LuminanceHDR for exposure blending. GIMP is
waaaaaay too much work to get just one way to
blending the images. Luminance on the other hard
offers a tons of different methods and then you
can tweak the settings within each method. It's
all very easy and gives you much better results.<br>

thank you so much man. I really appreciate it.
I certaainly will devote<br>
10% of my available brain to these videos
tomorrow. Do you know of any<br>
videos or text teaching how to do exposure
blending with gimp2.8? all<br>
the tuts I've been finding are incomplete or
are how to do it with 2.2!<br>

There's a ton of ways to do what you
want. The biggest thing you<br>
will have to worry about is lighting.
For instance, if you are<br>
putting something that was lit from the
left into a scene that was<br>
lit from the right, then there is little
you can do. No matter how<br>
carefully you add it to your scene your
brain will always tell you<br>
there is something wrong with the
picture.<br>
<br>
I tend to use a couple of different
techniques to put one image into<br>
another.<br>
If the background is a relatively solid
color, I'll use a technique<br>
similar to this example for cutting out
images while preserving fine<br>
details (hair in this example)... hint,
you don't use ANY of the<br>
selection tools, or copy and past.<br>

<br>
The other way I like combine image is
brushing out the background<br>
using layer masks as demonstrated in
this video with the leg:<br>

<br>
I usually use a combination of the 2
techniques since you rarely get<br>
perfect results with either method.<br>
<br>
All these methods ultimately use layer
masks, which is a much better<br>
way to combine photos than cutting and
pasting since you can tweak<br>
what is transparent or not back and both
without having to commit to<br>
a certain part of an image like you do
with cutting and pasting.<br>

I found a way to super impose an image
but it looks tacky.<br>
The method I learned was to open both
files and then to select the<br>
image you want to put on the other
with fuzzytool. I found that<br>
didn't work so I used the path tool.
Well I cut the image out but<br>
the paste doesn't look good. It is out
of scale. For the purposes<br>
I need WHat ithe best way to cut a
house out and put it on a blue sky?<br>
