Hi, I have never quite grasped how to blend 2 photos together when there are a lot of leaves and small details. I took 2 pics tonight I would like to blend together but no matter how hard I try I cannot select enough around the leaves! Can somebody please help me with this? I have a dark sky and would love to have the lighter foreground, but this tree is killing me!

I used the selection tool at 50% not-continuous, and selected the sky on the darker one, and then editted the lighter one and pasted. I then selected all the white parts that were peppered in the trees, and adjusted that separately. Not great, but it was the best I could do without masking all around the trees.

^ ^ That looks pretty good, especially working with a low-res file!

have you tried just running it through an HDR program? it doesn't seem like the leaves moved much between the shots, so it should be pretty easy to line up, and possibly give you the results you're looking for

There is a bit of movement b/w the shots (and they are in two different color spaces) which makes it a little more difficult. This is much easier to do with raw's. What I do is to try and get the two images closer in tonality before blending.

1. Darken the brighter image
2. Brighten the darker image
3. Stack the darker image on top of the brigher, Edit/Auto align layers
4. Put a black mask on the dark/top layer
5. With a huge and soft white brush at 100% paint the sky back in, go over the trees but avoid the shed, it's ok hit it a little
6. Once blended, adjust as needed.

Used Color Selection on the white sky and masked it. Used a soft brush at 20% around the tree to make it not as crunchy.

Sometimes you can get a pretty good starting blend by stacking one image on top of the other, aligning the layers and then choosing the top layer and using Blend If to limit the top layer to a particular tonal range. In this case, I put the dark layer on the bottom, light layer on top, aligned them and then used Blend If on the top layer and allowed the highlights from the dark layer to show through from underneath. To do this, in the blend if dialog you want to split the Highlight slider (OPT-click) and then pull the left Highlight slider half all the way to the left to the far shadow end of the grayscale. This will progressively blend the highlights from the two images.

Once that is done, you have a low-contra image with the full range of tones resented in the scene. You can use whatever tools you would like to increase global and local contrast, balance and edit color, etc. I gave the image a more painterly, super saturated look, but you could take this one in all sorts of directions. The sky is highly compressed and blocky in the posted preview images, so when you are lightening the sky and pushing the color contrast there, you reveal the limitations of the previews.

I went a little lighter than the doomsday sky look because, you know, there's no place like home....

Just for giggles I saved your images as tiffs and processed them in Photomatix. Opened the tonemapped tiff in ACR and applied a bit of Gradient filter from the bottom to middle or so to darken a little more.

Read up on using the alpha channels to make selection. Not as complicated as it sounds.
