You can also stick on those heat strips you can buy from a Chemist.

You need to have infinity focus taped down before all this though.

I've invested in some USB hand warmer gloves and a AA-powered USB power source that I can take out in the field next time. I also have some chemical hand warmers from the chemist, but forgot to take them with me on that night.

While changing dew shields I accidently bumped the zoom range so some of the later ones were at 20/21mm instead of 17mm.

Can you go into a bit more detail about the layer process?

If the tree is in each shot I presume it would be a bit blurry and larger than a single shot because of the blur therefore how do you deal with that when using the masks?

Hi Niko. The composition of all shots was exactly the same. There's no blur - the tree wasn't moving.

I've attached a screenshot of the image in photoshop with the layers.

- The 1st vibrance layer isn't doing anything, I just didn't delete it.
- Layer 1 Copy is the foreground - you can see the layer mask where the white is the visible part. It's the same image essentially, taken from a different stack - more of a lighter foreground.
- Layer 1 Copy 2 is just a copy of the background, with the blending mode set to 'color' to bring some more colour back into the sky
- The top 3 adjustment layers are just personal take for colour, saturation etc.

I hope that helps!

Thanks heaps! I love it too, can be both relaxing and stressful, but always fun.
