Is it possible to change pixel size/count without changing physical image size and quality?

Hi There, It is certainly possible to change size and pixel count. It looks to me like you increased the pixel count (from the 900x800) and the result is 400x300. Your photo still has the same (total) number of pixels but they are more tightly packed. If you simply resize to 900x800 it will be larger but the pixel density will be lower. What you need to do now is resize the picture to 900x800. Look at the pixel count and make sure it stays at the quality you want. You will need to adjust both to get the desired result. You can usually find the size (900x800) and the pixel count in the same dailog box so you just set both at once. I do this often using Paint Shop Pro and Photoshop should be very similar. Once edited; save the photo with a new name so you do not overwrite the original. I usually click "Save as" and insert a "b" or "1" after the file name but before the ".jpg". example: image1.jpg is saved as image1b.jpg. That way if I "mess up" the original is still OK. Hope this helps, Al

If you use Photoshop then at the resize image window you can change size and/or pixel individually. Play with the checkmarks before doing changes.
