My office is in the front room of a run-down 12 megapixel sensor but the rent suits me and the landlord doesn't ask many questions.

Gonna hijack this for a question that's been bugging me: what's the technique for a shot like this? I was set up for a sunrise last month in a spot where I thought had potential and it turned into a tire fire. Basically the foreground was pitch black and no amount of bracketing or messing with sliders could fix it (and this ignores the fact that the composition wasn't as good as I had envisioned).

Is it a timing thing? Sun has to be a certain distance over the horizon to work? Or do you need a spot tilted downhill so it picks up light better?

A sample if you want to see what I'm talking about : http://i.imgur.com/ihMQMUW.jpg

Also, this hike owns. Did you soak your feet in upper grinnell lake? How long could you do it before your toes begged for mercy? :v:

Essentially it's an HDR shot with the saturation pushed a bit. You can bracket (or use a camera with a massive DR) and get this kind of result by merging the properly exposed areas of the different shots in PS, or you can use other software that stacks it automatically but generally doesn't do as good a job.

It's possible that's a single shot unbracketed if the sun had just, just came up over the horizon as well.

Haha nah, but I did stick my hand in, it was still pretty chilly. Stood knee-deep at Virginia Falls last year in early summer and everything below water was starting to go numb by the time I was done with the pictures.

VelociBacon did a decent job of explaining it, I would usually do multiple exposures but in this case it was a single exposure as I did not have a tripod with me. I think it depends on the scene really, I think your example works as is.

Here is a before from lightroom to give you an idea.

Good thing Vader didn't touch my bike. Good thing for him.
Haven't picked up my camera in a year, I think. I just haven't been motivated to do anything, but I took a last minute trip to Reno for the hot air balloon races. Didn't get anything nearly as good as before, but here you go.

This one is cool, but you got a nasty halo along the mountain ridge. Probably from sharpening.

I get this a lot too, partially due to sharpening, but only really visible when you knock down the luminescence on the blue channel. If you want to take down those blue skies like you would have in back and white film with a colored filter, without filtering the camera, you've really got to watch those edges. I've done a lot of fiddly work to get rid of them.

I do wonder what causes the thing. Is it oversharpening itself? Or is it an artifact of a large flat field of color that is only really firing on one of the sensor's three channels that gets strange at its edges?

Based on googling around, if it's a white band a few pixels wide that shows up along a high contrast line, it's oversharpening that does it. If you pixel peep there should be a matching dark band on the other side of the edge though it's harder to see. The sharpen feature is fundamentally using an edge detection convolution matrix to find areas of contrast and boost that contrast at a local scale. Think of what happens to an image when you use the emboss filter in Photoshop, it's sort of like that.

In practice, reducing the radius or amount sliders is what fixes it.

This is super helpful. Thanks. I was going nuts trying to get that halo out.
