What are your favourite post processes?
« on: July 13, 2010, 05:11:05 am »
Adding that little bit extra to an image makes the world of difference in making a render really sing.
So i was wondering what does everybody else do to give their images an extra kick?

It would be great if you could explain a little about the process or give a tutorial link?

these are the processes that i've used in the past.

I like to add a little depth of field with a lens blur and then use a layer mask to sharpen the areas that i want.

I'm also a fan of Multipass rendering if i have the time

I've not tried this yet but it looks quite cool, lens warping.

So come on, share a few tips and you might even learn something

Sometimes I like to add a subtle vignette to make the subject pop a little.  Not so much that it's obvious, but just enough to darken the corners slightly.

I wish KeyShot had some basic post effects like this built in (I know of one render package that has vignette).

Another effect I'd like to see built-in is the ability to blur or soften the HDRI so recognizable objects don't appear in reflective materials.  You know, so you can use the kitchen HDRI with a car and not see a chair in the car's chrome :)

Thats a nice tip, I haven't used vignettes before so will be sure to give them try, thanks.

this tutorial seems to explain a good method.

Its personal preference but I like to keep the post effects separate from the render program,
I forever making small changes to images so if for example after an afternoon of tweaks i decide the vignette is a little dark i'd much rather tweak a photoshop layer than re render the image.

One of my favorite post apps is FilterForge.  I got it initially to create normals and bumps, but it is a super app with a lot of possibilities and uses.  Vignette, for example, with one of many downloaded filters, is a two-click process, with total control. Things like "watercolour", "serigraph" and the like are super, and I use them often in my fine art print line.  The app is so simple yet deep, and you can create breadboard style, your own filters.  So check out www.filterforge.com for the full story.

My pipeline is SolidWorks > KeyShot > Photoshop (seldom for post, except for minor tweaks) > FilterForge > Photoshop for print prep > Epson 4880.
