Why I use Photo-PAINT and not the other guy

And it would be better for David to ZIP up and upload the original and the modified PP files themselves.

This is not just an Adobe problem it's an issue of atmosphere and work habits as much as a soft display from Photoshop. People tend to be lazy, clients many times are cheap, the capture conditions were certainly challenging, however I saw the image on the photographers system and when he opened up it in Photoshop it didn't look like it does when opened in Photo-PAINT. It's clearly easier to see these issues in Photo-PAINT.

Which clearly accented the problems, which were definitely chromatic aberration, either over exposure or over sharpening.

In any case clearly a lack of care by the file creator since the client has no issues paying for the corrections and out of 30 images there were 4 with problems just as serious.

Yes I do criticize Adobe, PhotoShop costs WAY too much, the user loses there access to their files if they stop paying and for professional level imagine editing Photo-PAINT has almost everything needed, clearly a better display.

I don't think his claim is fake. I think he saw what he saw, then gleefully blamed it on Photoshop without much concern for what might actually be the problem. If his job depended on it, I think he might have dug a little deeper.

I must say though that there are some differences in how different programs present images that relate to performance. There are definite differences when you start zooming. Later versions of Photoshop (and Illustrator) have an option that hands off some duties to the gpu. With this enabled, you get a very different looking view of the same images. With this enabled, sharp edged, aliased, bitmap images appear blurry, depending on the zoom level. If your work depends on seeing this kind of thing accurately, you have to turn it off, or just turn it off because it's irritating on your eyes. That example is in Photoshop. In Illustrator, this setting immediately changes the appearance of the art. Everything becomes softer. Path lines, gridlines, etc all become aggravatingly thicker. But if you have an imported image that is hard edged hafltones, it makes it look beautiful. Normally, looking at halftones in Illustrator, they look terrible. You just have to know what is really there, but it looks terrible. That setting gives you an amazing preview of halftones. It's also supposed to make the interface faster but I haven't found that to be the case.

Halftoned bitmap images really show you a huge difference in the way different programs view images. Photoshop can do a really good job with it, but not at every zoom level. Other programs I use can't preset it well at any zoom level.
