Explain what you mean by PIXEL distortion. Also are you resizing the photos? We will need to have a few more details before we can really help you.

You have to resize it to upload it here. also the picture about is out of focus so it is hard to see what you are talking about.

Also since yoiu have not filled out your profile we do not know what camera you have.

I suggest shooting in RAW if you're not, open your RAW file in 16-bit mode in Photoshop (Image/Mode/16-Bits per Channel) to do your editing and then save the output as a .tiff unless you need to compress for the web.

Issues like this generally show up when you're shooting in JPEG and the program does not have enough data to manipulate and as a result you end up with these artifacts. I agree with horoscope's advice, shoot in RAW format and see if this stops being a problem.

And just for my own edification, this image you've posted is not a small crop of a much larger image, is it?

I am not sure what you mean either, and you did mention PNG, but still, I fear your issue may be JPG artifacts. What JPG Quality setting are you selecting when saving a file?

Your image here is 960x640, x3 RGB is 176 MB RGB data size. However, your JPG file is only 28.1MB, which is compressed excessively, to be only 28.1/1760 = 1.6% of its original data size. That causes JPG artifacts and poor quality. It would be better quality if the file were at least 8x that size, better if 10x that size. Use a greater JPG Quality factor. A small JPG file is NOT a good thing. Make the file as large as you can. "As small as possible" is wrong headed, counter productive to quality.

This loss cannot be fixed now, the damage is done now, and it is NOT repairable, no matter what you do.

All you can do is to discard the file, and start over from scratch from the original image from camera, and save it at higher JPG Quality setting... More like JPG Quality 9, or at least 8. High Quality is a good thing. :)

Also make sure the cameras is set to Large Fine JPG also, the best possible. Or shoot Raw is a solution too.

Also check Photoshop menu Edit - Preferences - General, to be sure Image Interpolation is set to Bicubic - Sharper.
