Kind of scratching my head right now with something I'm working on. I'm trying to cut out a portion of a photo and adjust it to make a perfect parallelogram, such as:
When I copy this selection to a new file and attempt to skew/distort the corners, it does so to the rectangular area of negative space and image, not the selection's corners such as A, B, C, D above.
How can I manipulate those exact corners of the selection only? I am trying to position them in exact locations on a grid so that, when copied and pasted back in, the edges align as I need them to.
Any ideas? Thanks.

Note: I should add that the selection I'm taking from the original image is not a perfect rectangle, but an unequally shaped parallelogram, if that makes sense. I need to take that selected portion and perfectly adjust it to become a perfectly balanced parallelogram as shown above.

corel draw...
- now seriously, i don't know. i also don't use corel. its an interesting and useful question.********

Depends on your content. If you try and do it with a face for instance, you'll notice the distortion without a fair bit of PS work to fix all the edge pixels. If it just scenery you might be able to fudge it. Either way, I'd approach it by making a quick mask of the areas where the edges should meet, apple+j to a new layer, do your transformation and then go to town making it look good. Keep a selection of the parallelogram as well so you can overlay or multiply a wee bit of colour over it at low opacity to accentuate the shape you're going for. Dunno if that's helpful but hopefully a start.

Try to transform it into a smart object and then transform.

Transform and then move each corner or side individually, using the command key.

right click layer > convert to smart object

I should maybe more specific. This is a portion of a photo cut into a parallelogram shape. I can't do the same thing as the example above where it is a vector shape. The image was cut out of one image, then pasted into another, where I'm trying to ensure that all top/bottom, and left/right are equal lengths and angles.

draw the shape on a mask layer on the photo... simples.

Oooooohh... I see, the flat image you're starting with is already skewed and you want Photoshop to read your mind and know that you want your Transform starting point to be skewed for you. Maybe fadein11's suggesting of drawing a shape layer might work. Otherwsie, good luck tryign to get your hand on the original, uncropped image.

FINALLY figured this out, to a degree. The Warp tool allows for far more flexibility in transforming an irregular shape. Having some pretty good luck with it.

New question!
Working on some artwork that features a crop of a photo.
I now want to replace said photo crop with a higher res version that was just provided to me.I've done it before and did a pretty good job matching the lower res position by just turning the opacity of the new high res one down.
Surely there's a more efficient way to do this perfectly, with specific blending modes maybe ?
- Depending on the image I go between screen or multiply and resize until happy.PhanLo
- invert then set new layer to 50%. scale and transform until the work area turns grey with as little detail as possibleimbecile
- I use imbecile’s tekscarabin
- Except instead of changing the opacity i change the layer blending mode to subtraction or difference or some weird shit (i forget which)scarabin
- Thanks guys, will try all these!spl33nidoru

convert layer to smart layer.
change smart layer size to the high res dimensions (remember by how much %). place your high res image.
transform smart layer by used % in original comp.- the issue is that I was first provided with a lower res cropped version, and am now being given the full image, so can't match the %. Still useful another time!spl33nidoru

The trick I believe is to set the image physical size (inches or cm) the same as the low res, while maintaining the same pixel count. The only difference would be the dpi. Photoshop considers them the same size despite one having far more pixels. That way the image swap is the same dimensions and therefore no resizing has to happen.
- Just realized your new image isn’t cropped. This method won’t work. Best of luck.monospaced

Use "difference" blend mode. This gives you the absolute difference between the pixel values of two layers ( |A-B| ). When there is no difference/perfect alignment, the layer is completely black.
You can use an invert layer adjustment if too hard to see the differences on the black background/
If you Ctrl+T transform you can move layers in fractions of a pixel.
- Making a smart object before sub-pixel fiddling might be better to preserve quality of the original image.monNom
