Neat, but... check local sources for up-to-date data. On the map, October 1 shows as past peak for NH & VT and at peak in Mass., but the southern third of NH & VT is typically at peak then, and not quite peak in most of Mass. (73 years of experience speaking here...). The web sites of local TV stations are often good sources for up-to-date info.

This was exactly my experience when I switched from Canon to Sony!

Average MTBF of 1.75 million hours = almost 200 years...

Ed Ingold: The ES-2 is just what the doctor ordered. I've been using an ES-1 with a 55/2.8 Micro-Nikkor and a Sony A7ii or A7Rii (42 MP) camera to copy up to 5 rolls per hour, with cleaning and sorting. The ES-2 has an adapter for film strips, which were nearly impossible with the ES-1 (I used an FH-2 adapter from an LS-4000).

It's easy to remove dust with a conductive brush (graphene) and a strong cross light (high intensity or LED). The results are grain-sharp, even with the 24 MP Sony A7ii.

Color negatives are always difficult to achieve good color balance, even with a dedicated scanner. The simplest way to remove the orange mask is with Photoshop Limits (ctl-L), optimizing each channel manually or automatically, then inverting (ctl-I).

The Nikon announcement made me think about buying a simple Nikon-Sony EF adapter and the recommended 60mm lens and using the ES-2 on my Sony alpha FF. The two posts about fixing the white balance of negatives are very helpful. Thanks to both of you for posting!

Pocket Light Meter, a free app on the Apple app store. Apologies for not being more complete in my OP.

OK, it was fun to rate the images, but... It's not called a blind test for nothing.
(1) results will vary depending on how your monitor is calibrated, and probably depending on your graphics card.
(2) I almost never shoot JPEGs, so it was fun but useless as a practical matter
(3) There are some really good points in the rest of the video, particularly in the concluding section, and that section is probably more useful in delineating these cameras than the blind test.
I'm a Sony a7RII shooter; formerly Canon. Scores: Nikon 29, Sony 25, Canon 17, for what it's worth, which is nothing. :-)

"The initial announcement was reportedly made by Krasnogorsk Mechanical Plant's Deputy Director General for Civilian Production and Consumer Goods, Igor Sergeyev, who revealed the plans via Moscow Region Radio 1."

This is a teaser for next season's Saturday Night Live, right?

misteryellow: Post hoc rationalization. He was just taking lots and lots of pictures and then selected the best ones (he said this), according to his taste. Just like other famous photographers.

Yes, but it's interesting to see which ones Cartier-Bresson selected. Whether he was making his selections intuitively or deliberately, his picks still do conform to classic rules. Interesting to have these explained through the lens of those rules (pun unintended), even if a few of the images have to be fitting to them aggressively.

jcb9001: How will photographers distinguish their work if you encourage them all to add the same tool to their kit?

I guess the irony is lost on the author of this article.

Anyway, drone footage with a stock music soundtrack is already banal.

"How will photographers distinguish their work if you encourage them all to add the same tool to their kit?"
We all have essentially the same tools - a camera body and one or more lenses. But each of us can produce unique work because of our unique ways of seeing the world. A drone takes the camera and lens up in the air. Each of us will use the infinity of vantage points in our own way, just like we do when we walk around.

"If you feel that your current camera is a better match for your needs and skills than the one it replaced, that's thanks to, not in spite of, the efforts of the marketing department.:

OK, it's the marketing folks who decided what features should go into the cameras for specific segment, but I think it's a bit much to give them credit for the leaps in functionality that we've benefited from. Let's remember the engineers, and the pressure of competition that have pushed the engineering staffs into a continual game if leapfrog.

And in the spirit of providing balance to Richard Butler's paean to marketing, I give you this Dilbert strip: http://dilbert.com/strip/2010-10-20. :-)

Scott Eaton: Doing something for 'free', be it uploading photographs or doing computer programming so that somebody else can make a commercial profit is wrong. I don't care how the author tries to spin it. Conventional economics dictates that this results in deflating a market, and deflation is wrong. I have no issue with distributing images for free for free purposes. Somebody is making $$$ somewhere from this.....just not the creator...and that's ethically wrong.

Giving away something free can be highly ethical depending on the context. I've given away the use of photos to a science museum, a charitable foundation, a community association, government agencies... and dPreview. Some of the photos had commercial potential. In theory, my gift potentially affected the income of professional photographers. Is that any different than doing volunteer work for a charity that would otherwise have to pay someone?

Mike Sandman: The drawings for curved sensors show an arc or parabola for the sensor, so at first glance, it looks like the the sensor is bent along only one axis. Doesn't a curved sensor have to be bent along both the horizontal and vertical axes, making it a three-dimensional paraboloid rather than a two-dimesional parabola?

Yes, an orthoganal vie would be confusing to some, but enlightening (pun intended ) to others. To each his or er own. :-)

The only surprise is that there was no discussion in the article or comments about the greater complexity of making a parabaloid - a sensor curved on both horizontal and vertical axes.

There are numerous illustrations on the web of paraboloids, so it's surprising to see a patent application that doesn't include a drawing of that sort, with light "rays" being shown by using an orthogonal view..

When I left the corporate world, I immediately switched to a Mac despite the cost and the Apples's walled garden. The Apple OS boots and wakes so much faster than Windows, and it's more stable. Speed and stability save time and frustration, and when you throw in Apple's superb customer support vs. Dell, the cost difference is justified - at least to me.

PhotoKhan: Next from Screw Bar: An app featuring a rotary dial that disables all other phone functions and requires you to actually do the semi-circular movements to dial a phone number.

There's a rotary dialer app already -- it's Rotary Dialer, on the Apple app store. I think it's been available since 2008. You can select from among several rotary dial "skins" including one from a classic black phone, and you can even get the dialer's sound effects.

On article Video: Removing a stuck lens filter... with a band saw (139 comments in total)

I've managed to loosen a stuck filter by wrapping a heavy rubber band around it and twisting. But this looks like the nuclear solution if nothing else works.

You can try this at home, folks, but after the cut, be sure to vacuum the stray metal shards away from the lens!

This is a significant update for A9 owners, and perhaps others. You may want to move this from "Latest Articles" over to the main news board on the home page.
