On article How the 50mm lens became 'Normal' (63 comments in total)
In reply to:

BorisK1: "a 50-mm best approximates human" *perspective*, not "sight". A picture taken with a 50mm lens (or equivalent, if not shooting 35mm) covers roughly the same area within your field of vision as an 8x10" sheet of paper, held at an outstretched hand. Or a smartphone screen at a reading distance. If a "normal" portrait is viewed at this distance, the nose-to-ears proportion is neither compressed (as in telephoto) nor stretched (as in wide angle).

Perspective depends only on position relative to the subject, not the lens. If the photographer and subject maintain the same distance, the perspective of a 24mm lens is the same as a 50mm is the same as a 1000mm. Only the field of view changes.

Sky & Telescope magazine occasionally has articles on this kind of detective work, figuring out the when and where using astronomical information. It's pretty fascinating.

ozturert: When phones were reasonably priced, I also used to say "phone is always with me so I can buy a good phone with a good camera".
Now the high-end phones are so ridiculously expensive that you can buy a good phone and an excellent pocket size camera for the same price.
1000+ USD is way too much to pay for a good photo.

"But as a pocket computer WITH a phone, camera, calculator, hand-held game console, etc ... $1000 ain’t so bad."

I bought my current phone in 2015 (and it was a generation or two old then), used on Amazon for $220. It does all the things you listed above just fine. I can think of no good reason to pay $1000 for a phone, unless it was the only thing available and you had to have it RIGHT NOW.

On article Panasonic Lumix ZS200 sample gallery updated (46 comments in total)
In reply to:

keeponkeepingon: When I see a lot of these pictures my first thought is "I could have taken that with my iPhone". Perhaps out of the scope of a "sample gallery" but, given how the smartphones are decimating this segment it would be really cool to see some of these images side by side with a premium smartphone picture taken at the same place/time.

Perhaps instead of including such picts in the dedicated "sample gallery" you could include a separate gallery entitled "But is it better than a smartphone?" with a subset of the gallery containing smartphone pictures taken at the same time as the sample gallery.

Given it would take such a low level of effort I'm surprised this is not a standard feature of dpreviews coverage.

"When I see a lot of these pictures my first thought is "I could have taken that with my iPhone"."

When you scroll through the gallery, look at the photo details. The focal length ranges from 8.8 to 132mm. I don't know of any smartphone that does that.

Now I'm hungry for some Ivar's clam chowder. Too bad I'm in Oklahoma....

Personally I'm okay with the OOC jpegs, but the examples show what you can pull out of the shadows with RAW.

Tom K.: "Leaked product images show the Huawei P20 with three cameras vertically aligned on the device's back plate...."

No, the cameras are aligned horizontally.

They are horizontal if you hold the phone in landscape orientation, like most people hold a camera most of the time. (Also the text next to them is horizontal.) They are vertical if you hold the camera in portrait orientation, like the billions of lazy dopes who never, ever turn their cameras horizontal, even for video.

In reply to:

photophile: OK, I'm going to ask a dumb question. How do they get the photos to look so non-contrasty? There's hardly a shadow - the athletes are all somehow smoothly and evenly lit from all angles. Did the snow help diffuse the light?

A lot of the events are indoors or at night, where there are lights from all directions. And some outdoor events occur when it is overcast. And yes, when it's sunny there is a lot of reflection from the snow. I didn't really see anything unexpected as far as lighting.

Benjamin Kanarek: Surely you jest...$12,800 USD???? I am sure that my Zhongyi Mitakon Speedmaster 85mm f/1.2 lens can give it a serious run for the money. Oh, I paid around $800 for that lens. I have posted samples on DPreviews:

You just stated Leica's entire business case.

"...these days the iPhone 8 is all he brings. Find out what makes it 'good enough'."

Reduced expectations.

This can't have been shot with an iphone - it's not vertical!

In reply to:

Ellis Vener: I don’t care for the false nostalgia of the modern tintype movement. For me it is sort of like Ye Olde Renaissance Faire turkey legs for photographers, but I love the idea of a daylight studio and The way he designed and built it.

nos·tal·gia
noun

a sentimental longing or wistful affection for the past, typically for a period or place with happy personal associations.

You can't have true nostalgia for something you haven't experienced. Nobody living is a contemporary of wet plate photography, just as nobody today has lived through the Renaissance.

That said, it's an interesting artform.

On article How to photograph a stealth bomber over the Rose Bowl (12 comments in total)
In reply to:

Tom K.: When the B-2 was first rolled in 1988 out at the plant in Palmdale where it was built, the Air Force was careful to restrict lines of sight from the viewing stands to only the front of the airplane. However they had neglected to restrict the airspace above the plant so Aviation Week and Space Technology magazine rented a Cessna and got some shots looking straight down at the plane, revealing its unique planform.
http://aviationweek.com/blog/1988-b-2-stealth-unveiled

Really though, the shape of the B-2 was not a super-duper secret because the "star" on the ground in front of the plane, was a sly reveal made up of five B-2 shapes.
