0:00i will start post processing by dropping
0:03the shadow
0:04and ambient occlusion passes to
0:08photoshop
0:09so i will select both of them right
0:12click go to rasterize layers
0:15and i will now enable the shadow pass
0:18only
0:19so as you can see this is definitely not
0:22the result we are looking for and if we
0:24just play around with the opacity the
0:26effect isn't there
0:28so i suggest changing the mix method to
0:32soft light or overlay but usually soft
0:35light works better for me
0:37and once we do that you can instantly
0:40see much better result
0:42so let's hide and unhide the layer to
0:44see what's actually happening
0:46so you can definitely see the shadows
0:49get more visible in some areas let's say
0:53here around the counter as well
0:56i just think we are getting too much
0:59of this
1:00white uh highlight
1:03in our scene so we can either
1:06play around with the opacity slider
1:09let's say reducing it to 40 percent
1:12or you can also edit the layer using
1:16some of the tools like curves for
1:18example so let's
1:20do this with ambient occlusion if i
1:22enable it
1:23and send the mix type to soft light you
1:26can see
1:28the effect is still a little bit too
1:30dark
1:31so with my ambient occlusion layer
1:34selected i'm going to press ctrl m
1:36and open the curve editor now by playing
1:40around
1:42you can see i'm able to
1:44actually brighten up the scene and the
1:47result we have at this point is actually
1:50pretty interesting quite similar to what
1:53we were able
1:55to achieve
1:56with curves levels and exposure
2:00layers
2:01in the
2:02other video where i explained the
2:04photoshop post production and here we
2:06are able to have quite similar results
2:08using just the renderer layers so if we
2:10disable the ambient occlusion paths you
2:13can see it has
2:15a much stronger impact to our scene than
2:18just the shadow pass
2:20so i think we should definitely decrease
2:22the opacity of this ambient occlusion
2:24pass
2:25let's say to 50
2:27maybe
2:29and let's play around with it
2:32yeah i think 50 maybe 60 percent
2:35is enough for that
2:38let's now drag and drop glossy direct
2:41pass
2:43and as you can see again this pass is
2:46much darker than those two we've been
2:48using so if we set it up
2:52to soft light well this is something
2:56we don't want to have
2:58for this kind of passes with a lot of
3:00black
3:02areas let's use the screen mix method so
3:05what it does it actually cuts out all of
3:07the
3:08black values from the pass and it only
3:11leaves the highlights for us
3:13so now if we hide and unhide it you can
3:16see especially within those
3:18and those areas we are getting those
3:20very nice highlights
3:22of course they are too strong so
3:25let's reduce this effect
3:28to
3:30actually i think 20 25
3:33would be enough for that
3:36we can also uh play around with curves
3:40so let's see if it changes anything
3:44not that much if we only have 20
3:47few 25 percent of opacity so let's
3:50increase it and let's launch the curves
3:52again
3:56maybe if we increase the contrast
4:00will get something better well actually
4:03let's just keep it with
4:04this
4:05s curve increasing the contrast within
4:08this
4:09pass
4:11let's also reduce the opacity slightly
4:15and let's now add the final glossy
4:17indirect pass
4:19let's drag and drop the pass to
4:22photoshop
4:24and similar as with the glossy
4:27direct
4:29let's change the mix
4:31method to screen
4:33so this pass
4:35for
4:36in contrast to the other passes is a
4:38little bit too bright so let's decrease
4:41its brightness using the curves again
4:44we can actually go pretty harsh with the
4:46curves
4:48so you can see the reflections are
4:50becoming now much more natural
4:53yeah and if we enable disable the best
4:55we can clearly see this extra effect so
4:58also let's reduce the opacity to
5:02maybe 40 percent
5:04now i can select all of the passes with
5:06my shift
5:07select it press ctrl g to group them
5:11and let's hide and unhide everything
5:14so you can definitely see
5:17the immediate effect all of the passes
5:20have on our rendering
5:22right now i would suggest fine-tuning
5:24the results slightly so for example here
5:27i think the shadows are too dark
5:31we could fix that either by
5:34um enabling or disabling one of the
5:37passes
5:38changing their opacity i think the
5:41the shadow actually has the biggest
5:43impact on those dark points
5:45or we could also add a mask
5:48and using a very soft
5:50brush tool we could
5:53actually paint out
5:55those areas so i'm going to press f to
5:57go full screen
5:59change the opacity to 10 percent
6:02and just slightly
6:04click around this area to paint out
6:08those
6:09harsh shadows
6:12so i must say i'm pretty happy with the
6:15result i wasn't using passes in my
6:17original
6:19approach to this rendering but
6:21i must honestly say i'm really happy
6:24with how it looks like as you can see
6:26i'm just adding the curves right now to
6:28play around with the contrast a little
6:30bit more
6:31let's maybe go
6:33full screen with a black background so
6:36we have better preview on what's
6:38happening
6:39so just by adding those simple curves
6:44and maybe a color balance layer
6:47we would
6:49more or less have a finalized picture at
6:51this point so
6:53yeah
6:54if
6:56should you use the render passes that's
6:58the main question right now well i would
7:00say that definitely depends
7:02on the way you want to approach
7:04renderings you might also ask why
7:07aren't we using the renderer passes
7:09directly in blender
7:11my answer to that is it's a really
7:16much less user friendly as it is in
7:19photoshop so
7:20personally what i would suggest
7:22uh if you want to stick to blender i
7:25would just do the toner mapping and
7:27color adjustments there but if you want
7:29to
7:30work with the render passes i strongly
7:33advise
7:35dropping them to
7:36to photoshop
7:38but yeah now when i'm enabling and
7:41disabling them i must really say i'm
7:43really happy with the results so
7:45i really hope this video was informative
7:48and
