I would like my sensor floating on a gel of intelligent microbes working in unison to achieve my vision.

On Panasonic Lumix DMC-LX100 First Impressions Review preview (1869 comments in total)
In reply to:

LarsLeibgott: I would very much like DPR to run a simple dust test on all these cameras. A Google search for the X100/X100s, RX100 line, Ricoh GR, X30, and so on down the line, reveals that sensor dust is a fairly serious problem (serious in relative terms, of course) with fixed lens compacts. I think it should be par for the course once DPR finish their hands on - f/16 at the sky and check for dust. These are cameras that have street photography very much in mind in terms of design, so it's not like shooting at f/11 and above is an abnormal condition. What do you say, DPR?

Sorry Richard, I was kidding. I guess I will have to get even less realistic next time. : ) Besides, can't Amazon just give you a billion cameras?

Clearly DPR needs to invent a Dust chamber that takes out the randomness of looking for dust spots. After each test, put each camera in the dust blaster (tm) and take a series of shots at different focal lengths. Then plot the dust on a graph. Extra points for doing several cameras from each manufacturer, like Lens Rentals does with lens testing.

mahonj: a: No-one drives around at night with their lights off - they drive around with them on.
Thus, you do not need this capability for automotive applications.

b: The image quality at +72db of gain is fairly awful - but what would you expect with +72 db gain in an image.

c: I think the news is the ability to do +72db if gain at all, or to get usefully clean images with (say) +36 db gain.

As far as I can see, this is about 2x as sensitive as normal sensors.

Which is something, but not driving cars around at night with the lights off.

Think back-up camera at night, among other uses.

Been enjoying this in a couple OS8 apps for a few days now. Procam works pretty well. It lets you lock focus on something and then slide the focus back and forth manually. Surprised to see this work on my 4s.

On BETASAMPLE_ISO400_DSCF0471 photo in dpreview review samples's photo gallery (3 comments in total)

While I don't care for how the bar shot of the horn players looks (yellow and plastic like) this one is very good. I assume this was shot at iso 400 to use the DR extending option. I like it.

phazelag: I admire Leica quality, but I would like to know exactly what I am getting for the additional money besides the name and dot. Any image quality or manufacturing differences?

Usually it records in dng, if that matters to you. The better warranty makes up for probably around $150 (guess for price of extended warranty). No raw difference other than the dng part.

Immediately noticed it because it's in red next to the message area. I don't really need to see all activity in threads I participate in, but perhaps direct replies to my comments would be good.

In reply to:

Wally626: Seems like the close shutter, open shutter, wait, use EFC might result in less vibration in images but it would seem to introduce more lag between shutter button push and the actual image being taken. Nice thing about EFC as used by Sony and I assume the other makers is that the delay between shutter press and image recording becomes very short.

No discernible lag. I use it by default on my EM1. Basically went from getting sharp images to getting razor sharp images handheld from 1/30-1/320, as if I were using a tripod. Pretty impressive for a firmware update.

I live in Alaska and wouldn't mind winning a trip to Alabama, at least in the winter or late fall.

Its black and white preset "deep blacks" looks pretty good at first glance.

On DSCF0813-ACR photo in dpreview review samples's photo gallery (1 comment in total)

This is an interesting image. It shows a nice and sharp trailer against the famous "mushy greens" that Adobe still produces. I've experimented a bit with some fuji raws and for the most part careful sharpening of the green areas and fine branches can help a lot. I think the detail is mostly still there.

In reply to:

OnCam: i must say the EVF is now as smooth as butter but i didnt see it unsatisfactory to start with. its still let down by shooting in daylight, i find myself covering the side of the camera with my left hand, a small eye cup would be fantastic & no a hat does not fix it for me.

Yes, that seems to be a problem with EVF's in general, that side light. I get the same problem with my Oly EM-1. I wear glasses and some kind of clip-on side shield would be perfect. They sell safety clip-ons, and perhaps with a little black paint... but for those without glasses a viewfinder cup that extended farther on one side might work well.

On Windows XP is dead. Long live Windows XP 'Bliss' article (123 comments in total)
In reply to:

Lenscraft: Every time I read comments on DPReview, I'm struck by how negative and angry that they seem. This doesn't only apply to the Canon vs. Nikon vs. Sony etc comments. As a response to this rather lovely scenic, I'm reading things like this:

"Always seemed blurry to me"

"Horrible image. To avoid as background at all costs."

"Proof, if it were needed, that even a good photographer can produce an utterly uninspiring image that looks fake."

Why are folks so negative? It's a pretty picture. Not my personal style, but that doesn't mean that I tear it down. Remember, there is a human being, a photographer like you, behind that image.

Unfortunately the Internet to many people is like a megaphone you hold up to your rear end.

On Adobe launches Lightroom for iPad post (131 comments in total)
In reply to:

mlewan: And what about importing RAW files on your iPad and using this app to transfer them to your Desktop via the cloud?

Might work, but too slowly for any large pile. It sounds like you can edit raws on the ipad, and then later load the raws on your computer (quickly, normal way) and any ipad edits will show up on your computer if you want.

Roger Engelken: So far, more than one hour trying to update the firmware and no luck. You just have to LOVE this technology. I certainly do not. Fortunately the camera still comes on and shows version 1.1.

Roger it was a slightly longer than average download for me, but still was done in about five minutes. It sounds like you are just trickling it in. Be careful. If you unplugged it after it finished downloading that's a bricked camera.

Certainly shows the potential, though I agree the editing needs work. I live a few miles from the glacier, and the caves have dramatically increased in popularity over the past couple years. Our photo group recently held a workshop at the glacier center and the one condition was that we show no photos of the ice caves. I think the forest service is worried about such heavy use and possible accidents. On a nice weekend day this winter you see big line of people making their way across the frozen lake.
