I've tried experimenting with several Blending modes but keep missing the mark. I'm sure this has a very easy answer but I'm having trouble recreating the effect on my own.
I think I'd use
Layer > New adjustment layer > Curves or
Layer > New adjustment layer > Levels with a
- Start with black and white image with the trees or what ever.
- Black background and white foreground.
Select > All
Edit > Copy( the tree layer )
- You can hide the layer once you've copied it.
Layer > New adjustment layer > Levels
Layer > Layer mask > Hide all
- Click the layer mask thumbnail while pressing down alt
- Click the Levels adjustment layer 'thumbnail' to get out of the mask
- Alternatively click another layer and select the Levels adjustment layer again.
- Move the white arrow to the left until it starts to look a lot like your example image and increase the whiteness, if needed, by sliding the grey slider to the left as well.
Ok....but what did you try? what are your starting files?
There are many ways of doing this but since you are eager to use Blending modes, here you go:
- have a tree or whatever without a background
- convert the tree to B&W (shift + ctrl + u)
- invert the tree (ctlr + i)
- place it over the wood texture and use Color Dodge as a blending mode
- further play with levels and opacity to achieve the desired effect
- Do steps 1 and 2 from above
- Do step 4 from above but use Divide instead of Color Dodge
Also, the final result mostly depends on your images
