My sister in law has asked if she could enlarge one of my pictures. I've never printed anything above an 8 x 10 and my knowledge of printing and ppi/pixel requirements are limited. She has asked for the below specifications:
"I’ve calculated that an image 2.46w (97”) X 3.45H (138”) would need to be approximately (97x250) + (138x250)= 24,250 x 34,500 Pixels but even 150ppi instead of 250ppi would do the job for me."
My query is - can I check in Photoshop what pixels/ppi my jpeg is, and would it print ok if the pixels/ppi are larger than her specs?
