dear photographers, i have 5D mark III and i want dot meterinng mode linked by AF point, like 1d4. i think it can make by firmware.
maybe we can do many posts, and canon will hear us

Probably possible, but I doubt Canon will add this to the 5DIII - it's among the relatively few features that distinguish the 5DIII from the 1D X (few, but important to some). If there's enough clamor, it might show up in the 5DIV.

I don't want to appear like an Adobe sales person, but Photoshop Lightroom for example is easily useable. You can start with changing some basic settings and then you can slowly work your way through the options. If post-processing is done in a reasonably subtle manner, I don't believe there is anything that can be said against it.

In many cases you need to do it anyway, for example in case your camera was not exactly level when you took a shot, but you are desperate for the shot to show a straight horizon or correct vertical lines. You can also correct your exposure to a certain degree, which is often quicker in post-processing than experimenting with different exposures or using bracketing, while you are shooting. Still, I feel to a certain extent it is a must have.

Just ordered 5D mkIII kit from Cardinal. They are getting lots of bodies tomorrow and a couple kits. Need to call unless you live near a store in PA. 215-855-4818. You can also shoot an email to Kurt, the owner, from their website. Real nice service and from what you can read on the web they have good reviews.

Looks like I have found an answer to my own question. Yes!!! with more functionality than I expected. From the Aquatech facebook page:
"Canon 5D MKIII conversion kits are now available direct through AquaTech for anyone using the CO-7 or DC5-V2 housings. Contact [email protected] to be directed to your nearest sales member."

Hensel, Elinchrom and Profoto also make ring flash heads (they cost substantially more than the PCB version, even for just the heads). The PCB is a monolight (self-contained/integrated power supply), whereas for many of the others the power pack and head are separate (Elinchrom offers both types, the Ranger series is a monolight, costs >3x the PCB). Paul C. Buff sells only direct, you can find all the others on B&H.

Re: Ukraine vs Ukrania

If "The Ukraine" was some area during the time of the USSR then they should have chosen a new name, at least for English speakers, when the country separated. It makes Ukraine sound like plane or plain and both of those are words with which you use "the".

Yes, they should have renamed it Hulkamania. No one would refer to it as "the Hulkamania".

Hi, I noticed that you have only ONE rest day at Namcha. Most people need more then one day to acclimatise. Please be careful, altitude sickness is not a joke!!!
Gokyo is infamous for altitude sickness, many people need to be helicoptered out because they are at risk of dying.

Anyway, the trek you are going to do is fantastic, I have done it three times and the views (photos) are excellent.

Think about your health, so you can enjoy

Thanks
Actually Namcha might be day 4 and 5 from website pre-set itinerary. The mountains are going nowhere ..for a while. If either of us don't get aclimatized, even with medication, there is plenty to do at lower elevations.
Glad to know you had a good time.
Thanks

If you have time to change lenses... use primes.

If you don't have time to change lenses... use a zoom.

I love my 100-400 mm and its old push-pull. I can't wait to try it on my 5d3. I use my 400 on BIFs and love it. You have to get used to having such a limited field of view but like most things, you learn to use it and wind up with great pictures.

Nice job. I want Canon to send me cameras to do a video....... and a tank. That way I can impress the girls like the guy in shot 2.

It's definitely all about impressing the ladies 8) haha.

We actually got to use the only fully functional Panzer Tank that exists in the United States. We got to fire it and everything

Absolutely awesome post. I'm currently at step 9 contemplating step 10

9. Realize 70-200 f/2.8 zoom makes my other lenses look bad. Get better zooms so I have the whole range from 16 to 200 covered with f/2.8 zooms ($3500).
10. Shoot with a $300 50mm prime and realize the image quality is better than my $1300 24-70 f/2.8 zoom. Plus the wide aperture lets me do all kinds of cool things. Plus, it’s 1/10th of the size. Also, about this time I realize I’ve actually become a decent photographer (priceless).

Wouldn't it mess things up if all of the less than zero noise was gone and you wanted to average frame right near black?

Click to expand...

I don't see why it would. Temporally variant noise is temporally variant whether or not its negative variation around an arbitrarily set 'black point' is clipped. You'd still get rid of it by image averaging.

Right at zero though say a pixel is, on different frames, value -5,-1,0,1,-2,0,-1,0,-1,-2,-4,1,1,-1,2,0,2,6,-3,3,0 and you avg that you get a different value then if you chop off all the negative results and avg over 0,0,0,0,0,1,1,1,2,2,6,3, you end up with a bit higher number and on avg with a million frames it would not avg to 0 but to a bit above I'd think. Whether that really matters a lot I don't know since I haven't done that sort of photography.

I pulled the trigger on the Adobe Creative Cloud for $50/month. It would take me at least 30 months (cheapest price point, CS5) at $50 to buy the suite so I figure I'm good plus I get the free upgrades and the bonus....? I don't pay the annual fee all at once, but at $50/month and collect interest on the balance.

I couldn't afford the 5d3 AND the price of just one program much less the entire suite to support as it was, so this is an excellent alternative and I GET IT ALL on the 10th!!!! Hopefully. Now I get CS6, Premiere Pro, and After Effects plus whatever else I have the time for. I figure in 30 months I will know one of them well.

Thanks Mt. Spokane and psolberg for the tips.

It's not the camera but the lens. You need a 200 f/2 for the portrait work sir.

I'm pretty sure he has that one

the 200 f2 is a monster of a lens.. Hey OP... do you have the 2.8 or the 2??

2.0 ;D

I will probably be shouted down but I would make all the buttons programable so that we could put what is most useful to us in the most useful places. My daughter is a professional photographer and has very small hands, its enough to cope with that the camera is for her very heavy, especially when equipped with the best glass and having the buttons fully programmable would make life much easier. I have to say it would also be helpful to me as it seems each time Canon bring out a new camera the buttons have moved and we start all over again.

*SHOUTS* I AGREE WITH YOU

Seriously, I don't see any reason why someone shouldn't be able to make their camera work how they want, except for the hassle of coding it...

*SHOUTS MORE*

I was happy when I first got my 7D and read through the manual:
"The DOF-Preview button is programmable!"
"Maybe that means I can also program the DOF-Preview function to a button in a more useful location than bottom-left-front?"

"wait, no I can't"

"awwwww FFFFFFFFFFUUUUUUUUUUUUUUUUU.................."

Because of the plateau at low ISO, I think the problem with the DR on the 5D3 comes because of the ADC

http://www.clarkvision.com/articles/digital.sensor.performance.summary/
"The dynamic range is often limited by the A/D converter and other electronics in the system, illustrated by the measured data falling below the model at lower ISOs."

He explicitly called out "other electronics" as well. The A/D converter is not always an integrated part of the sensor, however the sensor contains a significant amount of complex electronic elements that can create noise on a variety of levels. An off-die ADC must usually process more pixels than say an on-die CP-ADC, so it requires a higher clock, which has a greater potential to introduce its own electronic noise into output units. Once the ADC has actually converted an electron charge into an ADU, you lose the ability to eliminate those forms of nose...they are now essentially "baked into" the output units. Sony Exmor sensors eliminate several forms of ELECTRONIC noise in the sensor before they send the charge that represents any given pixel to the ADC (which, in the case of Exmor, is also on the sensor die). Sony has two advantages...they eliminate as much electronic noise as possible before ADC, and they have one ACD per pixel column, which gives then the added advantage of eliminating vertical FPN (which is actually apparent...the D800 only seems to exhibit horizontal FPN unless it is pushed by 10 stops or more, at which point it might finally start exhibiting full cross-hatch FPN).

Perspective distortion (seen with wide angles) and the related perspective compression (seen with telephoto lenses) are a property of the distance from the camera to the subject, independent of any geometric distortions introduced by the lens or camera angle relative to a vertical subject

Ah yes, you're right, I was indeed talking about keystoning, I didn't realize what perspective distortion actually means. "Correcting" actual perspective would indeed be tough - you'd need to make the background elements appear closer to the foreground. I could see doing that on a selective basis with cloning. I'd bet that some sort of plugin/filter could be made for that - perhaps requiring a user-created depth map to identify foreground/background.

I'm sure most of us wouldn't even be talking about this lens if Canon offered one. Even if it was $2000

Well, maybe *most* of us - but given the choice, with my budget I'd still get a 35L + Tamron 24-70is for the price of ob one Canon 24-70ii ...

You won't have to worry about storage by then, surely everything will just be pumped straight in to the cloud and sucked back out to view it all in a thousandth of a second

Click to expand...

I will never trust the cloud to store my photos. I won't put my photos in someone elses hands. I need to be responsible for my own stuff. That is the only way I know it's safe.

Click to expand...

While I would not simply dump it into any cloud I can assure you that the pros can keep your photos much safer than you can. I work in the business and the technology we employ to make sure your data is kept save is not affordable to the average joe. Of course that service comes at a price, but I would certainly trust my company much more to keep my photos safe than I could ever dream of.
Multiple DC locations equipped with the latest and most reliable backup hardware solutions, automatic duplication of any backup image into at least two locations. Fully automated validity check of the data with automated fail saves that will recreate a second copy should either one fail. And of course a migration path to make sure all data is moved onto the next hardware generation once it is being employed. (So no sad faces that there simply are no more 5 1/4" floppy drives out there)
Just like with photography it really depends on how much you are willing to pay. You can have your job being photographed by the guy with the disposable camera for free or pay a pro several thousand $ to make sure everything is perfect.

In 20 years time I would expect to have RAID datacenters with storage clouds that are self replicating you data over multiple locations. This being integrated right into your own devices to be viewed and worked with as you want. You wont have any more localized storage since this simply does not make sense when your dSLR will have full internet access to write any image you make right into your own private cloud space, instantly accessible to your laptop and all other devices for sharing or processing the image or even to integrate it right into your dA, Flicker or FB account.

The main reason I don't want to trust my stuff to someone else is you never know if they are gong to be in business tomorrow. Example, megaupload got shut down by the FBI out of nowhere. Even the biggest companies can go under. If i back my photos up to a blu-ray disk and stick it in a fireproof safe, I feel that might be a safer solution. But to each their own. If its affordable, doing both would certainly be best.

Damn that must have been a ton of work, talk about tedious. Pretty impressive, but incredibly time-consuming.

Drizzt321 · May 8, 2012

Looks like a small but noticeable improvement in sharpness/resolution on the D800e, nice. Maybe we'll find that as a trend going forward (in a few years when the next versions of XD come out) on Canon, or at least have it as an option. Or maybe it'll be an option (or the only option) for the rumored high MP FF Canon, whenever that might come out.

Browsing in the lens section of the Canon Refurb store today I noticed an interesting paradox.

Currently in the market for a teleconverter, the 1.4 II is listed at $349 in the Refurb outlet:

http://bit.ly/JLwsKz

However, the same product - brand new - can be had for less at B&H:

:-\

I was browsing various refurb camera bodies on there yesterday and was thinking to myself that the prices seemed generally higher across the board than they were even a couple of weeks ago. No reason for you to be drawn and quartered in this thread.
