This was very interesting. As primarily a portrait and landscape photographer, I approach focal lengths differently. For instance, I tend to think of how focal length (expressed as camera-subject distance) exaggerates or diminishes facial features. I must admit, I rarely think about the emotional impact, which is the main point here. Thanks.

The light does not halve when you double the distance. It is cut by 75%. That's what the "square:" part of the inverse square law means and that's why doubling the distance means a difference of two stops.

Jim Salvas: I saw a guy shooting with one of these at an outdoor concert in a nearby park a couple of weeks ago. I recognized the camera and when I asked about it, found out he had been using it to shoot video and stills for a real estate client across the street. He let me handle it for a bit and it was hard to believe I was shooting with a MF camera.

His major praise for the camera was the dynamic range he was getting, claiming 15+ stops even in video.

Jordan, I guess when you lay out $10,000 for a camera that will impress clients, you can convince yourself, too. ;-)

I've aways liked playing around with pinhole photography and its unique properties. In fact, I developed and marketed the first laser cut pinhole accessories in the early 80s (distribution and advertising costs killed me in those pre-internet days).

Anyway, its fun to play around with the unlimited DOF of a pinhole and the absence of distortion. Both of these make pinholes very interesting for 3D photos, allowing you to get everything in the same relative degree of focus, while making for perfect registration of the two images.

In retrospect, I should have figured out a way to make each of my laser pinholes cost $69. At that price, I might have broken even.

Jim Salvas: It's a pretty old idea, which was popularized years ago for shooting headshots in the open door of a garage. I can't find the link now, but a successful LA headshot photographer had a nice video on this. I've used the idea a few times when I needed a quick headshot.

This was a quickie garage headshot. I didn't edit the catchlight here, but I often do in many cases, even when using studio lights (I don't like the donut highlight from a beauty dish).

Wildbegonia: Now this is a real oldie one! Congrats!

Thanks. It's my favorite photo from my time in Vietnam.

I can see this for online retailers who have a lot of products, but not so many that it wouldn't pay to have their own photo setup. It won't work for almost all one-off items or eBay sellers, since the shipping and handling costs and delays will kill that. Nor will sellers of expensive items want to insure and ship their stuff back and forth. Somewhere in there is the Goldilocks customer, who has just enough of the right sort of products, but not too much.

On challenge Slow it down (17 comments in total)
In reply to:

TMC_SF: 83% of submissions (yes, I'm Obsessive) violated the "Less than 1 second" rule. There are some very beautiful images, but what is the point of following the rules if almost nobody else does?

The rules were obviously stated wrong. The host should have fixed this oversight.

On photo Ghost Ship in the Slow it down challenge (6 comments in total)

As far as I'm concerned, this is the winning shot in this stupidly confusing challenge. Most sensible people interpreted this as a challenge for slow shutter speeds. About five people figured it was for speeds of 1 second or faster -- which is ridiculous - - and then sandbagged everyone else.

Congratulations on having the best photo in the competition. I withdrew mine in protest.

In reply to:

David Omara: Worthy winner that complied with the rule of 1 second and UNDER. (like the rest of the top 3). 😉

It appears most of us interpreted the rule logically, instead of literally. A "slow it down" competition that allowed only shutter speeds or 1 second and under (that is, faster) would be sort of ridiculous, as that would allow for speeds of 1/16000 or faster. Therefore, most of us assumed this was for slow shutter speeds and got dinged for it by the literalists. The 4th place photo is great, but still got 5 votes of 0.5. Sorry, but that's stupid.

My lottery camera. It will likely sit unused, in my lottery car, parked next to my lottery yacht. I may let my staff photographer use it.

My suggestion is a Mamiya twin lens, such as the C33. Sharp interchangeable lenses, leaf shutter, great 6x6 negs.

While I commend DxO for keeping Nik alive, I'd like to see more substantial improvements before I throw more money at it. And, yes, I'm one who bought the collection about a year before Google made it free and made me feel like a fool. Some of the U Point technology still lives at Google, in the form of Snapseed, which is still my favorite quick-edit tool on mobile.

I generally don't read the reviews for the 1" and smaller sensor cameras. Do they all tell you that the camera is good, but a larger m43 sensor woud be better?

Jim Salvas: A pixel width of around 8,000 on a micro four thirds sensor would mean a new, higher resolution sensor and we've heard nothing about that.

I know. But to my knowledge, nobody has announced a 4/3 sensor which will do that. To me, that would be bigger news than the camera.

We had a very similar situation in local politics a few years ago and the judgment was for the photographer and the opposing party paid. In that case, there was even more manipulation of the photo, but the judge rightly concluded that it was not enough to qualify as fair use. The judge in this case is flat wrong.

FuhTeng: Very cool video. Fun to use PhotoPills and all its abilities.

Agree. I got it a couple of months ago for an assignment. The client wanted a picture of a sunrise at his home. I used PhotoPills to figure out where the sun would rise over a fountain in front of the house and where to put the camera to catch that alignment. I lucked out on the weather and got the shot.
