I generally try to print all images for clients and require that they purchase a print prior to the release of any "small sized file" for holiday cards, web-use, but a faux-pas in my new (app-based) contract has a client requesting an image she didn't "buy" for the above listed use.
I need to create a size that will work well for a holiday card and web, but not for reproducing to a print. What should my LR output be to achieve this, assuming the card would be no larger than a 5x7?
Is there a formula that one can use to determine this on varied sizes? ,Say, 8x10 looks good, but at 11x14, pixelation occurs? 5 x 7 looks good, 8x10 does not?
I've posted in FB forums, however, the response was, "Trust that your client won't print large!" Um, right. This is the key image in the group and the only one that she selected yet didn't buy in 11 x 14.
