I've got an image that I've rotated in CS5 (to level the horizon) and it's left the tell-tale wedge shapes along each edge.

If I try and crop, the software wants to resize to dimensions in CM (I just want to output the highest resolution that's left).

I've also tried Trim but it doesn't have any visible effect, despite following instructions I've seen repeated in several online tutorials.

Very new to PS so if there's a better way than crop/ trim please let me know; otherwise how can I use these functions to get straight edges again without affecting the image size?

Thanks in advance
 
Use the straighen tool to level the horizon and it crops the image automatically (to remove the empty wedges you get from doing it manually)

Sure I've seen that in Elements and failed to get on with it. Could't see it in CS5 though, must look harder
 
If you click hold on the eyedropper tool (immediately below the crop tool), you'll get a tool bar slide out, and the straighten tool is the one with the ruler icon on it.

No idea why Adobe chose to hide it where they did :thinking:
 
Eyedropper on toolbar, select ruler, drag a ruler out and hit button straighten on the options. Simples. :)

Dang.. too late ..
 
another way to crop in PS is to use the rectangular selection tool, make your rectangle over the image. Use slection>transform selection to finely adjust each edge, press return to anchor the changes to the selection then go to image>crop to make the selection into the size of the image.

If you delete all the dimensions in the crop tool you will also keep the original resolution of your image, just cutting off any waste that outside the crop area.

There is also a straighten tool in the lens correction filter. (filter>lens correction) Turn auto scale off and set edge to transparency. Make your straighten then press enter. Select the transparent triangle edges, go to edit>fill choose content aware fill in the drop down and it will fill those selected areas with parts of the image that it thinks it should be. Content aware fill doesn't work as well with all image types. But much better than the fill to edges in the lens correction tool.

ETA: The great thing about using a selection to crop, is you can set a size ratio for the selection and fill your image with that ratio (3:4; 1:1; 5:7; 8:6 etc.) I've never found a decent way to do this with the crop tool. It only accepts absolute measurements rather than ratios.

Thanks for all the suggestions. This last one sounds ideal as i need to keep the ratio as per the original. Generally I'm picking up PS pretty quickly now I've started but this function seems massively over-complicated

This way was just what I needed - thanks :)
 
Great, glad i could help. It's the way crops used to be done in early versions before the crop tool was invented! :)
