Post Processing / POLL: Do you need to fill the histogram in post?
« on: November 21, 2014, 01:44:58 PM »
I'm currently post-processing a bunch of wildlife shots (horses, my favorite subject) and would like to know how you feel a histogram should look like after postprocessing. I'm using ACR (Lightroom).

Personally, I try to adjust sliders and tone curve until I get whites and blacks somewhere, i.e. the shot fills the histogram with the main data neither to the very left or right. If I cannot manage that straight away, I usually resort to some local editing with ACR's tools like the brush.

At times, this can be a bit awkward if the scene was low-contrast in reality. The other problem is that if for example an animal's eye is the darkest part, it tends to cave in if I adjust black clipping accordingly and I need to do local editing (contrast) to make it look "alive" again.

Question: Am I painting myself into a corner with that approach, i.e. should I simply leave some part of the histogram empty? What's your take on "histogram after postprocessing"?

Note: I'm talking about natural scenes like wildlife or landscape, not about shots that are meant to be "artistic" from the start.

"Light-field photography is the future" - or is it?

Here are two reviews on the new Lytro Illum, still seem to be work in progress, but an interesting concept. And you can emulate a f1.0 lens :-)

What do you think: Is old-school single-dof photography doomed?

Post Processing / POLL: What picture styles do you use?
« on: November 11, 2014, 01:11:19 PM »
Even when shooting raw, the picstyle determines the preview result. Even if postprocessing from raw you have to set some camera calibration which includes camera emulation styles (at least with Adobe - though "Adobe Standard" is the default).

What picture style(s) do you use?
Anyone out there actually using Landscape for landscape and Portrait for Portrait?

Fyi: You can download several custom styles from http://www.canon.co.jp/imaging/picturestyle/

Business of Photography/Videography / Online rating/comment app/site?
« on: November 06, 2014, 02:33:44 PM »
I'm currently sorting through my heaps of wildlife shots and am writíng captions for them. As there are so many opinions as there are potential viewers, I have a couple of friends who are willing to give their personal rating for the shots, write comments or even text captions for them.

The problem: My current approach "create a web slideshow with numbered shots, then let the people write back via e-mail" has a lot of overhead and creates a lot of hassle for the volunteers.

The question: Is there some pic site where I can upload my shots that includes the option to rate the pictures online and write captions/comments for them? It doesn't need to have multi-user security, I can simply share my login.

I have my own website, so if there's some ready-made (sql/php) web app I can also simply use this - but writing my own interface with a cms like drupal is currently too time-consuming for me. A free or at least inexpensive solution is definitely preferred. If it has a nice interface, I could also use it to let clients chose the shots they like from pre-processed proofs.

Lighting / Yongnuo killed my batteries - warranty case?
« on: October 22, 2014, 09:53:52 AM »
I am a victim of the rather unreliable Yongnuo rt trigger which only performs at least so-so if you put a pair of spanking new, fully charged batteries into it.

But Yongnuo keeps surprising me, now the unit killed my batteries (two rather new Eneloops): I left them in for ~3 months because I didn't use the trigger anymore, and now they're stone dead and refuse to be recharged.

Questions: Does anyone know this behavior? Is this a warranty case (the unit itself works with another set of batteries)?

Thanks for any advice!

It has been mentioned in another thread about the $180 Yn clone, but imho this deserves a thread on its own: http://flashhavoc.com/shanny-flash-and-trigger-models/

Their first model "SN600SC" doesn't have rt built in, but you need an additional "SN-E3-MD" clip-on rt receiver - for slave flashes, I don't think this is too much of a problem. Like Yn, their sales site mentions they've got a "SN600EX-RT" in the queue which will be an integrated part.

Let's hope these things actually work, either there's some big catch here or otherwise these prices are outright crazy vs. Canon. However, as one victim of the unreliable Yn ST-E3-RT transmitter, I'll be very cautious esp. because the firmware seems to be still work in progress.

Lighting / POLL: What flash modes do you use?
« on: October 06, 2014, 02:16:48 PM »
Whenever I switch my 600rt flash from M to ETTL, the flash makes me cycle through these strange modes as there's no way (I know of) to disable them altogether. And I'm always wondering: How uses these anyway?

I hope a lot of people participate so we can get an impression if these exotic flash modes are dead weight (ext.whatever) or legacy modes (multi) that were useful before you could blend images in postprocessing.

Feel free to elaborate what your application is if you happen to use anything beyond ettl and m!

Don't like Canon's never ending firmware crippling game? Want 4k? Fyi: "AXIOM Beta: The first open digital cinema camera"...

Quote
The plan is to democratize camera technology and put the power back into the hands of the users. It is a self liberation by creating high end tools that we ourselves love to work with - fully independent of any of the big established camera corporations. The time has never been better for such a revolution than it is today!

I'd like to ask about input and inspiration about a problem that wildlife photogs are bound to face:

The heap of digital data grows and the *absolute* "good enough" threshold for most purposes seem to be reached - so it's getting harder to excel just by using the latest gear. On the other hand, the *relative* iq progresses, so your 18mp shots from now will be obsoleted by the 36mp shots from tomorrow if they basically look much alike.

How do you handle this problem, what's your idea of being different?

Even more expensive gear (200-400L...)? Even more remote shooting locations? Novel postprocessing styles? Or as an amateur, is it you simply don't care if your shot of a white-bellied heron looks exactly like every other as long as you know it's *your* shot with *you* being there?

Thanks for any inspiration, and if there are some good replies I'll share my approach :-)

Looking at some posts about dslr beginners reasoning what camera bodies and lenses to buy, I'm asking myself: Does it really matter if you start with a 7d1 vs. 7d2 or 5d2 vs. 5d3? Do you need a 16-35L/4 instead of a 17-40L/4? Or isn't it smarter to save the money, learn a lot and then buy the next better model in a couple of years?

I know for me, "just" buying a 60d was a smart choice - a 5d2 would have been wasted. With the €1500 saved back then, I now bought a 6d basically for "free" and can even profit from it as my skill is up to it by now.

What about you? If you would have had top gear right from day one, would have it been "worth it"?

Now we know we're all great photogs, well, at least we would be if our cameras would have more resolution and dynamic range :-p. But there is an infamous fix for the latter: bracket the scene, let loose the tonemapping app of your choice and dial everything to 11!

Looking at the neighboring "best hdr shots" thread, I've got the impression that a typical photog evolution seems to include loving surreal hdr shots with histogram inversion (i.e. parts that were darker in the original now is brigher). So here's your chance to show courage and let the world see your very early creations!

Note 1: Please only link/post your own shots and not those of others around CR, even if it is tempting :->

Note 2: No cheating, only real skeletons in your closet, unlike saying "My weaknesses are perfectionism and forgetting to cash in my overtime slips" in a job interview.

Photography Technique / Why 3:2 aspect ratio?
« on: September 26, 2014, 07:12:12 AM »
I understand the 3:2 aspect ratio is there because it's the legacy of the film days. I understand you're supposed to crop shots to this native ratio to imply "Well, that's straight out of camera, look what a great photog I am". As long as you don't crop 1:1 to make it appear even more medium format "pro". What I don't understand and was not able to find an explanation for:

Is there any inherent visual advantage of this 3:2 aspect ratio in relation to human vision?

Film makes use of much wider formats which seem to be more compatible with the way we see. This seems to make sense, because 3:2 landscape often feels a bit narrow, while esp. 3:2 portrait feels very tall and often awkward to me.

Thanks for any explanations from competent photogs around here!

Animal Kingdom / Rfp (request for pictures): remote wifi wildlife shots
« on: September 25, 2014, 03:20:06 AM »
Now I've got this high-tech 6d with wifi, but I don't use it because I can just put the sd card into my laptop. But there's this other use Canon actually propagates for wifi: remote wildlife shooting. But how practical is this approach in reality w/o the ability to re-frame the shot?

I'd be delighted if some people would post their results from wifi wildlife shots, no matter how terrific the result, to lend some inspiration to others. The camera to use would be 6d, 70d or any other model with wifi addon that enables remote shooting

Thanks for any samples (or links if I missed them)!

Photography Technique / Are you affected by the "pixel cropping" disease?
« on: September 19, 2014, 04:28:45 PM »
As I'm just postprocessing a bunch of shots, I'd like to ask around if I'm the only one experiencing this effect and if there's anything I can to to improve my editing speed:

I keep cropping the shot and rotating it until it suddenly "feels right". The problem is that I do this nearly pixel by pixel and 0.1 by 0.1 degree which takes a lot of time.

By now, I generally frame ok in the camera, but it always needs this tiny last, time consuming step to go from "could be nice" to "that's it, right there". In hindsight, this is often exactly one of the known suspects (golden ratio, thirds, ...) but I cannot predict exactly where to position it from the start.

Question: Am I over-doing it with finding the optimum crop? Or are you also investing a lot of time into this postprocessing step?

Thanks!

Photography Technique / Postprocessing brush instead of cto/ctb gel?
« on: September 19, 2014, 04:02:33 PM »
Good photogs will probably cringe at the mere though, but I dare to ask anyway :-o ...

... my enthusiasm for "correct" flash gelling has recently diminished a bit because for many scenes with defined edges or surfaces, correcting the white balance (temperature, tint) with the postprocessing tools in Lightroom work just fine. Plus often I need to tweak the local wb anyway since 1/4 or 1/2 cto doesn't necessarily hit the correct spot, and even "real" shadows are often too blue, so why bother at all with gels?

Am I missing something here, is postprocessing wb different than flash gelling? As far as I see it, the flash blocks some up some light frequencies and taking away these from the raw file should amount to the same thing?

Note that this only applies if you can quickly smudge over whole areas with a corrected wb, for fine foreground/background details gelling the flash is the work-saving way to go.
