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
  • Wildlife
  • Floral Macro
  • Insect Macro
  • Abstract

I currently use the following gear:

  • Cameras
    • Canon EOS 7D
    • Canon EOS 450D (Rebel XSi)
  • Lenses
    • EF 16-35 f/2.8 USM L Wide
    • EF 50mm f/1.4 USM
    • EF 100mm f/2.8 USM Macro
    • EF 100-400mm f/3.5-5.6 IS USM L Zoom
    • EF 600mm f/4 L IS II

comment How can I use a DSLR effectively with progressive eyeglasses?
@CountIblis: Could you write up an answer with that?

comment Will editing an image in a significant way alter copyright?
David's original comment is important here. We need to clarify the necessary locale, the jurisdiction within which you need an answer. Were a global community, so not everyone has the same law.

comment Will editing an image in a significant way alter copyright?
Vic, could you clarify the regions and locales the laws you are referring to apply to? We get a range of global visitors, and law may not be the same there. It is important that we are clear about the context of the laws we refer to in posts like this. For your own sake, unless you actually are a lawyer, you might want to throw IANAL in there as well. ;)

comment How do I generate high quality prints with an ink jet printer?
Sorry Olivier, I think that was supposed to be: (DPI/PPI)^2, since it's per square inch. For one row of dots, it would be DPI/PPI linear dots per inch. However, even squaring is not actually correct, since DPI is usually non-uniform in both directions...a 1440DPI printer may actually be 5760DPI in the other direction. That whole section should probably really be rewritten.

comment What is happening when I convert from a source color space AdobeRGB to a Canon photo paper profile?
No rush. :) I appreciate you taking the time to keep the post accurate.

@Kel: I don't disagree. My wording is poor in this post. I was referring to the X/Y coordinates of r, g, b primaries as they map to Lab space. I haven't worked with this stuff in years, so feel free to edit and improve if you can. Or provide your own answer.

comment What is the Base ISO of a Canon 5D MK III?
Actually, when it comes to astrophotography, on Canon cameras it is best to use full stop ISO settings. Because of the trickery Canon uses for the third-stop settings, you will not get properly linear results. If your doing milky way imaging, you should also be doing dark frame subtraction and flat field calibration. You need the most linear data you can get when doing that.

Also, remember that you can expand the height of the editing window when you do edit.

comment What do all those cryptic number and letter codes in a lens name mean?
I'll see what I can do when I get a chance. One thing I do not like about breaking it up, and this has nothing to do with it being my answer, just the value of it's contents...is there can only be one accepted answer. Breaking this up will mean all the content falls to the bottom of the page for most viewers using the default page listing. Not really sure I want to do that...

comment Why do my photos lack texture/detail/microcontrast?
What exactly are you looking for? Aside from some exposure issues...your images seem to have plenty of detail, and the color is great. There are some slight focus issues, but nothing I would attribute to the hardware...it just looks like your run of the mill micron misfocus caused by things moving in the wind, or you moving ever so slightly while taking the picture.

comment When to expose for the shadows vs expose for the highlights?
Nikon shadows will be pretty much the same as Sony shadows. They both use the same Sony Exmor sensors. Nikon actually does a better job with their RAW data, as it is true raw, not lossy compressed...so you might be able to eek more performance out of each file. Overall, though, the differences between Sony and Nikon cameras that use Exmor sensors is minimal. Your fine going with either brand. Almost everything out there these days uses Sony Exmor sensors. The exceptions are Canon, which use Canon sensors, and Samsung, which use Samsung sensors. Even MFD use Sony now.

...can be easily adapted. Both the Sony A series cameras (E- and FE-mount) and the Samsung NX class cameras, are mirrorless. That means short flange focal distance, which means just about any lens, of any brand, going back many decades, can be used on those cameras with simple and relatively cheap adapters. That opens up a whole different world of image quality that simply isn't available in the Canon line at the moment.

comment When to expose for the shadows vs expose for the highlights?
I used to be a pretty loyal Canon fan, but after watching and waiting for years for them to improve their sensor technology, I have come to the conclusion that they simply can't, because they either don't know how, or simply don't care. IQ improvements are being made in leaps and bounds by all the competition, and the best Canon has come up with since the 5D II hit the streets is the 5Ds...which MAYBE gets about half a stop improvement in noise performance. If you want better IQ...don't let brand loyaltee get in your way. Cameras come and go...and with mirrorless, lenses...

I personally have stuck with Canon because their high ISO performance is very good, and because their higher end lenses are phenomenal. I own the 600mm f/4 L II, and it is a beautiful piece of engineering and glass. I use that for birds and wildlife. That said...for most of my other photography, I've been moving to other brands. Sony has some compelling options, with IQ like you see above, for quite cheap. The A6000 and A7r II are on my list. I may get a Samsung NX1 for shorter focal length wildlife (w/ forthcoming 300mm). A QSI CCD camera for astro is on the way soon.
