Title: Exposure Blending Tutorial
Post by: bretedge on January 11, 2010, 09:32:14 am
Hey folks,

I've been a lurker here for waaaaaaay too long.  I've posted a bit here and there but am finally jumping in head first.  I thought I would start off by sharing a "how-to" article I just published on my blog.  Written by Younes Bounhar, this tutorial walks readers step-by-step through the process of blending multiple images together to create a single image with an increased dynamic range.  I invite you to read "Exposure Blending by Younes Bounhar" (http://bretedge.wordpress.com/2010/01/11/guest-post-exposure-blending-by-younes-bounhar/).  As always, your comments are encouraged and appreciated.

it is a good way  when there are dark and light areas well defined, but with a sky through the trees it is much more difficult and this method does not work very well

all the examples that you can find Internet are always areas sky-earth , the method described above works very well (or others) and it's never a big problem
but when it is  a mix of branches and leaves on a  white sky one must fully protect the areas and blend the edges gently into the blue sky (often in  product mode),  it's impossible with a brush

Depending on how much contrast there is between the sky and branches (in at least one layer), blend-if sliders can be a really big help here.

with a white sky and fringes (without wind ! ) it can be a hard job not to see the work  ,  blend-if sliders (splitting the sliders)  is , in my opinion,  one of the best tools in photoshop
also making a smart object  , median mode, with the 2 layers , sometimes works well

These two application are working well blending images with high contrasts:

EnfuseGUI takes use of the Open Source application Enfuse:

Tufuse Pro is based on Exposure Fusion http://research.edm.uhasselt.be/~tmertens/...ion_reduced.pdf (http://research.edm.uhasselt.be/~tmertens/papers/exposure_fusion_reduced.pdf)
