Please canon, charge me the additional $50 for comparable weather sealing!

They want you to charge *$5000* more for a 1d camera body :-p ... but still thanks to the competition, the 6d exists at all. Let's hope they continue to pressure Canon to do less crippling. On the other hand, why would they? Broken cameras due to humidity will earn Canon more $$$ due to "upgrade sales by planned obsolescence" than they loose from some free servicing under warranty.

But I admit the lack of proper sealing is on my short list of "Top Canon Annoyances", offering a $1600+ camera lacking some rubber rings is plain annoying, the same as not selling sealed ef-s lenses at all no matter the lens' price :-\

If any piece of electronics gets wet, don't seal it in a bag because that will keep the moisture in and worsen the problem. It's much better to find some shelter and let the camera dry out in circulating air.

Good idea, but in this case I was really caught outside by the thunderstorm, had only my water-proof bicycle bags with me and there was no shelter in sight :-\ ... I hope it won't happen again, at least I'll be quicker to stuff my camera away next time.

I haven't soaked my 6D yet (knock on wood), but I was told that 2 6D's and a 50D failed in wet/humid conditions during an insect macro-photography workshop in Belize last year, but 7D's and even some Rebels kept clicking.

Interesting, after my recent experience I believe it - and it's in line with my general assumption that Canon cut corners on the 6d wherever they could, except for the sensor that is. I hope more experiences turn up so we might know if the 6d is really more endangered than for example the 60d or even the 5d2.

How can one measure "weather sealing" and how can one test it?

As discussed over and over, you can't w/o a lot of money and creation of a new industry standard. That's why the only way to tell cameras apart is by collecting user experiences, hence this poll.

Afaik there is one thing that's different between camera models though: Some buttons are "sealed" with just some cheap foam, and some have rubber rings (or the like). Hard to tell since Canon doesn't give us any specs other than fancy "sealing" diagrams-

I treat all my cameras/lenses as being not weather sealed. I try to protect both the camera and lens so I don't have to find out the hard way what the marketing department meant by "weather sealing".

I also try to do that, but shooting outdoors I find this nearly impossible - sand and humidity always linger around the next corner. That's why I cannot tread my dslr as "unsealed" as my cheap mobile phone which breaks even if you put it into a damp pocket :-o

The day before yesterday I was surprised by a thunderstorm and shot with my 6d (and a sealed 70-300L lens) for about 5 minutes in the rain. I did my best to still protect the camera and wrapped some cloth around it, but some rain hit it. Afterwards I dried it with a towel as good as you can in a thunderstorm and stored in a waterproof bag.

Problem 1: The back buttons (Q/INFO) and the joystick buttons started malfunctioning after a very short time after the rain began. I have not experienced this behavior with my 60d.

Problem 2: Yesterday the camera broke down completely after some minutes of reviewing pictures - it's now at Canon service and I hope the warranty covers it. I had put it in a dry place over the previous night, but didn't use the "rice bag" method.

Question: What are your experiences with the 6d and wet conditions? Was I just very unlucky? I know the 6d sealing level is well below the 5d3 (which itself is way below a 1d), but after this experience I'll have to tread my 6d as I would a Rebel :-\

Technical Support / Re: Canon Repair Facility in Germany
« on: July 30, 2014, 10:01:50 AM »
is there anyone out there who can recommend a Canon repair facility in Germany? The are a few on Canon's website, only one is run by Canon. Any suggestions?

I always use Foto Maerz in Berlin because it's just around the corner from my home, but unlike Robert I cannot recommend them as far as my experiences go.

Their counter reception people are arrogant beyond belief and expect every piece of equipment handed to them to be in pristine condition (try that when being an outdoor photog). They have a hefty fee just for giving you a price estimation so you have to make a guess for yourself if the repair will be more than the lens' worth.

They also try their best no to be forthcoming with repair prices (I had a 100 non-L macro repaired, it broke down again, and they did their best to pin it on me - and there's really no way of proving different). Now that I have cps their attitude has gotten a bit better, but still be prepared to pay ~80€ just for them to pick up the screwdriver.

Marsu, I like the plugin idea - I think I've seen some photos like that out there.

It's also a good way to embed the headline and caption into the shots or into an added border.

As always, you can achieve the same result directly with exiftool and/or ImageMagick. Next to the commercial wrapper plugin I'm sure you'll find plenty of shell scripts or gui frontends around for various operating systems even if you don't use LR.

If I do, I might have to get with you on those former DDR sites.  I've seen some on EOSHD that look pretty interesting.

Be sure to contact me when you visit :-) ... I sometimes meet American tourists exploring these sites, there are whole small cities in the woods including cinemas, schools and nuclear bunkers. Even though they are mostly visible on google satellite these days, gps is always removed in forums like forum.hidden-places.de (being on topic) ... it's still not exactly legal to visit and you want to keep the best parts still hidden.

My main interest was to look for soviet propaganda, coming from western germany it's interesting to see how the russian soldiers saw the world and their enemy system. Surprise: soviet soldiers weren't blood sucking lunatics like my grandmother used to think, but decorated their schools with bees and flowers for their kids.

Since they always used their military newspaper as the background for their wallpapers, you can also look at their cartoons ("u.s. threatening the peaceful east with nuclear arms race") and propaganda photography ("praise the newest missile system defending us from the capitalist aggressors") from the 50s to their defeat, um, voluntary withdrawal 1990.

At worst, it would establish that I take pictures in these areas, something that would be easy enough to tell by the date I post the work and the locations that I put in the captions.


The frightening aspect is that people are not all that different, and by having some part of a personal profile (shopping, gps data in shots) there are only so many options left for the rest of your life. Being outdoor folk for example puts you in the potentially environmental critic faction, just like listening to the wrong kind of music or living in the wrong neighborhood. If you look at Snowden's documents, that's exactly how people are "scored" and classified as a potential threat, actions range from just being tracked on the net to being denied entry into some certain country to being hit with a missile. Ok, I'll leave it at that, it's CR after all - but it's part of the topic about gps metadata.

I'd like to say otherwise, but my life is pretty boring and predictable


All the easier to isolate the more "interesting" folk :-o ... that's why Phil Zimmerman already advised for *everybody* to use encryption because otherwise it's pretty clear who's got something to hide. But we might even end up there after all, there are initiatives for more "vanilla web traffic" encryption even w/o authentication just to prevent brute-force decryption with dedicated hardware aes breakers.

For a little perspective, I lived in Berlin during the USSR days and sadly, I see a lot of parallels with today's US government.


Right, I'm in Berlin since 10 years, and I have to say it gets more boring all the time. Good thing is that there are a lot of interesting ussr installations around the countryside still to visit and interesting photo opportunities there.

Back to EXIF - I'd like to add that I am often curious about other people's camera, lens, and exposure settings, and have learned a whole lot from that information.


I'd like to mention another possibility other than embeeding exif metadata in the tags where many people won't find it: Watermark the shots with the f/t/iso exposure for example with this LR plugin: http://www.photographers-toolbox.com/products/lrmogrify2.php

Same here on the GPS - I manually add the data to my photos - so I filter out my home and locations of rare species or Champion trees, but include it for everything else.

Without starting a political debate, I'd like to add the fact that innocently including gps information everywhere can be quickly added to your personal profile by the usual suspects.

I know that those who have nothing to hide have nothing to fear, but after Mr. Snowden's disclosures some non-US citizens could feel a bit picky about what they share. Having been a sys/db admin for some time, I have some general impression how much information you can harvest from piecing together tiny amounts of personal data. And when/where a user has been can be quickly connected to *other* people having been there - are you sure you weren't standing next to Mr. Bin Laden some time without knowing :-> ?

Ok, jokes aside, later proven innocent people in Germany have already been jailed for using their mobile phone in the wrong place (being triangulated by mobile phone cells) and having searched for the wrong keywords on the internet. For me, better be safe than sorry. But then again, *not* including gps information and *not* being trackable with a mobile phone all the time certainly is also suspicious. Oh well, interesting times :-o

Please feel free to add any thoughts in a reply.


Personally, I've waded through all possible exif/xmp/iptc/adobe tags as exported from LR and made a couple of exiftool scripts for different purposes. I only leave gps in for myself, for forums I leave in the basic exposure information for people to learn and compare, and for other web upload only the absolutely required tags like color space and image orientation.

Might seem a bit paranoid, but I don't think the regular viewer has to know that I'm using a Canon ff 6d with midrange L lenses or where exactly the shot was taken... the picture should speak for itself, being taken with a mobile phone or 1dx.

Btw there also is a commercial LR custom metadata removal plugin if you don't want to wrestle with the exiftool command line: http://regex.info/blog/lightroom-goodies/metadata-wrangler

Software & Accessories / Re: Noise reduction in Lightroom
« on: July 20, 2014, 02:23:44 PM »
If I process a RAW-Image in Lightroom, I will get more noise than from a in-camera-processed (or from DPP) image. Which settings do you recommend to get the same noise reduction in Lightroom like from Canon? And how much would you sharpen?


I won't go into nr/sharpening details, but there are good tutorials around and I'd advise you look at this (yes, it's commercial, but well worth it): http://www.lynda.com/Lightroom-tutorials/Noise-Reduction-Sharpening-Lightroom-Photoshop/142976-2.html

As for Lightroom, my advice is to use this plugin and figure out good settings with a tradeoff noise/detail you personally like and that's adequate for your purpose (screen, print, ...). The good thing about this plugin is that it takes into consideration if you have raised the exposure which a simple filter for iso values will miss: http://regex.info/blog/lightroom-goodies/bulk-develop

Photography Technique / Re: Help: lightning photography?
« on: July 18, 2014, 04:08:26 PM »
How do you like the tamron 150-600? I've owned a sigma 150-500 for a couple of years now, but am fiending over the additional 100mm the tammy offers...

I'd advice to check the reviews how long these zooms *actually* are, the nominal label doesn't mean much and esp. 3rd party manufacturers like to cheat here. Also the longer the lens gets, the less real life difference 100mm means unless you plan to multiply the effect with a tc.

Could anyone please let me know what sort of settings would be best on which camera and which lens, as we are scheduled for more lightning tonight.


There's a dedicated Magic Lantern motion detect module for this very purpose, see their site magiclantern.fm and google "magic lantern lighting" => results like http://www.dpreview.com/articles/7002555087/lightning-photography-with-magic-lantern

Canon General / Re: New Speedlite Coming? [CR2]
« on: July 17, 2014, 05:13:04 PM »
"Do not fire the modeling flash more than 10 consecutive times. If you fire the modeling flash 10 consecutive times, allow the Speedlite to rest for at least 10 min. to avoid overheating and damaging the flash head." Emphasis mine.

I dunno, if I keep pressing the modelling flash it simply stops working until the flash has cooled down. Am I using a special version of the 600rt or have I been just lucky so far. I never read manuals :-p and only touch them to come up with occasional smug comments :->

Which is why I think it won't be a 4X0RT.  Canon will keep the 600exRT as the entry fee if you want to play the integrated RT eTTL game. I'm going to put my money on a thoroughly uninteresting new flash.  Color me a skeptic.

Or it's going to be the 600rt replacement 666ex-rt with the new ettl-3 protocol:
* remote zoom
* second curtain remote
* battery indicator
* fec with wheel in m flash mode w/o button press (fw bug)
* one button group masks (feature on the yn st-e3 clone)

« on: July 17, 2014, 05:06:39 PM »
Me, I'd learn to get-it-right in camera.

In that case, you're probably not doing wildlife - most of the time, you cannot control the lighting and have only so many seconds to decide what the correct settings are. Me, I'd rather have a shot that local adjustments in postprocessing than no shot at all.

2. Global Contrast - again, this affects other adjustments - I typically add a touch to most shots, but more if there's flare, fog, or other things that have reduced contrast, unless that's the look I want

In LR, I raise global contrast only to remove haze, and then mostly with the brush. Just adding contrast doesn't look good to my eye, it's nice with curves and black/white clipping control.

5. Color - using HSL- if there is a color cast left after WB adjustments, I correct it here. 

That's interesting, I never tried that - what exact color casts do you target in hsl mode?

Yep, battery charge indicator would be useful. I suspect if Canon were truthful, they'd tell you that recycle time is the de facto battery indicator.

I have absolutely no clue why there is no battery meter - probably a technical problem because the power flux is so dynamic it's hard to get a good reading on the charge (and because all batteries have different discharge curves)?

Btw Canon *does* say the recycle time is the battery meter, as far as I remember it's there in the manual in the cfn description to show the slave "charge ready" status either by the red blinky or just the small light on the back.

An overheat warning might also be helpful to avoid damaging the flash.

Um, the flash get disabled if it's running too hot, doesn't it?
