Photography Technique / Re: What can old-school photogs do better (or not)?
« on: December 13, 2014, 07:46:10 PM »
Composition.
Nope - definitely not an "old school" attribute/skill.
Nope.

There seems to be different ideas about the term "old-school". As I'm the op, here's my definite definition:

For me, "old-school" is not deprecative, but simply means that the skill could have been developed before the digital age. Such a skill is not necessarily outdated (like composition), though it might be for modern gear (like wet chemical developing). These skills are rivaled by what only we digital kids can do (like working with auto-iso).

Lenses / Re: 24-70 2.8L mark II image quality
« on: December 13, 2014, 05:37:58 PM »
Now while the center of the photo is hard to tell apart, as you go to the any of the corners of the photos, the 100mm is clearly the champ in that regard. I was wondering if the 24-70 II  is just not that great (contrary from what you hear) wide open and towards the corners, or if i have a defective one.

Having a sub-par 24-70L2 copy doesn't qualify as defective, but simply as sub-par and being unlucky. Or you are lucky and your 24-70L2 is fine, but your 100L is excellent and above the crowd.

Looking at the tdp test charts, the 24-70L2 should be about equal with the 100L if not a bit better (though not the same focal length) ... http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=674&Camera=453&Sample=0&FLI=0&API=0&LensComp=787&CameraComp=453&SampleComp=0&FLIComp=4&APIComp=0

... but there's a noticeably variation, read this: http://www.lensrentals.com/blog/2012/11/canon-24-70-mk-ii-variation

Having sampled only 2 copies doesn't mean you're bound to get a perfect one, so if you're unhappy you can keep trying. Imho for this price (standard zoom w/o IS, mind you) it has to have terrific iq.

Btw: Don't let yourself detained from inserting paragraphs in posts, it does improve the readability :->

I mean just look at the games they played with AutoISO. Utterly trivial code.
Trivial, yes, but it is a feature.[/quote]

Auto-ISO is still stupid or semi-broken on Canon:
  • Flash locked to 400
  • No way to set min. aperture in Tv
  • Crippled values for min. shutter in Av
  • No EC in M except for 1dx (dunno about new 7d2)

[Focus Stacking? Hmmm...How would you rate the results compared to proprietary software such as Helicon Focus?

Without a macro rail, they're equal. Helicon remote does with laptop tethering what ML can do anywhere, anytime. Of course you still need Helicon Focus or such to assemble the stack. I use it for mushroom photos - lay camera on something, shoot ~20 frames stack, get a beautiful pixel-sharp shot with bokeh behind.

In a nutshell, I'd like to read the bullet points from actual users here on the Forum on how (besides the few listed above) it would benefit a stills only shooter on a 5D3.

How about
  • full res silent pictures (w/o moving the mirror or shutter)
  • auto-ettr metering
  • focus stacking (for macro or landscape)
  • dual_iso for 14+ ev dynamic range
  • bulb timer (i.e. longer than 30sec)
  • handheld mlu (less shake w/o IS)
  • audio remote shot (clip your hands = shutter release)
  • trap focus (useful for handheld macro: focus = release)
  • key customization
  • "dot tune" for auto afma
  • raw histogram, raw zebras and focus peaking (in lv or picture review)
  • changing exposure in picture review
  • unlimited, automatic bracketing

Edit: added some points I forgot, just had a look at my camera.

The more I study Canon, the more I conclude that the problem is structural, rather than deliberate.  Judging from what I see on the outside, I suspect that each hardware product team has a group of software engineers that work on that product, probably in isolation.  Each product line probably has a separate code base that doesn't share much except the basic OS.

At least for the flash firmware part, that is (nearly) proven by ML's reverse engineering: It's plugged into the main firmware an only activated when the flash is used - unlike all other parts. This results in the annoying circumstance that you cannot program the flash via ML because the settings (the "prop") are not always present.

Food for thought, just in case anybody from Canon actually reads this thread.

Canon might have a certain structure, but their execs won't see it as a problem as long as their cameras sell just fine and their shareholders are happy. I'm 100% certain the Canon devs and sandwich execs are perfectly aware of what would need to be done to make progress ...

... but someone has to say "go!" and take the fall if regressions arise. In another thread, someone wrote that with Japanese companies the first responsibility is to allocate potential blame in advance, that's before actually doing anything.

I'm guessing you meant this in regards to people who ignore the EV level indicator and use a handheld meter, the Sunny-16 rule/Zone etc., or the histogram.

Right, good point there :-) ... this option is there to basically cover "everything else" that doesn't rely too much or not at all on the camera's metering. That's because the intention of the thread is to find the best metering mode when in a hurry w/o even time for ae lock.

And in full M mode even looking at the camera's metering, you still have to think more when bringing the little green pointer to the center line. :-p. Btw esp. on the 6d this procedure is a pita: In comparison to the 5d2 (same on 60d) the green info line below the frame is very small and very hard to read when in bright ambient.

Because you noticed, you're getting the "Schlaubi Schlumpf" (smart smurf) award of the thread :-> ... I don't know know if these popular comics have made their way over the great lake to marvel's superhero country.

Well it is "just the tip of the iceberg."

Fyi: ML development is about to hit the iceberg and sink to rock bottom. Alex, the main dev doing 90% of the work is busy atm, and there's only one other really insightful dev working on mlv and audio: https://bitbucket.org/hudson/magic-lantern/commits/all

There are a couple of people submitting patches now and then, but no one has the complete knowledge into the whole thing - remember it's about reverse-engineering Canon's software since our favorite manufacturer fails to release a sdk or even just the fw headers.

Hopefully the extra publicity will help Alex to continue development so we can look forward to a ML for the 7d2 and beyond.

Fortunately, ML is working fine just now on the supported cameras, but don't expect fast progress on the other great features in the queue until help turns up. And "help" means being a very good dev (few are), spending a lot of time on it and wrestle with other people when merging code.

So unless you're a coder at heart, this unpaid work is no fun at all. I stopped contributing when I felt stupid doing unpaid work on camera models I cannot afford, so now I'd rather just code for my personal ml build. But in general that's the great thing about it - it's open source, you're free to modify to it.

We are fortunate that ML development has been free and donation based to date.

To clarify: The ML project does *not* take donations, they ask you to donate to the eff instead: http://magiclantern.wikia.com/wiki/Donate

Alex has gotten the 5d3 and 60d as a donation, but he's content with that and doesn't want any more cameras (to work on). And the guy who got the 70d was never seen again after receiving it :-p

I am surprised that Canon hasn't taken these features to heart and started including them in current and future camera firmware.

I'm not surprised - support work would skyrocket and most users would be overwhelmed. ML is not for everyone, at the current state it isn't *supposed* to. But Canon has taken some features from ML into the 7d2: bulb timer and intervalometer.

I liked cat photo. But I made a poster of 1.2 meters of my cat and I saved a lot of money.
poor cat, don't you miss it now :-)

LOL :-)

Lighting / Re: Best way of setting up the lighting
« on: December 12, 2014, 06:15:29 AM »
I am asking for a common question but I truly need the exact answers from the experience photographers.

The reason for it being such a "common question" probably is that it's a contradiction in itself.

You can hardly expect "exact" answers from such a generalized question, giving away nothing at all about the specifics. Other people cannot do your work for you, even if there's plenty of helpful members around.

No you now understand what Gursky had in his mind when creating this picture? (Of course it is heavily edited/photoshopped to emphasize his message)

Ah right, so the intention was to confuse simple /me and my associations with the Rhein. Fair enough, and it certainly conveys a message of emptiness. However, I have a "been there, done that" feeling with the picture's (supposed) message, maybe that's why I missed it entirely.

As you might imagine I was never really one to interpret poems in school successfully :-) ... for your enjoyment, education and uplifting here's "The Dylan Painting" (for other samples see http://en.wikipedia.org/wiki/Monochrome_painting)

I'm wondering if the next firmware update will sort out some of these niggles
Hopefully
You guys are assuming the problems with some copies have nothing to do with hardware.  Since a replacement seems to fix it, that's unlikely.

Well, one reason more to upgrade to the 7d3 once it's there :-) ... it's not like hardware is flawless, Canon also missed some things on the 5d3 (af pts when tracking, broken write speed with sd).

I used to have the full set of every AutoCAD manual, the hardback period was gorgeous  :)

Right, were are good ol' times when ever self-respecting coder or it worker had a shelf of hardcover books like "Word for Windows 5.0" that aged like good wine and came in handy as paperweights :-) ... you could tell the expertise of someone just by checking his library. Nowadays, just like film we're haunted by ebooks and pdf, and all your knowledge is either in your head or on your hd :-o

Discovered to day that my new Tamron tele-converter does not work with my new 7D Mark II. It works fine on both my old 7D and on the 6D. I use it with the 70-300mm L F4-5.6 lens. Hope that a future firmware update allows me to use it.

A firmware upgrade of the *camera* to make it compatible with a 3rd party tc? Forget it. Same problems appeared on the 5d2 and 6d. You can try disabling afma, that helped on some camera bodies to prevent it from locking up.

Issues like this are only solved by the 3rd party, and if the item doesn't have a software update interface (like newer Yn flashes or Sigma lenses) you're hit for six. Probably they'll do a silent or official update of the tc sooner or later so you can sell on your then-old version to someone with an older camera.

I am going to have to re-read the AF system manual and see if the various setting have any impact.

Good idea, the detailed af settings are crucial when the af might be confused, either by objects getting in betweeen the camera and your subject, or when tracking losing sight of the tracked subject for some period.

I might add: In a two decades from now when we're all happy mirrorless shooters, you just install a software-addon module to your camera "snowflakes v2.3b" and all white points moving downwards are ignored :-)
