When you are editing portraits, do you crop BEFORE you edit, or do you (as I do), crop AFTER you edit allowing the flexibility to create multiple sized crops later?

I hear so many "PROS" talk about 'cropping' BEFORE - especially in Photoshop. Why take time editing something you won't use, they say! But what's discarded in Photoshop is gone forever and it's a bit hard (impossible) to create a usable 8x10 AFTER it was cropped to a 4x6 format, i.e.: chopped toes/elbows, etc. Also, it is hard to explain to a "Brides Mother" that the 16x20 Canvas Print she wants out of a 4x6 tight cropped Proof is not available! As a note, suggesting the 8x12 or 12x18 to the client does not count and isn't a fail safe solution. People LOVE their 8x10's, & 5x7's!

Keep in mind, this question is about editing People rather than wildlife or landscapes - unless - those images are contracted and the client has a stake in framing of the final product.

Thanks! And More:

Please feel free to expand on methodology and reasons why.

Here is one of mine: In Lightroom, I create a "Copy" of the final edited image, for each crop size I develop. I also "color code" each size differently. This way, I can sort the"yellows" (for 5x7) and get all of the 5x7's at once for a batch export. When I export a 5x7, I will include -57 in the batch naming process to distinguish it from the same image cropped to an 1114 - 11x14.

Thanks!!!

Hi, I am looking for a long reach lens that is fast and sharp but doesn't break the bank. I have looked at some reviews and I am still not sure. I use a Nikon d810 and a d4. Looking at the new Tamron SP 150-600mm f/5-6.3 Di VC USD G2 or the Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary Lens. I want to shoot wildlife including small animals and insects along with landscape. I use a nikkor 24-70 2.8 and nikkor 14-24 2.8 but really want something long without spending $10,000. Any input would be appreciated.
