Just learning about photos, would like to know more about resolution and getting my digital photos to print good. Am using Photoshop 6, and a photo quality HP color printer. Have used Photoshop some
sort of a mid-level user. Heres situation, would greatly appreciate your suggestions.
-Opened a jpg image (187kb), made with a digital camera. Just want to sure up colors, and also change the size of the picture.
-The images original specs were Image > Image size > its Pixels=960×1280, Size=13x17approx, Res=72dpi
-I changed the image to Size=4×6, Res=1200, resample=bicubic. Prints good, although filesize huge (2.3MB). Questions are
1. RES vs. QUALITY. When I saved it as jpg, Photoshop asks for a quality. I used 8. Why does it (appear) to have TWO things that dictate resolution the res=1200 and the quality=8. Which thing should I adjust to get to a resolution that will print well. What if I used Res=300 and quality=10 is that better or worse that the former. What should I save the NEW and improved version as (and not lose data)? Why’s file so big? Can I delete the unadjusted original?
2. DOES IT KEEP QUALITY. 2) After resampling, have I downgraded the picture, meaning if I re-keyed the original figures would it return to nearly exactly as it was originally, or did it lose data in the first resampling that it cant recover?
3. WHAT ARE GUIDELINES. What do most people do to find a balance between giant files size and high quality print resolution for instance is there a rule of thumb or chart somewhere that a certain picture size like 4×6 should be set to res=X and quality=Y?
Thanks
