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

comment What are the most notable differences between Canon and Nikon lenses?
Couldn't agree more with Alan. Outside of using a loupe to examine perfectly calibrated prints under ideal lighting, the differences between gear and brands is minimal at best, and moot in the general sense. What mattes more is getting out and using the gear you have. ;)

comment What are the pros and cons of lab prints versus using a printer?
Generally speaking, professional quality printers "start" at 13x19", and go up from there. I have an iP4500 as a general purpose and backup photo printer. It cost about $130, and an equivalent today is probably less. It prints some great photos itself, and with a calibration device, it could probably print professional grade. It is a dye printer, so it actually has a really high DPI, and looks great. It only has the basic CMYK ink, thus has a smaller gamut, but most of the time that isn't a problem. I tend to print most of my 4x6"-8x10" stuff on it, leaving the larger formats to the 9500.

comment What are the pros and cons of lab prints versus using a printer?
Aye, I've started purchasing third-party papers. I actually should have pictured some. I am partial to Hahnemuhle, which is what the Canon Fine Art papers are anyway. The true stuff is about as expensive, but there are far more options directly from Hahnemuhle. I also like Museo DFA and Breathing Color, they have some nice fine art papers as well. I've never seen Red River, I'll have to look into them. I'm becoming a bit of a paper snob, but its amazing the variety of tone and texture available. This Spyder3Studio was definitely worth the $500...I'll be able to print on anything now.

comment What are non-destructive edits and do they exist?
I'm not sure that either of those are true. Due to the algorithms involved for most applications, such as Photoshop, Lightroom, Aperture, and similar tools, neither of those edits would be lossless. Scaling is never 100% perfect nearest-neighbor, there is always some interpolation simply due to how the algorithms work (nearest-neighbor is still a sampling algorithm). Even rotation incurs resampling in most image editing tools, so there also loss when rotating. Outside of writing ones own tools that use purposely non-destructive algorithms, I wouldn't bet on those two being lossless.

@Alan: Gocha. I would call it "Cost/Quality Ratio" or "Cost to Quality Ratio" then, I think that would be a bit clearer.

comment What are the pros and cons of lab prints versus using a printer?
A Canon Pro9500 II, costing $700, has far fewer features, but has a maximum DPI of 4800x2400. It also uses Lucia Ink. From an image quality perspective, the higher DPI of the Pro9500 allows for more tonal range and smoother gradients than the imagePrograph. While you can definitely save yourself $700 (or $1200 if you want to have perfectly calibrated prints), and spend less per print with a lab, there really aren't any quality differences. There may be a quality bonus if you print images yourself, but you have to amortize the cost of the gear over its lifetime, so cost is higher at home.

comment What are the pros and cons of lab prints versus using a printer?
@Alan: I understand what your saying, however despite the fact that there are "wider" printers that cost a ton and are usually used by professional labs, my point is that they are not necessarily higher quality. As an example, the upper end of the "consumer/home pro" lines from Epson and Canon tend to offer higher maximum quality than the top of the line wide format commercial printers. A Canon iPF8300 costing $6000 has a lot of powerful features for commercial entities, but has a maximum DPI of 2400x1200. It uses Lucia Pigment Ink.

comment What are the pros and cons of lab prints versus using a printer?
Not sure about the "Quality vs cost" comment. I think part of the reason many photographers make their own prints is to eek every las ounce of quality that they can out of a print. (Many have wide-format printers capable of wide gamut, canvas and roll printing, etc., and many do their own print calibration, often with very precise equipment, and the cost is not very high.) Sometimes, you get what you get with a lab, since you don't control all the factors, and quality, while it may be good, may also not necessarily be the best it could be.

Its all about interpretation. RAW is just information about reality that has substance but no real form, and how we interpret that information, what form we give it, determines how realistic and true-to-life the final shot looks.

comment What are non-destructive edits and do they exist?
I don't recall stating that RAW itself is a destructive representation of reality. Perhaps a better way to put it is RAW is a "limited" representation of reality, although considerably less limited than many representations (i.e. JPEG, or even Film). I do agree that as photographers, we should do what we can to preserve as much about our scene as we can. However, to preserve the "most" with RAW, that usually means taking a shot that does not "look correct" initially, fundamentally requiring some post-processing to interpret the information we have captured as realistically as possible.
