then let the two Vivitar 383's provide their own slave function with their built in optical slaves.

Obversely, when I go out to shoot on locations that are exterior I find that I generally leave the small flashes at home and use the more powerful Elinchrom Ranger RX pack system (1200 watt seconds) or the Profoto 600B pack system (600 watt seconds).  These lights provide me the punch I generally need to blow light through a softbox and still match sunlight.  I take the Profoto if I want to move fast and the the Elinchrom when I need a lot of pops.  (I also have an extra battery for the Elinchrom....).

Outside I use a radio trigger (Flash Waves 2) or an old fashion PC cable to trigger the flash.

I used the 7D on this assignment because I like the versatility of the 15-85mm lens and I like the fact that it's really very sharp wide open.  Couple that with better autofocus than the 5D2 and you've got a camera and lens package that's easy to shoot.  I was originally seduced by the full frame of the 5D camera but in practice I've come to appreciate the advantages of the cropped frame cameras and often choose the APS-C system of the 7D, backed up with a 60D for a lot of my work.

Doesn't matter what you're shooting with as long as you're having fun and making money.

Announcement:  I'm pleased to say that my first book: Minimalist Lighting.  Professional Techniques for Location Lighting,  is back in stock at Amazon after being sold out for several weeks.  Sigh of relief.

A fun video project. Kids are always fun to work with....

You can see it much bigger on Vimeo:  http://vimeo.com/15334802

Will van Overbeek and I were hired to do a video project last week.  Several organizations here in Austin were being awarded by The Austin Children in Nature Collaborative and the videos will be used as showcase introductions at a special program at the Austin Four Seasons Hotel.  We needed to make an introductory piece for the award program.  The only problems we had were:  No script, no actors, no direction and a lot of rain.  Since the program celebrates getting kids outdoors the rain was kind of a major issue.  The rest just go with the territory.

We made it to the Austin Nature Center just in time for the big rain.  But it let up after a while and we got to work.  For this project we used a Canon 7D with a 24-105mm L lens, a Rode Videomic and the Rode Stereomic,  a Gitzo tripod with a Manfrotto fluid head and a small, LED light (more about that later....).  For this project I operated the camera and Will did the sound.

I think we were all pretty amazed at how well the sound turned out.  The center is located near a major, elevated highway and there's random noise coming in from every direction.  Our method is to put the microphone on a "fish pole" and get it in as close to the speaker as possible without getting an image of the mic (or its shadow) in the final video.  We found the ALC (auto level control)  on the 7D does a pretty good job on its own.

Our biggest challenge was to get interviews with four and five year old kids.  They're not really good at hitting their marks and they don't "do" lines.  But with a smile on your face and a big enough memory card you're sure to get something.....then all you have to do is edit it all together.  I like sound effects but I don't think Will is as enthusiastic about them.  He did allow me to add a few "dinosaur roars", "chimpanzee chatters" and "jungle" noise from the sound library.  I think it's fun.

Since we're all about keeping things simple and fun we jumped right into editing this thing with iMovie 09 from Apple.  We used an old laptop and a calibrated, 23 inch Apple monitor to do our edit on.  We did add a firewire 800 outboard HD to the mix.  No stutters in the editing or the output.  The edit took about an hour and fifteen minutes this morning.

We did some interviews with grownups in order to get information across.

While we were waiting for the rain to stop we did an interview with the program director from the Center.  I was happy to have the new little LED light with me.  We needed a bit more light to brighten up our talent's face.  The light is called a DLC DL-DV60 and it's the perfect light to keep in a side pocket of your camera bag.  It uses 60 individual LEDs to provide a fairly small, bright source.  You won't be overpowering sunlight with it but it might be just what you need in a pinch for a little more punch.

I first played with a light like this one when I was writing my book, Photographic Lighting Equipment.
The one that was available at the time was a LitePanel Micro from LitePanels.  It was about the same size as my new DL-DV60 but it put out significantly less light.  It also sold for somewhere near $300.  The one feature that the LitePanels Micro had that I did like was the ability to turn the light down with a control knob.  It was also cool that the color temperature of the light didn't change as you turned down the power.  The DL-DV60 doesn't have any control other than on and off.  But here's the deal:  It's a little bit shy of $100.  The one "feature" it does have (and I'm still not sure if I like it...) is this:  it comes with a rechargable Li-ion camcorder battery for power.  It's a common Sony battery so replacements are widely available and it does have enough power to punch out light for about an hour and a half.

In the video we used the light about seven feet away from the program director and about three feet above her head.  It was enough to minimize shadows on her face and bring her a bit forward from the tungsten lit room.

I liked the DL-DV60 enough to buy a second one.  They can be clipped together to make little light banks and I think that's a fun thing to have in a pinch.  I've also order some bigger ePhoto panels that plug in the way and use hundreds of individual bulbs.  I'll let you know how those work when they arrive.

Will and I are starting to get into a groove with our little video projects.  It's different than still photography but in some ways the same.  Directing is always fraught with peril that mostly becomes obvious at editing time.......


This is the DL-DV60 as it sits on top of my camera.  It's too bright to aim directly at innocent people indoors without some sort of diffusion but it works well in conjunction with other light sources.  It also works well as an accent light in the same way you might use a flash on an off camera cord, over to one side.  The benefit is that you don't ever need to sync it with the camera.  It also doesn't get too hot and it doesn't flicker.  It's pretty perfect for a combination/crossover photographer/videographer.

More to come.

I'm accepting more and more video projects and finding that I like the process pretty well.  I try to stay away from clients who want to micro-manage projects.....it's almost a given that they will slow the editing process down to a crawl.  So far all of the clients have been perfect.  And the Canon cameras are working well.
