On article Now we know: Sony a9 is sharper than we thought (394 comments in total)

I usually look at the studio shots as a way to judge noise and various ISO settings, and to compare noise differences between camera bodies at the same ISO. The studio shot is very helpful for that purpose. But it doesn't seem like the best way to measure resolution. The do-over is interesting from a technical point of view. But for resolution, wouldn't a resolution test chart be better? It seems to me that it would be easier to focus accurately, and the results would be less subjective.

dr.noise: I have read that right, but not at the first try

Yes, the name does prompt a double-take. Like the reflexive association called forth by "iPad" when it was introduced, but more so.

I took the advice of many that filters can cause distortion & reflections and took my UVs off all my lenses. Then I chipped the front element of a $1200 lens and it cost $360 to replace the element. So now I'm thinking... $100 is cheap insurance. This article is very helpful, particularly with regard to the effectiveness of coatings, although I did wonder about what would happen at different wavelengths. But... THANK YOU!, even if it's not perfectly definitive.

On article Google will no longer develop Nik Collection (391 comments in total)

It's OK, folks -- it still will work. I got the Nik Collection for free free and use Silver Efex.

It seem unlikely that Adobe would change the way PS and Lightroom handles plug-ins, so the Nik apps will still be useful for a long time to come. They just won't get any better (or worse).

In the discussion of the barriers to switching, dPreview commented that going to an a9 was attractive and a lot less expensive for wedding photographers than it is for sports photographers. But all of your subsequent discussion has been focused (pun intended) on sports photographers.

I submit that there are a lot more weddings every week than there are newsworthy sports events, and therefore there are a lot more wedding photographers than sports photographers. If Sony picks off a substantial slice of wedding photographers, they'll probably be very happy to penetrate the sports photog market more slowly.

In which two weeks of the year does it not rain?

On article Throwback Thursday: Our first cameras (392 comments in total)

Balda 35 mm. possibly the Baldina model, a gift from my father around 1956. Traded up to a Kodak Retina Reflex in 1959.

Thanks, Broncolor!
There's a really good book on this subject - Light, Science & Magic" by Fil Hunter & others. The book includes a bit of theory along with diagrams of setups, but the practical examples in the videos are excellent.

On article Ask the staff: electronic or optical viewfinder? (890 comments in total)

I started taking photos when cameras were ALWAYS "on" - because they didn't have batteries. You just put the thing up to your eye. focused, composed, and took the picture. So it's maddening when I put the camera up to my eye and the viewfinder is black because the camera is off or the viewfinder has gone to sleep. The smaller size of EVF cameras plus all that info in the viewfinder offsets the black viewfinder issue. But I have missed some shots because of it.

On article Things we found at CP+ 2017 which had been cut in half (89 comments in total)

Ok, the sandwich has been cut in half, but not lengthwise, so it's not symmetrical. What good is that?

And the pickles haven't been cut at all.

Are the markings radioactive?
Just kidding....
Well....
Sort of.....
:-)

The web site says the paint is UV reactive, so perhaps the markings absorb ambient UV and reflect back (or glow) in the visible spectrum.

On article Throwback Thursday: Minolta's prosumer DiMAGE 7 (214 comments in total)

Thanks for rhe Throwback memory. I still have my 2003 model Dimage 7Hi. It was my first digital camera, and the manual zoom ring was excellent, especially for someone making a transition from 35mm film camera zooms. In decent light, the image quality was not bad - certainly capable of producing good 8x10 prints. I have one of those hanging on the wall at home. The range of external controls set a standard that insn't often matched today.

Great shots, helpful info. In addition to The Photographer's Ephemeris ("TPE), there's Photo Transit from the same publisher, which helps you determine how wide the field of view will be from a given lens, based on where you want to stand and where you subject is. Once you've identified the line along which you should stand in order to get the shot, Photo Transit helps you decide where to stand along that line and what lens to bring.

TPE made it possible to figure out that the Super Moon in October would appear to be rising just behind the two tallest buildings in Boston on a line that crossed the western edge of the Chestnut Hill Reservoir, about 3 miles to the west. Photo Transit made it possible to determine that a 300mm lens would be able to frame a shot from that location reasonably well.

Mike Sandman: What this illustrates isn't so much that we need photojournalists but that we need photographs to make events tangible. Think of the Zappruder movie of the assassination of President Kennedy, taken by an amateur. Or the smartphone videos of black men shot by police at traffic stops. The images are powerful, but they don't necessarily require a photojournalist. And we're getting more and more impactful photos from amateurs, now that so many people carry smartphones.

ewelch - No question - photojournalists make superb photos with high impact. Our local paper, the Boston Globe still employs an outstanding group of photographers who take great images. I do contend that "some bozo" with an iPhone can indeed take a photo that will have a global impact. I gave only two examples but there are many more. That's not meant to be a denigration of the importance of photojournalists, and i apologize if it looked that way. My point is that it's the picture that's important, not who takes it.

On article 2016 Roundup: Best Camera Drones Under $1500 (97 comments in total)

Excellent primer on the capabilities and characteristics to look for (at least for a new-to-drones photographer like me). I'm assuming there will be more drones with 1" sensors in the not-to-distant future, which makes things very interesting for a skills photographer. Thanks, and lets have more on these platforms, including in-depth reviews.
