comment What are the advantages and disadvantages of using auto ISO on a DSLR?
My D7000 lets me set the highest ISO and slowest shutter speed to use in auto ISO mode, I'm not quite sure how it balances shutter speed and ISO in aperture priority mode within those parameters however.

comment What are the advantages and disadvantages of using auto ISO on a DSLR?
Is that always the case, or is there a level where pushing the ISO will generate proportionally more noise than boosting the exposure numerically in post would..?

comment What are the advantages and disadvantages of using auto ISO on a DSLR?
I've never thought about it that way, the fact that increasing ISO can lead to a less noisy final picture, but it does make sense now, thank you!

comment What are the advantages and disadvantages of using auto ISO on a DSLR?
ISO itself isn't about controlling those things, agreed, and if you do shoot in manual mode with auto ISO (which I never really had considered) you're in full control, but auto ISO in any of the other modes will mean that the shutter speed or aperture also vary unpredictably...

comment What are the advantages and disadvantages of using auto ISO on a DSLR?
Can you please elaborate on the point of lower ISO not giving less noise? Are you saying that taking a picture at ISO 100 and one at ISO 200 (with the same shutter speed and aperture), then raising the brightness of the first one stop in post would give two equally noisy pictures?

comment What camera has the highest number of frames per second?
@whatisname, it does have a rather impressive effective shutter speed however

comment Why are objects far away inverted through a lens but not through the viewfinder?
@Russel, it's exactly for the reasons you describe that I disagree with saying that the brain inverts the image. It gives the impression of there being extra mental effort involved in seeing because what is up in the outside world is down in the image projected on the eye.

Can people please stop saying that the brain turns the image around! The projected image is as much "turned around" by the brain as it is by the software in a camera - there is nothing requiring that the sensor (in the eye or digitally) should be oriented the same way as the subject is...

comment How to create candle reflections?
Probably off topic, but I've found that software developers are over represented among photographers (myself being one).

comment Nikkor 55-300mm or Nikkor 70-300mm on a D7000?
@dpollitt, I do understand that this can be seen as a duplicate, though I think you may have misunderstood my comment about it being worth it. I am not asking about moving from a DX to a FX body, I'm asking if it makes sense to buy this FX lens even though I'm (currently) on a DX body, a question which relates to the specific lenses as well as indirectly to the likelyhood of FX bodies getting more "consumer" in a reasonable timeframe.

comment Nikkor 55-300mm or Nikkor 70-300mm on a D7000?
@Dan, thank you. Ultimately it comes down to "is it worth it" considering that I currently use a DX body. I know it's a question without an objective answer but any additional information would be appreciated.

comment Nikkor 55-300mm or Nikkor 70-300mm on a D7000?
The accepted answer on the other question is that one is DX and one is not, which is already in my question. I'd like to understand how big a part the DX/FX difference makes and how much are other factors (and if so, what those other factors are).

comment Is there such a thing as a filter for circularly polarized light for photographic use, and what would be the effect of using one?
but light isn't necessarily one or the other. Linearly polarized is just one extreme example of polarization.

That picture shows light of specific polarization being converted from circularly polarized light and back, it does however say nothing about what the quarter wave plat would do to light of other polarizations, can you please elaborate?

@dpollitt, I'm not sure, but normal polarization filters can be used for so much more than "removing reflections from sunlight", for example removing (or boosting) direct reflections from a specific polarized light source such as a flash. Maybe there's something that can be accomplished with non linear polarized light that cannot be done with "normal" polarized light?

@mattdm, I'm interested in potential photographic applications though, not electromagnetic theory for its own sake.
