alligator: How to do a +6EV push in ACR?

That's a very useful tip. I need to play with this sometime.

In reply to:

rkny: This place is hilarious. They post real world examples of cats and barns and people complain the pictures suck. They post professional post processed photos and people "well of course it looks great; it was shot by a pro and post processed".

News flash. Cat and barn pictures ALL suck. From EVERY camera. And if you spend $4K on a camera and don't spend time processing your RAWs, you just blew $4K.

If you can't look at unprocessed RAWs and see a camera's potential, or can't look at processed RAWs and see a camera's potential, you can't see, period. So stop slagging cameras that are over your budget, and way over your head.

This is hands down the best comment I've read here in a while and sums up dpreview readers well. I'd love to see what kind of images they produce in the small time constraints that the editors have with these cameras. I have one problem with your comment though. I don't think its really possible for cat pictures to suck. From any camera. Cats rock. Barns are kind of cool subjects too. But hey, what do I know after 8 years of shooting every day?

austin55: Since I have installed Windows 10 Pro upgrade, I have had absolutely -0- issues with the OS or with any software compatibility issues. I am about a week in... so far so good:) Everything seems snappier to open and my machine does not seem to be taxed at all. I use LRCC 2015 and PSCC 2015 daily.

Its a big problem. It doesn't seem video card related, more memory management related. Everything else is smooth sailing for me now. My video card drivers keep dumping at the login screen for no reason, but they will reload without a reboot. Oh well. I hardly reboot, so its hardly a problem to be honest. They should have worked out the major bugs first. A delay is better than total embarrassment. Always.

Fauler_Beamter: If the crippled RAW files concern you, let Sony know! Tell their Customer Support something like "Unless it has lossless RAW-Compression or uncompressed RAW, I won't buy it. Update your firmware and you've got me".

I've recently read an interview with some Sony Guy who basically said "If enough People want it, we'll deliver it."

Come on, Sony... unleash your Monster!

Thanks for the quote. Sony knows that it needs a more professional line IMO. I would expect to eventually see some kind of flagship beyond the A7. Just a guess though. It would be foolish for them to not address one of the ony real criticisms of their current line of cameras. I don't really like sony, but they are at least pushing technology forward at a fairly fast clip.

In reply to:

@ethanp99: i was exaggerating slightly. A lot of devices have 3gb now and last year 2gb was pretty standard. Memory is relatively cheap, so why not?

Lucky you. Is your kernel leaking RAM? I bet it is. Every windows 10 machine I have is doing that. Also my laptop dumps its video card drivers every time I reboot, forcing me to uninstall them and have system update reinstall them. My sound card didn't work until the first update pack because they had a broken mixer. When I try to boot safe mode, I just get a blinking screen. Also, startup recovery fails and says that it is not compatible!? Oh yeah and my windows 7 profile caused some weird bug that sent the data sharing service into a loop writing log files over and over again to my C drive. That one was really, really fun to figure out how to fix. I'm kind of sick of writing bug reports and asking questions in their forums. But yeah, no issues at all! Its just perfect!

I'm no sony fanboy, but they have stated in an interview that they are working on a solution to this problem.

So which is it? Sensor performance "is just as good" or a "trade off in some image quality for a sleeker device?"

In reply to:

munro harrap: The Static shots are dreadfull. The noise much greater than it should be. How long since anyone on Dpreview got hold of a Lunar Pro meter with incident light cone and went and stood facing the camera where the subject is.? Eh? Too Bl**** lazy!!

Plus stopping down a lot gets rubbish results on a 50MP sensor-more than f8 is trouble ( I notice it gets worse after f9 on a D800.)

Plus, another thing called reciprocity law failure, the bugbear of digital sensors.
Just as doubling the distance from a light source reduces the illumination level FOUR times (not to half what it was before) so too reducing the illumination levels by stopping down reduces the ability of the sensor to record such low light levels properly at all.
A theoretically perfect standard lens with no vignetting at any aperture will still produce darker and darker results as you stop down more and more. Try it!

Rinse and repeat!!

Oh I see, you set shadows +50. Still, you should use the curves box more. It gives you a lot more control IMO. I usually just set rough levels in the exposure box and then start tweaking the curve.

In reply to:

supersport100: nice! Pretty good!
But with the 5DsR you still end up capturing more detail, allowing more noise reduction.

"Well, with 50MP "fine detail" is defined differently. That's the point."

No. Its not. NR reduces resolving power on any camera.

Sensor manufacturers cheat and misrepresent the pixel count of their sensors? Hardly. Also you really take blacks to -100 and shadows to -50? talk about crushing all your shadow detail.

Incorrect. Digital has its own limitations when it comes to low light, but reciprocity failure is not one of them. Longer exposures increase noise from dark current, but that's about it.

On Canon warns about dangers of counterfeit camera gear article (153 comments in total)
In reply to:

samfan: I've read a story about a fake Canon flash about a year ago. The dude bought the flash online and one of the secondary features wasn't working properly, so he took it to a Canon dealer to check it out. They were trying to make the flash work for hours until finally they called a technician who eventually noticed some differences and figured out the flash was fake.

Scary.

On the other hand, there are rally good really cheap flashes available. I'd guess that if the makers of these fakes don't want to be found out immediately and hurt their business, I'd assume the insides of these fakes would be at least half-decent. But no guarantee of course... It can be the cheapest, most dangerous crap. Flashguns are dangerous stuff.

Manufacturers don't make much on the cameras themselves. They are hoping you buy accessories and lenses.

Everythingis1: Sooooo, what exactly are the dangers again?

Having had a lamp (and capacitor) on my Metz explode one night, I can say that none of the above will happen. It will just scare the crap out of you is all. The front plastic element kept any glass from leaving the flash. On a related note, does anyone want a broken metz 54mz? :)

Rick Knepper: Dear Mr. Maki. Please hear this [potential] customer. I was looking forward to my first light-weight, mirror-less, high-resolution FF camera. 42 MP isn't enough resolution. I see from your comments that 42 MPs work out well for video shooters but there are still some of us who shoot stills. I'd take 4k video with slightly less quality.

Two brands have surpassed you in sensor resolution, one with your own sensor and hopefully, Nikon will follow too. Also, I would have thought that 6-7 fps would have been doable in a 42 MP camera by now.

I am looking forward to the A7r SP (still picture).

By the way, I am eager to use your camera with native lenses.

42mp isnt enough? LOL. 42mp will outresolve nearly every FF lens made. If you need more resolution in a tangible way with bayer filtered sensors, you need to go to a larger format. The 5DS still not MF quality, and 35mm format will never catch up or equal MF. Feel free to disagree. BTW, I read your comment that you bought a 645. To be fair the resolution difference between 42mp and 50mp is pretty darn small. Like negligible really. I doubt the 10% difference is going to even be noticeable in real world use and in prints. I thought your original comment was a sarcastic joke or a troll to be honest.

In reply to:

zos xavius: This sensor looks like a decent improvement on recent 16mp BSI sensors of late. Less watercolor. Noise doesn't look horrible at 400 like the older sensors either. Its not fantastic or anything and I think a Pentax QS-1 would crush this on IQ, but hey for $175 its not bad at all.

Either way improvement is improvement and it is most welcome.

In reply to:

SwissRapha: HowaboutRAW, I think you are wrong here. Besides light transmission (T-stop), the lens does not impact the shot noise. How could it?
A better lens can not magically improve the shot noise of the incident light. Similarly, a bad lens (with the same T-stop) does not add shot noise.

BTW, what do you mean with a 'better lens'?

Howaboutraw: Do you even know what tstop is? Two different lenses rarely have identical Tstops. So, one lens is letting in more light than the other one. I have cheap primes with fast tstops that will crush newer, more expensive lenses on speed. What you are saying is fundamentally correct, but do you really know why? I guess myself and the other commenter were looking for you to clarify your statement somewhat. Fstop isn't the same as Tstop. Tstop is the real value of light transmitted. Fstop is determined by a mathematical formula. The two are not the same.
