I own a Canon PowerShot G3 camera and take all my pictures at the maximum resolution of 2200 X 1704 pixels. I have the Nikon View 6.0 software to organize and rename my pics as I download them with my
compact flash reader.

The question is the following : I did a batch resizing of a series of 2200 X 1704 pics to 1600 X 1200 with the Nikon software so I could see all of the pictures on my monitor and to my surprise, the file sizes remained the same more or less! What is happening ? Was the
pixel size reduced and did the number of pixels stay the same ?

Any help would be welcome.

I can't be a 100% sure without a little more detail but I suspect that when you "resized" your photos what you ended up doing was just changing the dpi. So the total pixels would remain the same but the dpi and the screen size is changed. This is a good thing since nothing is lost, image information wise.

You might be saving them at a higher "quality" setting. When you save a JPG file, you can choose what quality to save them at.

Higher quality=less compression=larger file

Lower quality=more compression=smaller file
