Under View>View Options (ctrl+J) in the Library I would like to see a choice for Cropped Megapixels so I can see at a glance how big a print I can make without stopping to multiply the cropped dimensions, which is a choice.

I don't understand the request.

Megapixels is a measure of area. Do you think of print size by area? (That is, you don't think "8x10 inches", you think "80 square inches"?

If you think of print sizes by their linear dimensions (in inches), I'd think you'd want to think about your image files by linear dimensions (in pixels).

no he means megapixels.

eg. If you are shooting with a 5D in sRaw1 you have a 12 megapixel image but then you crop in the picture a little bit closer brining you image to about 9mp.

this way you can see how big of a print you can make.

I do think this would be better if you can type in a print size and it tells you ppi. That would be a little more useful.

I still don't get it. How do you translate megapixels to print size? What if you have one file cropped to 3000x4000 pixels, and that's cropped to a panoramic 6000x2000? They're both 12 megapixels.

Megapixels just doesn't seem to offer as much information as linear dimensions. I'm sure I must be missing something fundamental...

In case you want an interim solution, DevMeta supports this (cropped megapixels as metadata for viewing in library panel, library filters, and smart collections).
