Background quality drop?

Hi!

I noticed something really weird and don´t know what is causing it.

I have a background image for a render in Photoshop, it looks as intended, just as in my image viewer. I set it as a background in the environment tab and it looks brutally compressed. The size of the bg is 2000 x 2600 (the size of the render).

I am enclosing the difference between the two. Someone knows what could be the cause? I already checked the render settings.

 

EDIT: After posting, I noticed the image looks even worse in Firefox than it does on my PC. Left side should look fine. I am very confused. :P (the attachment shows the correct size, I only assume it compress things for full image, but that´s not the point lol, I am worried about DAZ Studio)

    The forum does compress uploaded images, try to download it and you'll see that it's only 61 KB. That the thumbnail shows the original size must be a bug.

    It's odd though, the thumbnail says it's a jpg while the image saves as a png (apparently it is, Irfanview use to complain if the extension is wrong and it doesn't).

    I've also noticed that my scenes appear to be a bit darker lately. I don't know if it's a related issue (or even if it's an issue at all - it might even be just me and my monitor or something). Has anyone else noticed a slight darkening of their scenes lately?

    It seems to be related to tone mapping. If I disable it, and set Gamma to 1 in the Image Editor option for the background image, the backround renders just as it should. Of course, I need tone mapping fot th scene to look as intended.

    Guess I need to use a better quality background image so the compression doesn´t show during render. Setting Gamma of the background to 2.4 seems to get it closer to the original result. I got too comfortable with the idea of the image background being independent from the render settings :/

    @Hellboy "I need tone mapping fot th scene to look as intended."

    Since you talk about rendering in Photoshop, why don't you tonemap there?
