i have a buddy who is a graphic artist who is the same way....he's a REALLY GOOD graphic artist, and actually teaches design at a university, but he always talks in DPI, forgetting about pixels....he's used to dealing with vector files, which don't contain pixels at all, so he's always wrapped up in DPI....as a photographer, all i care about is pixels....
so yes, to the original poster, whether your file is 240dpi, 300dpi, 600dpi, or 72dpi, if you haven't cropped it from original, it still is approx 4200x2800....if you want it do be 300 dpi, and the image is printed...Show more →
He is NOT a "really good graphics artist", and a really bad teacher if he can't separate rasterized graphics and vector graphics - since they're the two base image representation functions that you should learn to separate to be allowed to pass the first semester of anything even remotely connected to "computerized graphics" at university levels. He's going to make a lot of people that will later work in the printing / pre-press / graphic artist sections really confused (and really wrong about a lot of things that will cost their employers money!) unless he's clear about this difference.
In fact, it's something that's considered base knowledge if you attend a highschool/college with graphical / artistical mains nowadays. Repeat ten times:
-"the resolution of a 4300x2800 raster image at 1dpi is 4300x2800 pixels. The resolution of a 4300x2800 raster image at 1 MILLION dpi is STILL 4300x2800 pixels. No more, no less. Ever. For eternity."
I've worked as the process development engineer at a printshop having a net turnaround at just over 100M USD per year, and this ws one of the things that we had to STOMP into the minds of all the pre-press personnel during the first years of the digital revolution (some fifteen years ago!). We lost countless hours and alienated (or at least made life a lot harder for...) a lot of photographers and design bureaus due to some prepress personnel desperately clinging to the "dpi" way of thinking at the input side of things. I don't think I'm exaggerating when I say it cost us at least a few millions per year, paid hours and late delivery fees included.
A smaller firm will have a smaller loss - but in "percent of revenue" it will be the same. Just do it right, and save everyone a lot of aggravation (and money!).
