If you don't know what to do with your spare time, go walk your dog. If you don't have a dog, walk someone else's dog. It's a better way for you to spend your time than what you are doing right now. If you think you don't have any spare time, then you probably don't have a dog.

comment What setup would I need to photograph the numbers of a plane overhead?
How close is the plane? That might make a difference. Are you able to operate the camera yourself, or do you expect this to happen automatically?

comment In Lightroom how do I determine what collections an image is in?
@EsaPaulasto - strictly speaking, yes, it looks like a comment. But it's also THE answer to my question.

That was something I didn't know about. It gives me a list of collections that the image is in.

comment Why do two zoom lenses set to 200mm on the same camera produce different fields of view?
Posting the pictures might help. Also, if you were to adjust both lenses to produce the same image and report the focal length settings (read from the lens barrels) of both lenses, that would also be helpful. I suspect that you can't count on what the setting says about the actual focal length and the corresponding magnification, except maybe at the extreme ends of their ranges.

comment Lightroom -> edit in photoshop increases brightness?
What kind of image are you editing? I would assume it's not raw, but it does matter.

comment Lightroom -> edit in photoshop increases brightness?
Also, do the same thing in Photoshop. You want to make sure PS isn't changing the color space. (It could change from current to working, or it could be removing the embedded color space profile.) If the color space profile is changed, it will save in the new color space. This might give a different appearance on your monitor. ... You will actually find this option in Photoshop's Edit->Color Settings... dialog under profile mismatches

comment How do I expand a low dynamic range scene, in the analog domain, when shooting a photo?
@jrista - can you provide some images with their histograms to validate your answer? I'm on the fence about it, but leaning toward disagreeing. If you have some examples to show here, they would help. I'll look at it in more detail when I'm out of the office and share my own conclusions (unless some examples validate your answer).
