How do I constrain crop to a certain height/width ration (say 3:4) and NOT do any resampling of the image?

For example, I have an image 2304×3072 and I want to crop it so that the result still has the 3:4 aspect ratio, e.g. the result may be 300:400 or 750:1000 or something in between. But I don’t want to do resampling.

Is such an operation possible?

Daniel,

Try using the Rectangular Marquee tool.
Set the style (on the options bar) to Fixed Ratio and put what you want in the width and height boxes. (3 & 4?)
Then drag out your selection at the fixed ratio.
Then go to Image>Crop.
Before you start, check the Image>Image size to see what effect the crop has on the image size.

Yes

Use the crop tool but make sure to leave the resolution box blank, otherwise it will resample. Just enter your H and W in inches in the proper aspect ratio. (do not enter h and w in pixels, this will resample your image.)

You can also use the marquee select tool and then the Image/crop command.

Thanks for the "inches" metric. I’d searched the web and found the advice to enter the ratios in the size boxes with empty resolution but none of the advice specified using inches instead of the pixels.

I’m glade it cleared things up for you..

I believe you can use any of the dimensions (rt click in h or w box) allowed in the H and w boxes except pixels. I just like to use inches. It works really weird when you select pixels. The area you select is cropped and resampled to the pixel dimensions you enter. Never really found a use for this.

But when you use the rectangular marquee select/fixed size. You can select the pixel size of the crop you want. This I do use and find useful.
