A quick play with IR this morning as the ducks were not very playful today. Couldn't decide if this should go here or landscapes subforum so mods feel free to move if desired.

All shot on Sony A350, Sony 50mm f/1.4 with Hoya R72 filter. 1s, f/1.4, ISO400. With the long exposure, hand holding is not an option. I used available surfaces like benches, fences or walls to put the camera on, which severely limited my shooting positions.

Post processing was a red-blue channel swap, then fine tune colour balance and levels. Resize and sharpen. #4 gave me a bit of trouble as I couldn't get both the clouds and ground to look right. In the end, the clouds came out vivid yellow so I desaturated them and increased lightness to balance. You can also see some lens flare in that shot.

Flare was a problem as I couldn't fit the filter and hood at the same time. I tried to manually shield the lens front from the sun by hand where necessary but obviously didn't do well in that case. The ones that came out better had the sun behind me, which makes sense as more of the light would be reflected back I guess.

I'm tempted to go out again with the 50D only and see how that compares. I will bring a tripod though!

I did go down the park again, and took a selection with the Canon 50D and Canon 50mm f/1.8 lens. I used a gorillapod SLR zoom and a cheap ebay remote release which stopped working while I was there :( Settings are more varied than before so I've listed them individually.

Image
5: 1s, f/1.8, ISO800

Image
6: 1s, f/1.8, ISO400

Image
7: 1s, f/1.8, ISO400

Image
8: 6s, f/6.3, ISO1600

Image
9: 1s, f/4, ISO1600

Of the Canon set, only #5 gave me trouble with the excess yellow creeping out again.

In general, the Canon seems to give closer to the common blue and white look without minimal processing, whereas the Sony seems to have more red mixed in. Bear in mind of course red and blue channels are swapped from as taken.
