Testing, testing. Experimenting with colour control.

I've been learning more about the controls on my camera. (There are so many, and the manual is so confusing!) An article on Digital Photography School alerted me to the Picture Control settings, and I've been experimenting with them. The author recommends using a Flat setting for landscapes; it reduces blowouts or too dark areas, but needs careful processing later.

I took a few photos on Flat. They turned out flat. There was too much guesswork involved on tiny things where I didn't already know what colours they should be.

I switched back to Standard, and then, on a whim, to Vivid. This setting emphasizes colours and contrast, not really my style in landscapes, especially the grey-green landscapes of the Pacific Northwest. But it never hurts to experiment.

I turned to the aquarium; here, a vivid setting might help. Colours fade underwater, especially when the photo is taken through algae-covered glass. And here are the first sample shots, some good, some not so good.

A mud snail, Batillaria attramentaria, eating algae off the glass. Lightened, background noise despeckled out, and sharpened.

A grainy hand hermit, Pagurus granosimanus. The vivid setting shows up the blue bumps on his legs and chelipeds.

A carnivorous snail eating an inoffensive algae eater. I saw it first on the glass, prying the tiny snail off. Once the little guy was captured, the predator let go and dropped to the sand.

A nude hermit, recently molted, resting before he goes looking for a new shell. This was well back in the tank, where usually everything is greyed out. Post processing was only needed to reduce noise and sharpen.

Turned around and heading down to look for a shell. Despeckled and sharpened only.

And one photo that didn't quite work:

Orange-striped green anemone, Halliplanela lineata, on the glass.

The anemone was surrounded by extreme pollution; bubbles and swimming thingies, luckily behind the critter, but still confusing. The vivid setting highlighted them all, so the background had to be cropped out and re-worked; a long, slow job. But I'm impressed by the pattern in the base, so I've included the photo.

I went to Brown's Bay in the sunshine, with the camera set to Vivid. Bad idea; I've deleted all of the landscape photos. But I got a few critters under the docks, where the setting seems to have been helpful. I'll process those tomorrow.
