This is a very basic question, am just starting out in PS. My images are shot in RAW with Oly C5050Zoom (5MP). Some of my underwater subjects are very small i.e. 1 cm only. With the help of macro lenses, I can barely fill 1/2 to 1/3 of the frame sometimes.
Thus I need to crop the image a fair bit to give it a fair composition. I would like to print them as 4R size. What I have been doing is setting the crop tool size to 4"x6" with resolution of 300ppi and crop. How do I know whether the pic would turn out pixelated before sending it for printing? Alternatively is there a smarter way to do?
Thanks for all the help
