"Crop in LR4"



Is it possible to do an oval crop and, if so, what are the steps? In advance, thanks for any information.

John

Not per se, but you can achieve the same effect (I think) by using the Effects -> Post Crop Vignette controls. I don't use them very often so you'll have to twiddle things a bit, but in general you want to set the vignette all the way in one direction (so it'll be black) and then set the "hardness" of the vignette edge to be "sharp." I don't know which numbers these correspond to.

Brian is on the right track, John.

For a black vignette, set amount to -100
For a white vignette, set amount to +100
Set Midpoint to around 50
Set Roundness and Feather to 0
The resulting file will have to be edited since the vignetted portion
is not transparent.
Selected the vignetted portion in an editing program, delete it, then save for/export
as jpg-2000, png or psd to preserve transparency.
Others will correct me if there is another, easier way.

I victimized a random shot, and it turns out that the key things are to set Amount to -100 and Feather to zero. And if I crop it to be square first, suddenly I realize that this is the way for me to crop my circular fisheyes and mask out their non-image portions! Thanks!!!

I'm glad you asked this question! I was able to take the info and apply it to one of the problems that's been vexing me for some time, namely masking off the glare that occasionally shows up in my circular fisheye shots. Here's the "before:"



and this is the "after:"

Wow, Brian. That is a really neat shot and the resulting edit looks great. As I read and experiment I find that LR4 is pretty user friendly. I try to find an answer but if I can't the experienced Nikonians have always been very helpful. Would you mind sharing the steps you used in this edit?

There are two sections:

0) Shoot the scene with a circular fisheye! In my case, the long-discontinued Sigma 8/f4 AFD, but current offerings are limited to the Sigma 8/f3.5 HSM (FX) or Sigma 4.5/f2.8 HSM (DX). Nikon once offered the 8/f2.8 AIS, which is a better lens than either of the Sigma FX offerings, but which is manual focus, 5x the size and weight - and $2000+ if you can find one in nice condition. The original scene is a fountain at the Stowe Botanical Gardens in Belmont, NC (near Charlotte).

1) Post processing: import, crop to square format, Auto Tone, sharpening, edge masking. A little goofing around with color balance as this one was a bit weird out of the camera for some reason. This was the state as of the "before."

2) Masking to eliminate optical issues: Crop to exactly square format (Crop, choose 1x1 aspect ratio, crop to almost touch the actual image); Post crop vignette per above (Amount = -100, Roundness = 100, Feather = 0.)
