Cropping Question - DPChallenge Forums

I understand that cropping is allowed under basic editing, but can you crop with an elyptical or round shape? That leaves the white background around the square unfortunately, but it worked for a photo and I wonder if that's ok. Thanks in advance, Judy

It's an interesting question; I've often wondered the same thing. In order to accomplish this crop you need to make a selection with the ellipse tool and invert the selection/delete the BG, and that's a no-no, but effectively that's exactly what you do, in rectilinear form, when you apply the crop tool.

I have PS 7.0 and an easier Roxio software that you literally cut and remove, which I guess is what you said, but in Roxio, it isn't as technical.

Thanks. I figured as such, but I was just trying to get rid of some stuff around the edges to make a point, and that was the only thing that worked.

Oh well.........Judy

You can do it if you shoot with a teleconvertor and shoot at the widest to get vigneting :P

Here's the thing of it: let's play a thought-game and assume that site council will allow other-than-rectilinear crops. On the surface of it, an oval crop ought to be ok, philosophically apeaking. But what if we get into assymetrical crops? What if we decide ALL we want to see is a single figure out of a crowd, for example, and make a selection of that figure and "call" it a crop?

So my guess is that anything other than a rectilinear crop is gonna be disallowed.

Could you put that in layman's terms? Sorry, not familiar with all of the photographic jargon yet. :~)

LOL. He's saying that a tele-converter (a lens added between the lens and the body of a dSLR to get extended tekephoto capabilities) will not produce even coverage of the entire image area unless is stopped down. So it will vignette", darken the corners.

Is this layman's terms? probably not...

Anyway, darkening corners does not equal cropping to an oval.

Ok, I understand about the "over cropping" aspect of what you're saying, Robert. But where do you draw the line? I guess that's a discretionary decision, but it makes sense that anything other than the squared off cropping, would be disallowed. Yet on the other hand, any removal of outside, to get to inside, so to speak, whether it be plumb, level, or curved in nature is still cropping.... Ok, here we go... another discussion of semantics. LOL

Look at it this way: suppose you had a fixed-focal-length lens camera, no zoom. And I have a nice Nikon 5700 with a serious zoom built in. You and I are standing in the same place looking at the same thing. I zoom in to get it, you shoot it at fixed length and crop to get what I zoomed for. The playing field is leveled. That's what "cropping" is about. So that I don't "win" every time because I have better glass than you do.

Right. I totally understand.

Thanks for the clarification.
