Default RELATIOINSHIP BETWEEN RESOLUTION AND IMAGE CROPPING

I am presently using a Canon A40 2 MP camera and am mostly pleased with the results. The only issue I run into is if I crop my images, the printed output of a 4x6 image is noticable not as sharp as an uncropped image. I understand the reason for this is caused by the reduction in resolutioin.

My question: Will buying a higher MP camera (say the A80 @ 4.0 MP) allow me to crop and still maintain picture quality? i.e. will a cropped 4.0 MP image = a cropped 2.0 MP image (within reasonable limits)? Or is the degradation also related to using a JPEG (vs. Tiff or RAW) format which introduces some compression?

Yes, if you're a fan of cropping, buying a higher resolution camera will help this problem.

It all depends on how much you crop. If you crop a 2272X1704 (a 4.0 MP image) down to the dimentions of 1600X1200 (a 2.0 MP image), the image's printout will equal that of the camera you have now. So yes, a higher resolution camera gives you more room to crop. Of course, this is only to a point, if you crop an image down to 722X630 (not enough MP), it will still print out chunky.

if you crop an image and save it later with lower quality compression you'll lose the quality... so if you crop, always save it as is - highest quality jpg (12 in photoshop i.e.)

Thanks for the advice! Jay
