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

comment Methods for dithering a DSLR
Dithering is currently a software thing, not a mount thing. The mount is controlled by whatever is doing the dithering (most often a guiding program). So I don't think there is a hardware solution for you. I have provided an answer that covers dithering, what it is, how it's down, the consequences of not using it (with DSLR anyway), and what software can do it.

comment Where do rays of light from one point strike the film?
I'm inclined to keep this here for now. The ultimate goal is to use the knowledge to support a simulation program, but the concepts are definitely related to photography.

comment Why does getting closer or zooming in decrease depth of field?
@MichaelClark: That is not my understanding of the question. I think the OP used odd wording, but I do believe he means getting closer to the subject with the camera, or using a zoom lens to enlarge the subject, thus resulting in a chance in DOF in the resulting photograph.

comment General guidelines on choosing a lens for an image sensor
@Naz: Sensors are pretty useless without some kind of lens to focus an image on them. As such, I think if you are trying to design a sensor, you really need to learn optics. It's kind of a critical bit of knowledge. There are plenty of resources out there that explain how optics works, for reflective or refractive elements (and combinations of the two)...educating yourself is really the best way to address your problems.

@Naz: Can you explain what you are actually doing? Were kind of working in the dark here...

comment What apertures are required to enable autofocus, including cross-type or high-precision focusing, on Canon DSLR cameras?
Thanks, DL. Looks good to me. We just need to get some upvotes on the new one, so it floats to the top. ;)

comment Can I ask Lightroom to delete copied photos from the SD card?
@jdlugosz: It's a full parity RAID, so it has full error correction information distributed across all the drives. In my case, I have four drives in my array. I don't know the underlying details, as in specifically how it verifies each block, but I know it can and does make sure the data is correct everywhere on the whole array when it is doing it's scrubbing/resync process. I've actually done a live (online) drive replacement...I took out one of my smaller drives, and added a larger one. The device kept operating, and automatically rebuilt the data on the removed drive onto the newly added.
