Hobbyist photographer with a Nikon D5100.

I started doing photography in the late '70s (I was 10, and got a Minolta SR-1 from my father when he bought a Nikon F), but shelved the hobby in the late '80s. Picked it up again last year, this time with digital equipment.

Philosophically, I think photography is not much about representing reality. Although there is a subbranch of photography that does specialize in representing reality faithfully, those photos tend to be fairly dull (think passport photos or surveillance cameras).

To quote The Luminous Landscape:

The problem with reality is that it is often far too real.

When photos are for entertainment, art or decoration (as opposed to documentation), we don't want reality. We want drama, interesting colors, attention-grabbing tableaus. Or black-and-white subjects hunched over against the storm while trundling across an endless bleak plain, but in any case something that differs from day-to-day reality in some interesting way.

So I consider photography to be just as much about photoshopping as it is about wielding a camera. Whether you get a particular effect in camera or through software doesn't matter much. That's just a technicality, and the choice between in-camera and in-post boils down to what's the simplest way to achieve any given effect.

comment Is vector photography possible?
As you say, any bitmap image can be vectorized. Why should a bitmap vs vector representation matter for the definition of a photo any more than the 'silver nitrate on paper' vs 'RGB pixels' representation? If you mean that the image is generated from a 3D model rather than from the real world, we can already do that pretty well; we call them renderings. If cameras could construct and manipulate 3D models, so we get pictures that are part real-world, part rendering, I expect the discussion will be similar to today's discussions about Photoshop.

comment How do you achieve sharp bokeh circles?
Agree that it's (at least partially) a property of the lens, see also a few comparison shots here: rickdenney.com/bokeh_test.htm ("Test scenario 1, wine glass at f/4")

comment What is the best way to preseve old equipment without fungus and moisture?
Seems to be from $100 and up in Singapore: harveynorman.com.sg/digital-cameras/camera-accessories/… Not all that much compared to the cost of a Leica :)

comment Use the Nikon D800 to make short YouTube videos & still shots of an owner-build or am I better getting separate video and DSLR cameras at same price?
Why MF: Here's a demo - youtube.com/watch?v=ca_Cd2mX03w And an intro on shooting video with DSLR which covers various options like fluid heads and follow focus.

Haven't tried these myself, but I guess you're looking for a dry box - either an airtight enclosure with silica gel, or an electronic dry cabinet like these.

comment How to protect camera and lenses against “color bombs”?
Thanks, makes sense. So something like this, I guess: dicapacusa.com/ProductDetails.asp?ProductCode=WPS10

comment What's the difference between Canon's silent and non-silent shooting?
@mattdm It flaps the mirror more slowly, so there's less noise when the mirror crashes to a stop. Here's a comparison: youtube.com/watch?v=Rup3T6j_r9s In silent LV mode, it doesn't flap the mirror at all, and uses an electronic shutter in place of the first shutter curtain, so shutter noise is reduced by half - the only noise is the second curtain closing and opening again. (From a 7D review, assuming the 5D version works the same.)

comment Will there be a need for cameras at all once we have 4k video?
@dpollitt I don't think it would be too hard; I assume a photographer would mostly use the 30fps option when things are happening too quickly for burst mode to keep up. Watch the 30 second clip, find where something interesting happens (the tennis player hits the ball, the bride and groom start kissing, ...), and you may be down to a couple of seconds and 50-60 frames to look at in more detail. A bit of work of course, but hardly infeasible.

comment When I point my D5100 at a plain wall, why does it keep trying to focus instead of taking a picture?
+1, most likely. I have a D5100, and this is the default behavior if it can't achieve focus lock. Workarounds: a) Find something high-contrasty to focus on, b) turn off AF and focus manually, or c) switch to AF-C (continuous AF) and set the menu item "Custom settings > a Autofocus > a1 AF-C priority selection" to "release" rather than "focus". (That last option will let you take the picture, but it won't be in focus, so it may not be what you want.)

comment What is the best way to clean the sensor on a digital SLR?
Also, LensRentals has made video on sensor cleaning. Like for Tom Hogan, I trust that the people at LensRentals know their stuff.

comment Are there any comparison photos of different lenses (with the same camera and scene)?
@BlueRaja I guess "shootout", "review" or "comparison", plus the designation for two lenses, should net you most of them.

comment How do I take a photo of people before a bright window?
@user2019515 Off-camera flash positioned to the side of the window, so the reflection isn't visible to the camera. Or on-camera flash, but then you'll need to move the camera as Sitron_NO suggests.

comment How much do lens lineups vary across Mirrorless camera systems?
+1. A couple of unusual (for DSLR) options: An f/0.95 for Sony E, m4/3 and soon Canon M. And an "inverse teleconverter" for mounting Canon EF lenses on Sony NEX that reduces the focal length with 0.71x and gains one f-stop in the process. Don't know if things like this should be included? Listing every adapter in existence would be unwieldy, but some of these more unusual options might be a reason to prefer one system over another.

comment What benefit does Hasselblad have vs high-end Canon / Nikon?
@jrista Gotcha, my mistake. I did say "relatively simple" :), meaning more like the f/1.8 than the f/1.0 in these diagrams. The Hasselblad 80mm f/2.8 has 6 elements in 6 groups, which appears comparable to the Canon 50mm f/1.8.

comment What benefit does Hasselblad have vs high-end Canon / Nikon?
@jrista If an MF and an FF lens have the same resolution, measured in e.g lp/mm, the MF photo will have higher total resolution because the image is projected over more mm on the sensor. So yes, a larger sensor leads to higher system resolution all else equal. AFAIK, MF tends to sidestep optical aberrations by sticking to relatively simple optics - e.g. no f/1.4 lenses (for MF, f/2.8 is a quite fast normal prime) and no superzooms.

comment What product image catalog system do companies with thousands of products like Target or Macys use?
Canon has an article on image cataloguing - see page 3, where they discuss Reuters.

comment How can a high resolution camera matter when the output is low resolution?
Unfortunately I can only accept one answer. Matt Grum makes a credible argument that a small sensor, plus lighting and a bit of post processing, can replicate perhaps 95% of what we see in the Martin Schoeller pictures at web size (excluding the DoF effects). I think Michael Nielsen makes a credible argument that you might need better than typical APS-C system resolution to get to 100%. And Stan Rogers explains how we can recognize a large format camera even in web sized photos. I suggest you read them all :)

comment How can a high resolution camera matter when the output is low resolution?
@MichaelNielsen Agree that larger sensors have higher system resolution. Going by the DxOMark numbers, a low-end lens on a 16Mpx APS-C sensor gives no more than 4Mpx worth of detail. But 4Mpx of detail is still ~3x oversampling at web size, so I wouldn't expect much difference to an MF which might achieve ~6x. Maybe DxOMark overstates their "perceptual Mpx" number, I think it's based on MTF 20. So it's conceivable that a web size MF photo has MTF ~100, while the web size APS-C photo has less.

comment How can a high resolution camera matter when the output is low resolution?
Thanks, makes sense. On faking DoF, I think the 3D models used in computer graphics are advanced enough that it's mostly a matter of time. Maybe a future plugin for Lightroom/Photoshop 10? :)

comment How can a high resolution camera matter when the output is low resolution?
@MichaelNielsen But thanks for your examples. There are some differences left that I can't explain, but I don't think it falls under the header of "resolution". I could be wrong, of course :) - I'll need to do some experiments of my own.
