software to fake it, it doesn't give you the same quality

F Stops.<br>
The biggest difference you will see when using a single
image is that the darker parts of your fake HDR image will
be very grainy/noisy and there will also be some noise
that spills over to the rest of the image.<br>
<br>
You can do a lot better if your single image is a RAW
image with it's higher bit-depth instead of it's JPEG
equivalent, but even then, without the longer exposure
time that you would get from using a larger F-stop the
data simply isn't there is be able to expand for HDR
(really tonemaped) images.<span class="HOEnZb"><font

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>

rel="noreferrer" target="_blank">https://www.youtube.com/watch?v=hHJAJziWDs0</a><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>

<div> 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>
