Canon General / Re: RIP Leonard Nimoy
« on: Today at 02:00:33 PM »
Leonard Nimoy passed away today.

Oh my, all I need to know about life I learned from Star Trek! I feel kind of old now that my childhood idols start passing away. But it's no surprise, in his recent short appearance on the new Star Trek movies he already looked very much past his prime. Thanks for letting us know.

Btw: Let's not forget Nimoy redeemed the Star Trek universe from Shatner as a singer!

Lenses / Re: APS-C 60mm or 100mm macro lens?

Given that IS is useless at 1:1

... agreed (though others don't) ...

and that AF is also useless at close focus.

... but I definitely agree here. Sure enough the keeper rate is very low with a very thin dof, but for example with shooting butterfly macros (i.e. really near or at 1:1) doing ~5 quick attempts to nail the focus it usually works.

I have no idea how I'd do that with manual focus because if you're in the real outdoors lying on the ground with a live animal, it's about speed. Esp. with the very small viewfinder of a crop camera, mf would be really tricky.

EOS Bodies / Re: EOS 6D Mark II to Move Upmarket? [CR1]
« on: February 26, 2015, 10:01:53 PM »
If a 5D Mark IV doesn't happen, then the 6D2 is going to be a 2nd generation 5D3.


The Canon 6D MKII as a minimum will need to have more AF points at least 19 and likely more all cross type, it will need class leading low light capabilities as the original did, the shutter life should move to 150,000

... no way!  Canon will make sure there is a healthy difference between 5d and 6d and that the cheap model is *not* "good enough" for semi-pro shooting (i.e. shutter life) or tracking. Just putting 4k into the 5d4 won't manage that, they still have to down-cripple the 6d a lot either via hardware (af points) or firmware. Of course if the 5d4 has a serious sensor upgrade, they could be a bit more lenient with the 6d2.

For every customer that buys a €2000 6d2 instead of a €3500 5d4 Canon looses a lot of money (esp. if the 6d is cheap to produce with legacy parts). The 6d isn't there to because Canon intends to have a nice ff system option for the masses, but simply because they have to make sure people don't jump ship to the Nikon d6x0.

Personally, I don't see a 6d2 at all for some time as long as they make money from the 6d1 - question is how cheap to produce the 6d1 is and how long they can live with dropping prices.

Technical Support / Re: My Canon 60D does not power up with a battery in it
« on: February 25, 2015, 02:55:59 PM »
I do not know where to go with this and the camera is only 4-5 years old.

The age doesn't mean anything, but the intensity of usage and circumstances. And yes, these electronics break suddenly, it's not like there's an early warning like a slowly failing shutter mechanism.

Did the camera get wet (it's the #1 cause of havoc)? Otherwise make sure the battery door closes properly, as you probably know *inserting* the battery does nothing, it's closing the door that enables the camera to power up.

You are limited to the 8-bit codec Canon uses but it isn't bad if you get the exposure right.

In that case, do hope Magic Lantern at last makes it to the 70d so you can shoot 14bit raw with full dynamic range :-) ... I don't know how fast the sd card speed of the 70d is though. But the good people owning a 70d are frantic for an ML release as the 70d with its swivel screeen & dpaf seems to be a nice video setup in that price range.

Sounds like a nightmare to me to sort out all those captures  afterwards.

I'm sure someone smart will figure out an algorithm to do it for you, at least for the bulk. Magic Lantern already has some of it, actually such an algorithm is built into Canon's digic chips right now (yes!) - for their burst silent shooting, they let the digic compute a "in-focus" quality scale and automatically select the best ones. And if you only need one shot where the ball hits the soccer player's head, well, that's even easier to select.

But I sympathize with your reluctance to imagine possibilities of new tech, that's makes the CR people what it are :->

I rarely spray and pray. And even then 5-6 fps are plenty for my usage.

Maybe so, but obviously the high-fps 1d cameras meet a demand. My 120fps example might be over the top as the raw data rates would be ridiculously high, but let's say 15fps 4k raw shooting - I'm positive it'll sell like hotcakes.

And you have to draw a line in the sand somewhere.

Sure, and for me the differentiation between LR and PS is that the latter is designed for photo compositing and layering to support a full-fledged dtp app like Indesign or do posters on its own complete with typography.

I find that an extended heal by canvas extension is absolutely in the scope of LR, and as argued being to forced to throw away image data just because you rotate the image can be improved for sure.

But I don't see criticizing it as being a lousy program for doing something it was never designed to do.

Did I ever do that? I think LR is one ever the best programs ever, I have no idea what I'd do without the speed, bulk editing and cataloging. The latest healing features in LR5 make it even better as I often have to replace small parts like a leaf of grass that caught too much flash light, and that was a pain with LR4's circular-only healing. Ends Adobe commercial :-)

I don't feel the need for more pixels, but wouldn't want less; and I use my video camera for capturing video so I don't need 4k video.

As far as I understand it, the attractiveness of 4k for still shooters is grabbing hi-res frames off the sensor w/o the need to move the mirror. How about 120fps 8mp raw shooting to capture the moment?

Canvas extension would be a nice feature!

Btw the lack of canvas extension results in a really strange behaviors: If you do some aspect ratio or perspective correction with automatic "upright" or with the manual lens correction sliders, you get white parts on the edges of the frame you cannot touch or fill and have to crop away. Doh.

EOS Bodies / Re: 6D firmware 1.1.6 exposure issue
« on: February 25, 2015, 12:16:29 AM »
So, I've got 1.1.3 as factory installed. Is there a good reason to upgrade? Any major improvements in function?

Imho the autofocus fix can be considered "major", but you currently cannot run Magic Lantern with 1.1.6 (they're on it though and it'll be ready in some weeks).

What additional detail is visible is so because there is less noise, there is no more spatial resolution.

I'm nowhere near promoting this technique, but imho in theory upscaling *can* result in more res on select images.

OnOne has pioneered this with their "genuine fractals" PS plugin, which was the most stupid name ever because no one understood what it did. Afaik it's part of their plugin suite now. The idea - to my understanding - is smart extrapolating, i.e. not straight lines but more "natural" patterns, too. When I tried it it worked, and while I'm not a big fan of too much image cooking beats any other upscaling method.

So even if this super-resolution doesn't get you terrapixel shots, it's probably nice to have as an additional method in the tool bag if a shot doesn't have enough metapixies. At least, it seems it cannot make the image worse :->

How is it not already?  Because it can't do layers?  Or pixel-level editing?

My one major grief is that you cannot extend the canvas, i.e. on rotate there's no way to heal-fill an area, you *have* to delete the part that is rotated out of the rectangle. The same goes for fixing a too tight framing. This is stupid because after a trip to a pixel editing app (converting raw->tiff, doh) and adding some space around the shot LR's heal/clone brush works just fine for this purpose.

Yes and reading a link like that illustrates the near certain fact that you don't actually do it, or, if you do, that you don't analyze the actual output.

Interesting, I didn't know this technique. I don't understand why you state that him reading means he doesn't do it? The article is rather conservative on what to expect concerning detail and mentions noise reduction (Canon Rebel multishot, here we come) and moiré elimination.

Now I don’t want to get your hopes too high: the difference in perceived resolution between a 24 megapixel image and a 94 megapixel image is actually less drastic than you might think. Even though it’s nearly four times as large, the increase in resolution will only be apparent in the areas of the image with the finest detail. As a result, the technique here only shows tangible returns on very highly detailed scenes. This is a pixel peeper’s method.  The benefits are very real, but the results might be less drastic than numbers would initially indicate.

... and my favorite line ...

But let’s make a huge image just because we can

Btw - is there a ready-made photoshop action for this rather than doing it all manually?

Photography Technique / Re: What is your keeper rate?
« on: February 24, 2015, 09:34:47 AM »
so if you are shooting at f/3.5 to f/5.6... you probably will never miss having your target in focus... due to afma... not user error...

I find f2.8 on my 100L pretty thin already, and with my 6d vf I definitely cannot mf that tiny difference. So if there's a little spot to af on (like an animal's eye) the shot is lost even if the camera decides to lock on the eyelashes. This is not a "real" af miss or bad afma, but it has an effect of the keeper rate.

However, I guess the largest difference concerning keeper rate is print/view size. With the 100L wide open, if you really pixel peep on closer distances (not "macro", mind you) the af pane is often not 100% where you'd like it to be - so you have to define a personal threshold what's still ok and what isn't.

EOS Bodies - For Stills / Re: I just want a stills camera.
« on: February 23, 2015, 05:11:35 PM »
Does anyone else wonder this or long for this?

Lotsa people have been wondering for ages, and this is a very popular topic. The usual answer is that is afaik ...

  • doing special-purpose cams for a minority would be more expensive, so you're actually spending *less* money for *more* features on mass-produced still-video hybrid dslrs
  • not using video isn't very hurtful if you discount the stronger aa filter that might be weaker for pure stills
  • video is a "free" add-on concerning the technology, nothing special about grabbing frames of the sensor and then putting 'em into a video stream instead of a jpeg. Sure, they have to put some r&d into it, but not adding the existing firmware to a camera wouldn't do you any good.

If you feel very strongly about this, do a Magic Lantern "anti-feature" request - I guess it's fairly easy to disable (and probably hide) all video functions on your dslr to stop any confusion and malicious feelings :-)

Last not least, you'll *love* video on the upcoming 4k cameras if you can grab 120 raw frames from the video stream - compare this to an expensive 1dx that needs lots of sturdy tech to flip the mirror 12x per second...
