OK Photo-Paint users,
I thought of a question that has been bugging me for a while. Perhaps you could shed some light on this for me.
I am confused about checking and maintaining the dpi of a hi-res image.
Here is my usual situation:
I take a high-res image using a Canon 20D which shoots 8.2 mega-pixels.
A typical image size is 3504x2336 and it's between 3 to 5 MB depending on the image of course. The camera saves them as .jpg
I open it in PPX3 and do a few things to it and now I want to save it at the same hi-res it was in the first place.
Is it best to just do a Save-As and maybe choose the TIFF format, or choose .jpg with no added compression and a 4:4:4 sub-format?
How do I check what the dpi was in the original photo?
Should I be using Image / ReSample to save it?
Resample always defaults to 72dpi for web images. If I bump up the dpi setting to 300, does that have a bad effect on the image?
Anyway, what's the best way to maintain the highest resolution for printing large images?
Thanks in advance!

JPG is a good format for screen, but not for printing. TIFF is better, CPT and PSD too, specially if you have transparent background. How do I check what the dpi was in the original photo? Open the original image, and go to File/Document Properties. There you will have image resolution (Width and Height) in Pixels. Should I be using Image / ReSample to save it? Not, to save it, but to resample if you need it. Resample always defaults to 72dpi for web images. If I bump up the dpi setting to 300, does that have a bad effect on the image? If you enlarge document original size, this will have a bad effect on the image. May be not so bad, depend on image quality and amount of enlargement. Anyway, what's the best way to maintain the highest resolution for printing large images? This depend on image resolution, how large will be printed, and how close will be viewed.
