Photography Technique / POLL: Do you wide-screen frame/crop?
« on: February 22, 2015, 06:10:22 AM »
I know I have inquired about this before, but I'm still undecided - sorry for that. So I'm asking the regular two contributors :-p to this subforum for another input, it's about framing again. The problem is that imho you have to have this in mind when shooting, and cannot just casually crop around later - or can you?

The one current reason is that I can only think of so many possibilities to squeeze horsies into the viewfinder. Some scenes simply only have boring grassland or sky on top/bottom, and some shots profit from the enhanced sense of direction or space with wide screen framing.

The other reason is that with current displays, 16:9 (with small borders on 16:10) is full-screen and doesn't waste as much space, it's not like we print all shots, do we? And viewing 2:3 on widescreen somehow looks stupid, like trying to put a film into a dslr.

The question are:
  • Is 16:9 too amateurish because all clients/sites expect with 2:3 framing? And real photogs traditionally frame for the native res of their big 100% ff viewfinders?
  • If you frame for wide-screen, do you do additional shots/composures or simply post-crop if it happens to work out (see poll)?

Thanks for any input or discussion on this, after accumulating some 2:3 horsie shots and learning the basics of pressing the shutter button I feel like I need to advance in one direction or another. I even did some pano stiches when the animals were so helpful not to move for some seconds :-)

Post Processing / How to effectively prune your wildlife shots?
« on: February 09, 2015, 12:59:38 PM »
Do you know a situation like the attached screenshot - you've got a screen full of rather (but not quite!) similar wildlife shots, are wondering however you'll be able to select just one?

I don't machinegun wildlife with 10+ fps, but I usually take more shots than strictly required esp. with f2.8 since my 6d's af system likes to screw up with these. Occasionally and miraculously, most of them are in focus, so I've got more than I bargained for. My steps are:

1. quickly check for total screw-ups in camera
2. with breeze browser: check composition and rate images
3. ditto: check good shots for pixel sharpness (using the embedded preview of the cr2)
4. in lightroom: check for duplicate or very similar shots, leave one of a series

I'd like to improve my speed for step 4, I need way too long for that because I cannot decide. Horse dreaming better than horse looking cute or horse looking interested? Harrrrrgggn....

How do you prune your wildlife series? Use an egg timer and force yourself to select one after the time is up? Stand up and view from a distance? Throw a dice? Ask your girlfriend/wife? ...?

Technical Support / Broken flash tube on 600ex - service costs?
« on: February 06, 2015, 02:15:50 AM »
After years of high-power hss, my 600ex broke down yesterday. I'm undecided if I should it have repaired or simply use it as a transmitter and get rid of my unreliable Yongnuo clone - depends on the price.

I had one flash repaired on warranty some time ago, and they replaced the whole head, zoom mechanism and all... sounds expensive, though I wasn't told the price. To get a price, I'd need to pay €20, they refuse to specifiy an estimated cost just like that over here.

Question: How much is a replacement of a broken tube in a Canon flash (600ex or otherwise)? Is there the option of only replacing the tube, or do they always replace the whole head, i.e. half of the flash?

Thanks, I'm undecided on this...

The 760d has very good specs, for Canon, that is. The camera body is much smaller than a xxd and most likely the firmware is crippled vs. the 70d - but still, it's a challenge.

+ AF 19-point cross-type. Center F2.8 corresponding dual cross (take that, 6d!)
+ RGB-IR photometry sensor. 63 zone TTL metering
- shutter 1/4000s, x-sync 1/200s
- 5fps
* newest dpaf and anti-flicker

Do you think the 70d will be the last xxd and in the future, there will just be "premium" Rebels and the semi-pro 7d2? Or is there still room for something in between?

Lenses / Advanced bokeh computation?
« on: February 04, 2015, 03:53:48 PM »
I was just reading about bokeh on wikipdia, and stumbled upon this sentence which unfortunately isn't qualified further (see

Some advanced digital cameras have bokeh features which take several images with different apertures and focuses and then manually compose them afterward to one image.

Can someone please explain which these "advanced digital cameras" might be and how the post-processing assembly works?

If I find this interesting, it isn't that difficult to write a Magic Lantern module which achieves the same thing with a click of a button - aperture bracketing and focus bracketing are both already included, they just need to be combined.

So the 5ds price is more than the initial 5d3 release, but not that much more.

Looking at the current 1dx/1dc price drops, Canon seems to suspect internal competition pressure as the 5ds has a unique qualities which might make it a "flagship" camera. Will you replace your old 1dx/5d3, or even upgrade from another, cheaper camera?

Let's get a quick survey, with usually ~100 people participating it mostly generates interesting results.

Lenses / POLL: The new 50mm will be...
« on: February 03, 2015, 01:58:46 PM »
At last, Canon is rumored to release a 50mm lens - could it be true? Cast your vote here and predict what max. open aperture it'll have and/or what legacy lens it will replace (if any)!

EOS Bodies / POLL: Is the new 50mp sensor Canon or Sony?
« on: February 02, 2015, 02:49:14 PM »
Some shady rumor site outside the only real CR has it that Sony has its evil hands in the creation of our new flagship:

What do you think? Vote here before the Fri 6th announcement and prove you're a Canon expert!

EOS Bodies / POLL: aa, or not to aa (5ds vs. 5dsr) ?
« on: January 30, 2015, 12:50:31 PM »
5Ds and 5Ds-R ... given the choice and let's think both models have the same price tag: Which one would you buy?

Background: For years we enthusiasts have been bashing Nikon for their trollish removal of the aa filter on the d800e, conning innocent users out of their money for moiré-ridden stills and videos. And now Canon follows suit!  If you've missed the discussion, here's a link with some information on the effects of the low pass filter by an expert:

EOS Bodies / POLL: How many mp do you want anyway?
« on: January 30, 2015, 12:40:13 PM »
Is Canon being driven into releasing a high-mp camera by Sonikon trolls, or is there an actual demand for more resolution even beyond what the competition delivers?

Vote here how much metapixies you require for your *general* shooting style - either for wall-sized prints, selling stock, zoooooooming in macro, cropping for reach, changing aspect ratio or just for showing off!

Note that the poll is not meant as "get it for free", but as in "pay more for money for it" and "trade-off resolution vs. noise" - so please consider for a moment or we we'd just get a "more is better" result.

Technical Support / Zoom ring on 17-40L becoming loose?
« on: January 20, 2015, 04:31:51 AM »
My trusty ol' 17-40L is developing a potential issue and I'd like some feedback if there is nothing to it or if it's a sign of impending doom(tm):

The zoom ring (the one towards the camera) has a bit of play, i.e. I have to turn it a bit before it grabs the actual focusing mechanism. I cannot remember anything special happening to the lens except my usual heavy duty outdoor usage.

Atm, this is not problem at all ... but if possible it would be nice to have experiences on how this will develop in the future - either stay this way, becoming a bit worse or completely breaking the lens requiring expensive servicing.

Thanks for any insight!

EOS Bodies - For Stills / POLL: Do you need 1/8000s shutter speed?
« on: January 06, 2015, 03:45:36 PM »
Some say a body with "just" 1/4ks is unusable and not a real man's camera. That made me set up this poll because I wonder how the general CR crowd feels about this.

My personal experience is that the missing 1/8ks hurts most for bracketing w/o a nd filter. Otherwise the stopping power isn't as significantly different unless shooting rockets in flight and it cannot be "fast enough". When in doubt I'd rather opt for one stop lower iso, esp. on crop.

What's your take? Exercise your right to vote now or forever hold your peace!

Business of Photography/Videography / (Why) do clients like high dr shots?
« on: December 19, 2014, 09:50:15 AM »
I just sold a couple of documentary shots, the client chose among a rather huge amount of my stock photos what the wild horsies I report on are up to round the year.

While tastes may vary and the client certainly didn't chose shots I like best (emotional content, uniqueness, whatever), I was surprised that nearly all choices were those of high-dr shots taken with Magic Lantern's dual iso, i.e. having 14+ stops of dynamic range.

Among the shots were these two below which were a pita to post-process, and I'm still not really happy. The scenes were noon and high dr, so I cannot really do anything about the "tonemapped" look, but it isn't - just plain Lightroom/ACR. It's only a choice how *how much* you raise shadows, not *if* ... sitting in indoors in winter it's hard to imagine summer can look that glaring and hard though.

Question:What's your experience - do clients like hdr-ish shots and why?

Currently, I'm not 100% happy with my 6d's metering, it seems to be a bit more dodgy than my old 60d... *but* that's because I don't use it properly as there's no metering mode I'd like. So please, no 6d vs. 5d3, dynamic range or Nikon vs. Canon discussion in this thread.

* What I *would* like is a dumb matrix metering, ignoring the af points and preventing clipping to an extent of my choice. Actually exactly what Magic Lantern's auto-ettr does, but that works only in live view

* What I *do* use is eval with center & recompose, but I am mostly too much in a wildlife-hurry or too lazy to use ae lock. The result is that in high contrast scenes (like with the sky in the picture) the exposure is kind of hit-and-miss, and my only way out is either press the ae lock on every metering or use full m.

So I'm really wondering about switching to another "bread and butter" metering mode, thus the question: How do you do it? What do you use?

EOS Bodies - For Stills / Which mf split screen for 5d2/6d?
« on: December 10, 2014, 05:46:02 AM »
A friend of mine is about to buy a mf screen for his 5d2 and asked me which to get. Does anyone have any experiences with the actual products and knows if it's "worth it" getting the expensive ones? How is the performance, i.e. drop in light and dodgy metering?

This seems to be the "better" one(?):

This is the cheaper one (yes, .de site, but you get the picture):°-für-Canon/dp/B003UUDL94/

Thanks for sharing any experiences!
