Cut, paste and blend technique question
Feb 14, 2012

I have a picture of a pine tree with dark sky as a background. I need to bring this pine tree to another picture with totally different sky color. How can I select the pine tree so that all individual needles are in and sky between them is out of selection? Or is there a way to roughly cut the tree with the old sky between the needles, paste it onto the new background and then blend the old and new sky leaving the needles intact?

It could be very difficult or very simple depending on the two images. Could you post them for us?

Thanks for responding Ronny. I'll give you links to the samples of what I have (not mine but they look pretty much like my images)

The tree and old sky:

The background color of the second image:

I don't know what software you have but I am using CS5 and the plugin Remask3 to extract the tree, added your new background, then used match color to let some of the golden color show on the tree. Also used Hue/Sat adjustment layer to desaturate some of the blue remaining from the extract.............Ralph

Well, here is my try using PSPX4, which was somewhat involved. I first I split the image into the RGB channels and used the blue channel to make a mask. Then further refined the mask by using Highlights/Midtones/Shadows. I copied and sized the gold colored background and placed it beneath the original image and used the mask to extract the original blue background and expose the gold one. Once this was done, I used a hue map to remap the residual cyans and blues to green. Here is the result:

I realize that the result is not perfect and that others may very well do better, but I am quite pleased with my efforts. I probably should have increased the warmth on the tree so as to make it more plausible with the golden background.

Regards...Allen

Another way is to enter Layer Styles and use the Blend If slider for the Blue channel.

This video has 3 tutorials. The second one demonstrates masking a tree in an image very similar to yours.

(This is specifically to do with using Topaz ReMask 3 software.)

Ronny,

You did that just using the blend-if slider without a mask? That is amazing..........Ralph

Hey Ronny, I just tried your method and couldn't believe how easy and effective that was without going through the masking effort. Thanks for that tip............Ralph

Hi Ralph,

Thank you for taking time to do that. I think this technique is quite suitable for casual adjustments. I am working on an artistic photograph that I want to submit as a contest entry so I need to blend images very accurately and make them look flawless even when zoomed in.
