Jimmy Dozer: Great. About 10 days ago, I sent in a Bowens/Calumet Monolight in to their repair facility. Now what?

Sadly, you are probably out of luck. You will be so far down the list of people the bankruptcy proceedings care about that you're probably best off just buying a replacement elsewhere.

bobbarber: Given: Sensor technology gets better every year.

A. Therefore, people will need larger sensor cameras in the future.

B. Therefore, people will need smaller sensor cameras in the future.

Looking back to the history of large format, medium format, and 35mm film cameras is cheating. The logic behind your choice must come from your own ideas.

Because... god forbid we learn from history?

I'm not going to either criticize or complain about those who are, but: wow, there is a reason that the one with the little kid with hands on the (relatively) huge dog is the lead photo for every story. That's a great photo that really makes you do a double-take.

On Nikon AF-S Nikkor 58mm f/1.4G review preview (402 comments in total)
In reply to:

Steve oliphant: Sorry to say but i tested this lens you should test it your self at 1.4 on a high contrast target like a focus cart with bright light on it ,there was way to much modulation transfer, the 50 1.8 G lens is a much better lens at 1.8 thats you best bet , the 58mm 1.4 is a real peace.... of doo.

That... makes no sense. The words you are using do not mean what you apparently think they mean.

In reply to:

ballwin12: I bet this is a Chinese company, Am I right? They do nothing, just want to steal patterns from others.

Well, maybe. Sakar is a small company headquartered in New Jersey. But they don't really actually design anything themselves; they basically license different brands (like Polaroid or Vivitar or Kodak, or even Hello Kitty) and attach them to Chinese imports.

Since it tends to be very low quality and *COMPLETELY* unsupported (try getting ahold of anyone at Sakar with a technical question, let alone a support request!), I'm pretty sympathetic to Nikon here.

On iPhone 5s Studio Comparison article (263 comments in total)
In reply to:

Frank_BR: Unbelievable, the Nokia Lumia 1020 outresolves almost all FF cameras except the Nikon D800! For example, if you compare the Nokia Lumia 1020 with the Canon 5D MkrIII you'll get the following numbers:

Nokia Lumia 1020: ~3600 LPH
Canon 5D MkrIII: ~3000 LPH

This result is even more surprising if you consider that the 85mm Canon lens was set to F/7.1, whereas the Lumia lens was wide open at F/2.2. That is, the Canon lens was operating at the optimum aperture regarding resolution, and the Lumia lens was using an aperture much more prone to degradation by optical aberrations. Even so, the Lumia won.

That's not to say it isn't impressive, of course!

I think you're making a false assumption about the "wide open" lens. Basically, all conventional wisdom is off the table here, since this lens doesn't stop down at all, controlling exposure only through digital ISO and shutter speed. That means it's optimized for the only aperture it has -- there really is no concept of "wide open" because there is nothing else.

In reply to:

fakuryu: Slow lenses? Make those lenses a f1.4 and what do you get? Yeah, bigger lenses.

@tkbslc I don't think you appreciate how small, light, and enjoyable these lenses are to use. I have a set of the older series, and I wouldn't trade 'em for a top-of-the line f/2.8 zoom at any price.

Well, maybe if the zoom were pricey enough to resell and buy the upgraded versions of these.

"Best" lenses as scored by easily-measurable characteristics only -- resolution, distortion, vignetting, transmission, chromatic aberration. Sure, those things are important, but it's a remarkably reductionist way of ranking artistic tools.

In reply to:

Nathaniel George Weir: Canon makes better lenses than Nikon, and if you don't agree with me, then check out SLRGear.com and the Digital Picture's "ISO crops" and then compare Canon and Nikon glass. You shall see that Canon lenses are consistently sharper and have less CA.

Sharpness and CA are boring. They are only fixated on as the most important aspects of lens design because they are so easily measured, and the techie population which makes up the core audience of online photo sites gravitates to "serious" and "scientific" reviews based around measurable numbers — never mind that aspects which are not so easily measured are often more interesting and more important.

On Leica announces X Vario zoom compact with APS-C sensor news story (757 comments in total)

Sooo, if we use the 1.6x linear difference in sensor size between this and the Canon G1 X to compare apertures, we get:

Leica: f/3.5-f/6.4
Canon G1 X in equivalent terms: f/4.7-f/9.8

As we all know from so much forum arguing, this equivalence is right-on for depth of field effects assuming same-size prints, *and* roughly for noise performance because of the inherent advantage of the larger sensor.

That's last year's competition, I know, but it does look like the Leica isn't entirely wasting the larger sensor.

Really? The line between okay and "utterly useless" is in that one-third of a stop?

It's also a class of digital files. You might not like it, but there it is.

In reply to:

shakyone: I really enjoyed the article. I'm a long time GIMP user, and it does what I need, when I need to get my hands dirty.

Not meant to argue with the author, but it is worth knowing, GIMP v2.10 will have 16/32 Bit color support. It is working in the development version
(http://www.gimpusers.com/news/00422-16-bit-goat-invasion-ready)

You can get GIMP for OSX at: http://gimp.lisanet.de/Website/Download.html

I'm glad to see DPReview finally acknowledge GIMP as a usable alternative. It much more capable than most realize.

It has a steep learning curve, but so does Photoshop. If you are starting from ground zero, there are plenty of tutorials on the main website and on the web to get you going. There is also a great book by Akkana Peck about how to use it. It is a fantastic reference for novice advanced photo editors.

I like many of the other proposed options.

One more suggstion: A free RAW editor to consider is RawTherapee.

@HowaboutRAW 2.10 isn't 3.0 -- the dot isn't a decimal point.

lspoden: This will cost the average photographer that uses Lightroom and Photoshop around $600 over five years. This is a total money grab by Adobe. They have no competition so they can get away with it.

Here is my analysis: http://www.lenspoden.com/photo-topics/

@CFynn That is typical for a software company, and actually very high for companies overall. The money is _definitely_ "going there".

How does Corel manage it? Well, aside from repeatedly going bankrupt, they've made a lot of acquisitions over the years.

TFD: Everyone thinks the cloud is a great, no one knows what it is. I would not want to get tied into this one. I would guess that the performance would be less than exciting.

Personally I am now using Corel Paint Shop Pro, it as a better interface than Adobe and it does everything I need for about $100.

Here, they're just using the word "cloud" to mean "subscription software", and they're only using it because it's a more-palatable buzzword. The software is still actually installed locally, so performance isn't an issue.

Here is my analysis: http://www.lenspoden.com/photo-topics/

$600 over five years? So, literally, a third of a dollar a day? Really, cry me a river here.

Adobe's R&D takes money, and with digital goods a subscription model makes more sense than pretending you're selling an object.

If you would prefer something else, there *is* competition in for example GIMP, which has a recently reworked user-interface and will shortly gain full 16-bit support.

Sure, it's a little bit behind in some of the greatest cool features in Photoshop — but that is _literally_ the difference that R&D makes.
