Hey guys,
I am working on a project in keyshot where i require a few shots with depth applied. In one of my shots, I have a few models scattered in my scene at various distances. When the depth pass saves out with this particular shot its saves an image with a black background and my models completely whited out. Thus, when i try to apply depth in photoshop there is no way to distinguish the depth. See the photos attached, I hope they make sense.
Thanks in advance for your help.
Best
Luke
Hi Luke,
take a look a this tutorial : https://www.youtube.com/watch?v=B_iMUp5gVsY
Hi Finema,
I have actually seen this tutorial several times, and overall I don't have any difficulty producing depth passes. But strangely with this image i'm having trouble. Could I possibly upload my scene for you to look at?
Thanks
Luke
Open the EXR file in Photoshop and chose "As Transparency".
Go to: Image / Mode / "8 Bits/Chanel"
Chose "merge" on the popup panel.
You should now see the depth grayscale.
Hey Philippe,
Thanks for your help. There doesn't seem to be any merge option in the pop-up at all?
Thanks
Luke
Check attachment ;)
@Philippe:
Are you sure that's a good way to do it?
Looks like you got some halo effect around the edge of the seating of the front chair. Probably from the HDR toning.
@blessid:
I was able to get some information out using the exposure adjustment. Check the settings below.

If you choose "equalize histrogram" instead of "local adaption" it actually looks pretty fine :)
Esben, you are the *man*. That's exactly the function I was hoping existed :D
*edit: Whoah, that's also working much better in the Lens Blur than matching the exposure & offset by hand. Thanks a bunch!

No problem. Pure luck.
I've actually been on a search myself for such a function. I'd thank Philippe for leading me to the HDR Toning option :)
... did I do that ?? ... ;)
What bugs me tho is .. why if near is black and far is white .. why is the background black ??

+1 to that one.
I think it's because there isn't geometry in the background.
If you add a backdrop ramp it will be OK. :)
Yeah I know ... but still it makes no sence. If there's no geometry, it means the view is towards infinity .. if far is clear and near is dark .. infinity would be bright white.
Yes... but it's useless to blur an empty space...
Well if you use a backplate image, it wouldn't be empty, would it ;)
Hey Guys,
Thanks for the responses and suggestions! @Phillipe I actually tried the method with adjusting the exposure and had similar results, but great effort! I've have only just come back to this post, so have actually finished my image. I had a similar thought to @Finema about there being no geometry in the background, so I actually added a slop in the background the re-renered my image. I then adjusted the Exposure in Photoshop. (See attached)
However, @Ebsben - "If you choose "equalize histrogram" instead of "local adaption" it actually looks pretty fine" - That's really good work, because looking at your depth map I can honestly say that it has come out better than my final depth channel did! In your shot you have captured the depth perfectly! I'm going to try this method, and think i'll combine it with the ground slope method and compare to my original results :D
Great work, and so kind for your efforts. You're all hero members in my eyes!
I'll be back with an updated shot :)
@Philippe > a backplate is an image , not a geometry :)
Hey guys,
Updated image. This time round I had a ramp in the background of my scene, and in photoshop i adjusted the exposure, equalised the image, then played with the brightness and contrast a bit. Let me know your thoughts.
