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

comment Strange color difference between Rebel XS & 70D
Ah, sorry, I thought the XS was the 350D. Well, then there isn't as much of a gap in the fabrication technology. The 70D is definitely a modern fabrication compared to the 1000D, but I wouldn't expect there to be any significant difference in the response curve of the silicon.

comment How can I make successful abstract photographs?
I kind of agree with Michael, I'm not exactly seeing "abstract" in these photos. Maybe "not quite normal", but not "abstract".

comment Is the format for the distortion and chromatic aberration correction of µ4/3 lenses documented?
As for the downvote, I don't really care. I think it was unwarranted and unjustified, I don't think you actually read my answer within the context in which it was given (nor the timeframe, which was four years ago), but the only way to allow you to undo it would be to edit my answer...and there is really nothing to edit. I offered up the best information there was at the time, and I am not ashamed of that.

comment Is the format for the distortion and chromatic aberration correction of µ4/3 lenses documented?
@bronger: Your still missing the point. I linked THE BEST and THE ONLY information that was available, PERIOD, back when I created this answer. The links I offered are the only "documentation" that was available. If you actually read my post, I was well aware that the links I provided were only helpful for the OP to reverse-engineer a solution himself...BUT IT WAS ALL THAT WAS AVAILABLE. At least I offered as much as was humanly possible at the time the question was asked, rather than simply not answering at all because I wasn't providing the right kind of "documentation"...

@MichaelClark: Are you sure? I thought it was released in 2005. Were talking the 350D, right?

comment Strange color difference between Rebel XS & 70D
Agreed. The reasons the 70D is more expensive have less to do with the physical characteristics of the sensor or firmware, and more to do with it's capabilities and modern age. You can normalize the results with RAW in post, that is easy enough. If you insist on OOC JPEG, then you can still tweak the styles a little bit with the XS to get a result more similar to the 70D. I also recommend trying both cameras with the Neutral picture style, which should reduce any differences as the point is to minimize what the camera does to the image.

comment Where can one find Canon printer icc profiles?
I've actually been trying to sell my DataColor Spyder Pro package, which includes the screen, print, and camera calibration tools. Darn good deal, if your interested. ;P

comment Where can one find Canon printer icc profiles?
Ah. In the case of the MG line, I don't think Canon has ever produced ICC profiles. I know they had them for the PIXMA Pro9000 and Pro9500 lines, and the new Pro 1/10/100, but beyond that, I'm not sure that Canon has ever created ICC profiles for their other printers. Most third-party paper manufacturers don't create ICC profiles for anything else either. Your pretty much on your own in that case, in which case a SpyderPRINT as in AJ's answer is probably a worthwhile tool.

Do you mean these? Canon ICC profiles. If your on Linux, I'd guess the Mac ones should work. There should be profiles for each Canon paper type. Normally these are installed with the drivers, and on windows they can be exported, so if these links don't get what you need, I may be able to provide you with .icc files for the necessary paper types.

comment Setting white balance for raw image from Canon S100 using Lighroom failed to work well
...the default Adobe camera profile. Personally I use the Canon Standard or Neutral profile, which doesn't really mess with color or anything else in any way, then achieve the color and tone I want on my own with all of LR's other tools. It's also possible to edit one RAW image, then save those settings as an auto-apply profile for a given camera model, ISO setting and even serial number. That way, every time you import, your photos get the default settings YOU want, which can save you a lot of time in the long run.

@Paul: There really is no such thing as accurate or better or more correct when it comes to photography. Aesthetic appeal is 100% a human thing. You need to choose what style appeals to you, and in all honesty, I'd be willing to bet that the OOC JPEG quality is not the best possible option. Also, keep in mind, there are multiple camera profiles in LR. It's the last panel in develop. By default, Adobe's own profile is used, but replications of all of Canon's profiles are there. Pick one, and you'll probably get MUCH closer to Canon's output. It won't match 100%, but it will be closer than...

comment What's the difference between colour space and bit depth?
Using Matt's example colors, it would probably end up bright yellow (255,255,0), since that is the closest viable option. If you mean (255,0,0) then it would end up orange. There are various rendering intents that can be used when mapping numeric color values to color-space coordinates: Absolute, Relative, Saturation, Perceptual. Depending on the intent, the exact color outcome (the "rendered" color) will be slightly (or maybe wildly, really depends on the color space and ICC profile) different.

comment Why image at 400mm is LARGER THAN DOUBLE of image at 200mm? (according to lens formula)
Aye, linear magnification is the same as the ratio of focal length.

The reason your RAW image looks different is Lightroom uses Adobes algorithms, where as the OOC JPEG uses Canon's algorithms. The two are not the same. Canon publishes all the details about how to replicate their tone curves, white balance, etc. but Adobe chose to build their own system from the ground up (necessary, since they have to support hundreds of cameras in Lightroom). You can't expect LR to produce identical results to OOC JPEG images because of these algorithmic differences. They will be close, but not identical.

From a numeric standpoint, yes. From a rendering standpoint, it depends on the color space. ;)

The subject area increases by 2.25x (600mm shrinks the FoV in both width AND height), linear scaling is 1.5x. Think about it, though...the increase in area is more relevant, as it means you have that many more pixels on your subject. Pixels on subject is really where IQ comes from...the more pixels you can get on your subject, the sharper, less noisy, etc. for any given output magnification.
