massimogori: Yes, amazing... example of journalism. Which Natural History museum? Imagine a newspaper writing an article about the murder of "John" rather than "Kennedy".

For those of us in England, it's obvious which museum it is, it's the Natural History Museum :)

For those of you from elsewhere, it's in London, England...

Jostian: Pricey... and this obsession with LED flashes, Xenon is the only way to go if a company is serious about the photographic capabilities of their phones! and Xenon is tougher on battery but seriously its not like you use the flash the whole day, come on Android, get serious with photography on your phones, give us a flash not a light!

Jostian; tricky because almost all the LEDs people are using now are being used in continuous rather than flash mode. Very few people are using decent LEDs as true "flashes".

In reality a bare LED die should be very similar in speed terms to a LASER which people use to provide millions of flashes per second - albeit at far lower power.

The only slight fly in the ointment for most white LEDs is that they're usually blue/UV chips with a white emitting phosphor - and that phosphor is going to be the limiting factor for most LED flash performance - in speed terms.

If I get some spare time, I'll have a play and see what I can put together. No promises though. I always seem to have more things to do than time to do them in... Also don't want to splat one of my nice LEDs ;)

Decent LED flash is more than a competitor for Xenon for devices this size.

The problem is that most cameraphones don't have a decent LED flash; they usually have a cheap and therefore poor quality LED flash.

LED can freeze motion just as well as Xenon *if* the LED is driven correctly.

Disappointed; I wanted the update to require a USB dock, dock ;)

Why is a Dalek like a photographer?

Because they both like standing around targets accidentally shooting one another ;)

On Canon EOS 7D Mark II: Real-world samples (beta) article (269 comments in total)
In reply to:

Lan: Please can you make the ACR conversions more apparent from the filenames?

Usually you give us IMG_0123_ACR, or IMG_0123; you haven't here (as far as I can see) so it's impossible to tell in the gallery which are ACR and which are JPEG SOOC in this set.

After looking at a couple of the JPEGs there's no point in looking at any more, as they show the excessively wide radius sharpening and excessive NR that the JPEG engine(ers) chose for all recent Canon cameras...

For those of us shooting RAW the ACR results are far more interesting (and relevant!). Please can you make them easier to locate?

LOL; that would do it! Thanks for clearing that up :)

OK, but then why do some of the shots have EXIF that says:
"Adobe Photoshop Camera Raw 8.6 (Macintosh)"?

7DII_beta_ISO200_030A9199 for example

On Olympus PEN E-PL7 First Impressions Review preview (466 comments in total)
In reply to:

Cipher: No flashing LEDs in the grip???? Come on Olympus...all the cool camera companies are doing it!

Please don't joke about things like The Cool LEDs in the Grip; they are inevitably scraping the forums and review threads for useful info about the next model's "must have" features like those Cool LEDs.

If we mention The Cool LEDs in the Grip too often we might get Cool LEDs in the Grip of the next camera. Those Cool LEDs are such a good idea afterall!

Sorry to mention The Cool LEDs in the Grip so many times in an Olympus thread; but I'm an evil Canon user ;)

Special edition out next month - a ruby instead of the missing traditional red dot, and a bargain at only twice the normal price.

Oh wait, this is Leica; sorry I was thinking of Hasselblad there for a moment ;)

BBViet: With a lens that big you can probably get 10 shots off before the AF motor sucks all the juice out of the battery.

Tomaz: That's what "glamour" photographers use isn't it?

In reply to:

The Name is Bond: Big Dynamic range? That's the only reason I didn't go Canon.

Install Magic Lantern, add the Dual-ISO module - now you'll have more DR than anything else (in a single shot) on the market at the moment. Not that the 5D3 lacks DR in normal mode anyway; it has more at the default settings than the D800 and the 7R...

adegroot: it's all grass mush here:

compare it to:

http://www.pbase.com/sigmadslr/image/102400630

Reprocessed jpegs at fault here?
or is camera and lens that bad?

Agree to a certain extent, but your sample image link doesn't work for me; try:
http://www.dpreview.com/galleries/reviewsamples/download/2986289

We're not comparing apples for apples here though. The Pbase shot was taken at f8 (almost certainly on a tripod) and is 2640px long edge; conversely the sample shot is at f6.3 (both lenses are wide open at f5.6), handheld and is 5472px.

The sample image size and the noise reduction are the problems.

That said, and I hope Jeff's cool with me borrowing his image in this example, here's his sample resized to the same dimensions as the original size on the pbase shot. Much better I'm sure you'll agree!

In reply to:

Philip Lanoue: I can do a reverse image search on many of the images from my wildlife photography blog and return pages of results. Lots of photos are being used in various ways all over the world, and I basically don't really mind or care.
It wouldn't matter anyway, what am I going to do? Sue some web site in China, Russia, or Saudi Arabia?
For those nice enough to ask, I always donate my photos and have done so many times over the years.
Earlier this year I donated a wood stork photo to the Chicago Field Museum that is part of their current exhibit.
I have been quite fortunate with my blog however, I have a nice solid group of honest, intelligent followers and visitors.

... and you posted a link to your blog here? Brave choice my friend, brave choice ;)

On Travel tripods: Comparing 5 aluminum kits article (110 comments in total)
In reply to:

Lan: Good comparison review!

Please can you do some vibration tests with a camera bag hung from the hook under the legs? Just one tripod would be interesting. I thought it would make things more steady, but I usually find that if there's more than a tiny draft, the bag starts swinging around - which I think might actually add extra vibration to the mix. So I'd be curious to see whether it does actually add vibration or not?

Also I'd find it helpful if you added a quick graphic to show how low the legs can go with the tripod flat down - a companion to the very useful maximum height graphic you already have!

LOL; I must say a bungee cord hadn't actually occurred to me. Not that I own any, but it's a good idea! Thx.

Canon: Please add support for previous cameras to DPP 4; we (users) have lots of existing images taken with earlier camera models too. At the very least you need to support the previous models in that range - i.e. 5D2, 1Ds3, 1D4. Ideally all Canon dSLRs.

I know I'm being a bit cheeky, but whilst we're at it, please could you add support for the DualISO CR2 files created with Magic Lantern? Pretty please?
