Advertising agencies are going through an interesting little adjustment right now. At least the bigger ones with national clients who are flocking back to trade shows. They're are moving from aiming all their stuff at the web to the opposite extreme: Posts and huge trade show graphics. The two common denominators are a need for lots and lots of resolution and also the need for content to be sharp. Unlike billboards posters, point of sale materials and trade show walls are all media that consumers can get right next to and put their noses on.
The top image is on of a hand full I sent to the agency. At full size it's a 215 Megabyte tiff file. The Image just below is a close up of my left eye. Seems to blow up pretty well.
The agency is mollified and we are continuing in our conversations....
Have a sharp day.
