I have a model of an iMac here. I put a screenshot of our geriatric care software on it. Unfortunately, the render result looks very "washed out". Little colors and little contrast. It feels like I've tried all the settings, but I can't get any better results. It seems to be due to the "scene environment". Could someone put me on the right horse here?

Many Thanks! George

  • $\begingroup$ Hello :). What exactly have you tried to solve this. And how did you add the image - using a shader? Real screens are backlit, what about this one? $\endgroup$ Commented Jun 23, 2021 at 9:00

  • $\begingroup$ 1. Your screen is not emitting light, so it's like it was printed on a piece of paper instead of a screen. 2. Your world is completely white with a strength of 1, which makes your piece of paper being strongly lit. 3. The sun lamp with a strength of 8 is also quite strong which overexposes the image a lot, too. 4. In the Color Management, the View Transform is set to Filmic and the Look to None, better would be Medium High Contrast or High Contrast. $\endgroup$ Commented Jun 23, 2021 at 9:36
  • $\begingroup$ Oh, and 5. since a monitor display is usually dark when it's not displaying an image, it would be best to plug the image only into the Emission input, and leave the Base Color a medium or dark gray. $\endgroup$ Commented Jun 23, 2021 at 9:58
  • $\begingroup$ Thank you for the complete review. As you see: We ware complete 3D-noobs, doing first steps in an unknown area ;-) We will completely rethink our scene setup when the opportunity arises, but since we have already finished some scenes, we currently cannot change "global" parameters. Currently the image is placed via a shader and the screen has no backlit. But I don't understand why the "headline" of the rendered screenshot is really black, but the "body text" is muddy gray. In the original screenshot, the body text has the same black as the header. $\endgroup$ Commented Jun 23, 2021 at 13:36

you could add a hue/saturation node, then you get this:

or with saturation 10:

UPDATE

as troy_s wrote here (How do you make an image emission without washing out the image?) you can change your shader like this:

enter image description here

and color management like this:

enter image description here

and then you will get:

and here another result with slightly different values: enter image description here

  • $\begingroup$ To get it more realistic it would help to first of all make the screen emissive. $\endgroup$ Commented Jun 23, 2021 at 9:56
  • $\begingroup$ @GordonBrinkmann : you are Right, but he asked for the „washed out“ problem, not for realistic 😉 $\endgroup$

  • $\begingroup$ Well, if you want to be nit-picky and just care for what he actually wrote... he was guessing it has to do with "scene environment". So before I change saturation etc. which changes the actual colors of the image, I would reduce the overall brightness in the scene and set View Type to Standard instead of Filmic... maybe even set the Specular in the Principled BSDF to 0 et voilà, it looks a lot better than before ;) $\endgroup$ Commented Jun 23, 2021 at 10:09
  • $\begingroup$ @GordonBrinkmann : you are free to write a much better answer than I did…just do it.😉 $\endgroup$

    $\begingroup$ Thank you very much for your answer. Its getting better... But I don't understand why the "headline" of the rendered screenshot is really black, but the "body text" is muddy gray. In the original screenshot, the body text has the same black as the header. $\endgroup$ Commented Jun 23, 2021 at 13:41
