Losing sharpness when rotating image

12 years 4 months ago #182999 by Gammill
It seems when I rotate or align my image I'm losing sharpness in my photo. Is there a trick to not losing image quality when you align your photos? I'm using Photoshop, what can I do differently?

What's probably happening is, when you rotate your image photoshop see you are distorting the image (instead of making it better). Distorting the image will make it lose sharpness. Besides applying an unsharpen tool to it, I don't know of any other way.

I've always thought that the full 90 degree rotations take place without any loss of sharpness, so in Photoshop the Edit:Transform: Rotate 90 CW would be a lossless change. Same in Lightroom where the little arrows under the thumbnail rotate the image without changing it. Any other angle causes the software to calculate the pixels for the new image. I don't think I have seen a loss of sharpness when I have done it though - is it really noticeable? I would think if you did it several times, or rotated and then moved the image, you would get a problem.

If you open a file as a smart object, then any rotation and subsequent change to that always go back to the original file and so you don't get the same issue.

I'm no photoshop expert, but the only thing I can think of is your jpeg settings. If you are saving as jpeg you are recompressing the image, which depending on your settings can introduce a loss of quality.
