I see it all the time. I prepare images of artwork for artists to enter art shows, juried competitions and for state arts grants. Your image prep must follow the written requirements exactly, including the spelling of the file name extension; jpg vs. jpeg. If you have Photoshop or Elements it's easy. In image size, specify 300PPI and then make the long dimension 800 pixels. It's imperative that you convert to sRGB before saving as maximum quality JPEG. You can't use Save For Web because it makes the resolution 72PPI. If you don't have Photoshop or Elements, e-mail me the images and I'll format them to the required specs and e-mail them back to you.
I received the instructions for a competition at a small local gallery. All entries (photo as well as other artwork) need to be submitted as JPGs on CDs. This is OK but the dimensions required seem curious, "...Images should be no larger than 800 pixels in the largest dimension at a resolution of 300 pixels per inch." This cannot be done in LR as the minimum size for printing at this resolution requires a 4" minimum dimension. I can do it easily in Photoshop but the image ends up being of relatively poor resolution (the file size is 319 KB). Nothing is said about what software will be used to view the entries (Windows Photo Viewer??? ). If I do a simple 4x6 image from LR, I get an out of spec file but one that clearly looks better on the screen. Has anyone come across this type of entry criteria? I'm tempted to send both files along with a not to the person who is doing the judging.
Thanks for any thoughts.
