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 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.

...then dropping again. In such situations, the device will launch right into a verification mode and start a resync, only to have power fail again right in the middle of that. I've never once lost any data on my ReadyNAS, and I've had it for years. It's a nearly impervious device, and it DOES regularly (weekly, on the schedule I've set) scrub and resync the array to ensure that the chance of bad blocks causing problems is extremely low.

comment Can I ask Lightroom to delete copied photos from the SD card?
@jdlugosz: Sorry, that is not the case. With the ReadyNAS, scrubbing is basically doing a resync. That touches every block on the device and verifies the data. It takes about a day and a half to complete, and the device is running heavily the entire time. The benefit of doing this on X-RAID is, unlike most resyncs, if the device loses power or is otherwise shut off in the middle of the scrubbing process, it will properly recover when it boots again. I've had some brownouts and power outages where the power flickers on and off a number of times, or dropping, then returning for a few minutes...

comment Can I ask Lightroom to delete copied photos from the SD card?
@jdlugosz: The Ready-NAS with X-RAID does regular scrubbing, which goes through all the data on the entire array and checks it out, reorganizes and optimizes it. So, there can't be silent corruption...the system is always checking itself, identifying bad blocks, and moving data. If a block on one drive is bad, it can always be rebuilt with parity.

comment How can I take long exposures on Nikon D7000 with a wireless remote?
Before we close this, let's make sure it really is a duplicate. The OP linked the original question, and stated the solution there did not solve his problems. I would prefer to see us investigate the question, root out the real problem, and possibly retitle this to better depict the issue at hand. In the end, I think that is a better approach to simply closing as a duplicate, as it would provide better internet search results, and possibly head off additional questions about the same thing if people can find the right answers for different, yet similar (not duplicate), issues.

comment Why can't I use my 64 GB SD card in my Nikon D60?
Just insert a new card without formatting. These cards are usually formatted right out of the box. See if that works. I have never formatted any of my memory cards even once, and I've never had any problems across multiple Canon and a Sony camera.

comment anyone knows how this guy edits his photos?
I think there is also some kind of soft contrast technique applied here as well, which is more than just curves.

It was definitely ProGlass...given that it slipped out of my holder a couple weeks ago and broke. :(

Try this: bhphotovideo.com/c/product/491474-REG/… The price seems to have jumped considerably. I bought mine years ago...it was definitely not that expensive.

comment What lens design limits derive from the width of the lens mount?
...when your flange distance is very short might help alleviate some of those concerns. However, even with (and maybe more-so with) a large exit pupil, the light for any given point on the sensor that comes from the opposite side of the lens will ultimately cause vignetting due to the pixel structure. It may not be a lot, but it will diminish sensitivity. A longer flange distance ultimately improves the collimation of light reaching the sensor, which alleviates those problems.

comment What lens design limits derive from the width of the lens mount?
I don't know that there is necessarily a limit, not within reason. So long as the light "cone" is in focus by the time it reaches the sensor, that is all that matters. You could narrow the cone at the last element...or you could enlarge it. Whatever is necessary to support the entrance pupil of the mount. Problems ultimately arise when the flange distance is very small. In mirrorless cameras, it actually becomes a challenge to bend light the right way to reach the periphery of the sensor, and at an angle that is conducive to the photodiodes actually receiving light. A larger exit pupil...
