I've been a software developer for a lot longer than I'm willing to admit. My current interests are C++ and Python on Windows, but I've been known to dabble in Linux and I try to be language agnostic when I can.

comment Where can I find comparisons for linear polarizers (for a cheap variable ND filter)?
Do you have a link to Pentax's claims that a Linear Polarizer is OK?

comment What are my best options for a tripod for up to $100?
I'm sure he meant ruing as in rue the day.

comment How can I better organise and file my photos?
The best way is with the Delete button. Now if I could only follow my own advice...

comment How do I correct white balance in JPEG images?
@Rowland, I should also mention that there are other methods in Paint Shop Pro that might be simpler, but I prefer this method as it gives the most flexibility. The Manual Color Correction feature is hidden in later versions, you need to customize the menu or toolbar to bring it back.

comment What file system are memory cards formatted with?
FAT16 had fewer patent issues so it was preferred for the smaller cards.

comment The right way to delete all photos from a camera
The camera manual will always recommend using the camera to format the card, as that's the only process they have any control over. Doesn't mean other methods aren't just as good.

comment Good examples of RAW's advantages over JPEG?
The conversion from RAW to JPEG not only reduces the number of bits but it changes from linear to logarithmic representation. Since our visual response in the eye is also logarithmic, you lose less from this process than the numbers suggest.

The added examples improve an already excellent answer - thanks for incorporating my meager efforts. +1

comment What are the pros and cons when shooting in RAW vs JPEG?
While downloading your favorite raw to jpeg converter into the camera might be a nice feature, I don't expect to ever happen. It would require too much standardization on the part of the camera makers with very little payback for them.

comment What are the pros and cons when shooting in RAW vs JPEG?
The 12 bits are linear and the 8 bits are logarithmic, so you don't get as much advantage as you think you do.

comment What are the pros and cons when shooting in RAW vs JPEG?
I have a method for fixing white balance in Paint Shop Pro, so I don't worry about that RAW advantage. When I got my Pentax K-7, I decided to stick to JPEG exclusively and I haven't regretted it yet.

I was able to get nearly all the way there starting with the JPEG, except for the blown out sky. imgur.com/NfR8p.jpg

comment What are Color Profiles and where would I find information on using them properly?
Note that using a larger gamut such as AdobeRGB might result in less accuracy overall if the image doesn't make use of the larger gamut. The tones of the image are forced into a smaller number of codes.

comment Can I publish photos taken in public legally?
It's doubtful that anyone can give you legal advice here, only guidelines. You'll need to talk to a lawyer if you need to be absolutely sure.
