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 What is meant by the “native ISO” when talking about DSLRs?
I have to agree. The more I learn about photography gear, the more I realize how little all the micro-measurements matter. Distortion, slight vignetting, base/native ISO, etc. are all pretty meaningless in the real world. Those that do have a visible effect can usually be corrected in post-processing these days, often automatically with the advent of lens profiles for various software. They may matter for scientific purposes, but its unlikely any scientific project would use any commercial grade equipment.

Have you tried photo filter adjustment layers in photoshop? They simulate actual warming and cooling filters.

comment Method to photograph a wide/long wall from a near distance and create a panoramic view of it
Take a look at the EF 50 f/1.2 L. Its peak performance is between f/1.2 and f/2.8, and if falls off after that. It has some of the most superb wide-open performance of any f/1.2 lens I've ever used. There is obviously some vignetting, however that is very easy to manage in post processing, especially with software that supports lens profiles. The vignetting of a wide lens can easily be eliminated before stitching. I do agree though that in general, wide lenses suffer from softness and vignetting which can make them less useful at max aperture.

Thanks Chuqui. At least I wasn't totally out of my mind. (I'm out of votes for the day, so as soon as I am able to up vote, I will. ;)

Regarding the math, I think its important for photographers to understand a little bit of it, given that what we do all the time is work with angles and distances and widths. Thats why I try to throw out a little trig every now and then, with a clear explanation of how it works, so people can have more knowledge to draw on in the field.

Softness at wide apertures is largely dependent upon build quality. Cheaper lenses do tend to get soft, however there are some fantastic fast lenses, f/1.2 and f/1.4 in the Canon L series line of lenses, that are relatively very sharp wide open. Also, an f/1.4 or f/1.2 lens allows you to stop down a bit to get better sharpness and still have a fast aperture, vs. a slower lens which wouldn't give you that leeway. A tripod is essential, however you run the risk of someone passing through your shot if you expose longer, and longer shots mean more time to complete the whole sequence.

comment How to change the time before Live-view turns off on a 450D
My 450D seem to turn off Live View at varying intervals. I am not certain why, however it seems to depend on the various exposure settings, primarily ISO. I am guessing it is adaptively trying to prevent any damage to to overheating...so its probably capped at 30 minutes, but primarily based on some kind of temperature sensor.

As a side note, this would have probably been best as a comment, rather than an answer.

comment Where can I buy sets of Lee ND filters?
Aye, Lee filters are finely crafted tools. Thats why I chose them, they seemed to have a solid work ethic and there is certainly no question about the quality of their stuff. One thing I didn't research before I bought the system, however, was the availability of their stuff. Non-standard filters are easy enough to get, but the foundation kit, tandem kit, ring adapters, ND/NDGrad, and Coral/Coral Grad filters seem to be notoriously difficult to find in stock anywhere.

comment What are the pros and cons when shooting in RAW vs JPEG?
I guess if you actually need to plug your SD into someone's laptop to share the images. I'm not sure how realistic that is, or if its only a hypothetical. Hypothetically, sure, capturing RAW+JPEG can be useful...my question is, is it REALLY that useful, or is it just a hypothetical for arguments sake? At least in my own work, I would never give anyone a copy of anything until I've had a chance to properly review the shots and at least pick the useful ones. If a client needed a quick preview, it is easy enough to batch output jpegs for my picks.

comment What are the pros and cons when shooting in RAW vs JPEG?
The real question is: Given that you can save a copy of a RAW file as JPEG later, why would you ever shoot JPEG? RAW+JPEG only really does one thing: consume more space. Sure, those jpegs are small, but hundreds of them consume quite a bit of space, and don't really buy you anything, since you can create them on demand from the RAW versions if you need them.

comment Where can I get an extension tube for micro-four-thirds lenses?
@Eruditass: Oh, I definitely don't doubt the power of natural light for macro. A ring flash would be for highlights and fill, and to provide some motion-stopping. I would say shutter speed is still important...even with flash, expose for too long, and you get odd ghost/translucent subject effects. I've encountered these myself, and I have a topic here on Photo.SE about it.
