When you view at 100%, your software maps one image pixel to one screen pixel. Your software needs to "know" what the screen resolution is. Here, I have the screen resolution set to 72 pixels/inch.

Actual Pixels in Photoshop is the same thing as view at 100% in other software packages.

Thanks! Now I understand the reference.

Refresh my memory? What is 100% (other than all of something)?


In math 100% is equal to the whole. In this particular case a 100% enlargement would be a doubling of the print size! If your cameras normal output is, for example, a 36" x 48" 'negative'' at 100% enlargement would be a 72" x 96" print! Is that what you really want?

I don't. But I didn't try to imply that I was. My question was simply inquiring about the reference.
Besides, wouldn't 100% of 36x48 be like 36x48? Where does a 36"x48" 'negative' come from? My camera output is X x Y pixels, which can be made into any size print. (whether it would look nice is a different story.)
I can understand the pixel per pixel on the display explanation more logically.
Confused by your explanation.

I don't think pixels or inches make any differences in the doubling factor @ 100% more it is still twice as big
But inches are easier to vizulize. Do you describe a print size in Pix x pix or in height and width in inches?

Who are you asking? If it is me, I go by print size in inches, whatever pixels go in it.

This makes no sense and is wrong.
