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

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

"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)

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?

The great think about chickadees is that you don't need hunting blinds to get close.... all you need are some sunflower seeds and a lens that focuses within half of an arm's length....

Ooooooh, these are really sweet :-) !!!

My previous camera, T1i, I didn't have any issues with any of my lenses. I'm betting it's me.

Probably, Canon lenses are usually adjusted just fine and f2.8 isn't as critical as 1.2. But if you can there's  peace of mind after making sure. Note that every camera body needs different afma adjustment values, so if your ti1 worked fine your 60d might not.

Last not least, afma is not a magic bullet. Newer cameras have different settings for the long and wide end of zooms, but it's still not sufficient since afma also changes with the subject *distance*. Afaik the newest Sigma lenses take this into account while Canon (still) doesn't.

Then again, I've worked both at Apple and at an embedded Linux startup, so it's possible that I'm just a bit biased against RTOSes.  :)

Interesting observations, though I (I never did rtos programing) like to add this theory: It's easier to debug and build a reliably system because if it works once then it'll work every time sine timing is fixed and this no problem. Do Nikon and/or Sony and other companies use multitasking non-rtos designs in their cameras?

Btw I don't find the Canon wifi implementation *that* horrible, video/wifi is bothersome but I don't do this, my main issue is that you cannot connect to a laptop in client mode but have to setup a virtual ap on the computer.

I hope they give the new flash head the same range of rotation as the 600EX-RT.  The head of the 430EX has a limited range of rotation.

There are only so many things how you can cripple a flash so people who don't need the "pro" features like ext. power supply and fast recycle time still can be upsold to the most expensive model. Imho Canon won't change a running system, and the extended flexibility of the head is one of the things that appeals to everyone.

The other thing the "small" flash probably won't have is the great 600rt usabilty simply because the flash is smaller, so if using one on-hotshoe or on-bracket flash the 600rt will still be better unless you perfer the in-camera menu (if you manage to find it).

I think Canon will NOT price the 4X0RT low enough that too many will be inclined to settle for that instead of another 600 (especially if refurbished).

On the other hand, their latest releases (70d, 16-35L-IS) were rather reasonably priced - so you never know, even with Canon :-p
