I am a relatively new photographer, having been at if for only a few years. I chose Canon gear when I finally took the plunge into DSLR. I am an avid hobbyist now, and love everything about photography, from the gear, to the science, to the art. I spent years reading about the technology and photography theory, so I am very well versed in the technical aspects of photography. My artistic skills are moderate, but improving. You can see my work @ the following sites:

My interests lie primarily in nature photography:

  • Birds
    • Songbird Setups
    • Shore Birds & Waders
    • Raptors
    • All others
  • Astrophotography
    • Moon
    • Wide Field
    • Deep Sky
  • Landscapes

This should really be CW, as I don't think there is an objective 'answer' here. Unless anyone objects, I'll convert it later today.

comment Measure screen brightness using Spyder3 software?
Well, you can fully "calibrate" your screen. If you want other capabilities, like luminance evenness measurements, brightness metering, etc., you need the new software. You bought the Spyder3 Pro, which is EXTREMELY cheap for a calibrator, and a pretty good deal. Given that the upgrade is $20, even after that, you still get a REALLY good deal on an excellent calibrator. To contrast, the screen calibration package from X-Rite costs about $1500.

comment Measure screen brightness using Spyder3 software?
Aye, thats how I got it myself. I just purchased the Sypder3Studio SR, and got the upgraded Sypder3Elite software for free.

comment Measure screen brightness using Spyder3 software?
It looks like the upgrade is actually only $19... I guess they dropped the price. For that price, I would totally get it. Its got a ton of features, nice graphing, multi-screen comparisons of statistics, etc.

comment How to apply color management to the Windows 7 mouse cursor?
HA! +1 for the giant cursor bit. :D Between you and Guffa, I bet the problem is that its rendered by hardware, rather than the OS. Thanks for the tip.

comment How to apply color management to the Windows 7 mouse cursor?
I guess I could also just download some cursors. I know there are plenty of free cursor sets on the net. Good idea!

comment How to apply color management to the Windows 7 mouse cursor?
I have the Apple Cinemadisplay 30". It only has three controls: Backlight +/- and Power. The Spyder3Elite software is very powerful, and it can automatically control many aspects of the screen hardware, including brightness and such. I guess color temp is just one of the things it can't control.

comment What should I do to switch my gear from Sony to Canon?
When it comes to sensors, Canon has recently made some massive headway in that arena, with its new 120 megapixel APS-H sensor. Thats kind of hard to beat. Might be something to think about regarding future upgrade path, in addition to John Cavan's answer.

comment What should I do to switch my gear from Sony to Canon?
Excellent answer. Double what BBischof said. Interesting fact about Sony sensors, never knew that myself. Kind of makes the question of Sony vs. Canon all the more important if they really do service 50% of the worlds sensors.

comment When shooting in mRAW or sRAW, how does the camera generate smaller files?
I'm not sure about lossless compression. That would probably be very brand and model specific, and likely not a feature that every camera model uses. Most RAW files are truly raw, untainted data from the sensor, without any compression of any kind.

comment Do super-super-lightweight tripods exist?
Aye, its pretty floppy. That was my concern about it, and the reason I went with the Gitzo stuff. Even the Gitzo one is a bit light, and just a couple days ago I was worried it would blow down a mountain I was photographing because of some strong winds. ;P

comment Any good tutorials for learning how to post-process images?
I would agree that this should be community wiki. All of the answers below offer some great information, but there really isn't any particular "correct" answer. I'm not really sure what will happen with the bounty if it is converted, though, so I figure its best to leave it for 5 days before doing anything about it.

comment What software do I use to remove part of a photo and blend that space?
+1 for the trial idea. Content-aware fill is very effective at removing unwanted content. It is not perfect at generating content to fill in the space left behind, and uses a mixture of cloning, healing, and generative algorithms. If the content filled in is not perfect, it is usually a good enough base to manually add in any missing fine details.

comment Is Canon EF 17-200 f/4L USM a good enough lens for Canon 7d?
Rather confusing question. I think there is a Sigma 17-200, and a Canon 18-200, but not a Canon 17-200.
