I just showed this thread to a psychologist who's used to working with obstinate and "damaged" children; she almost wet herself and asked to borrow the bathroom. I don't know if it was from laughter, or if she got a glimpse of future revenues...

Photography Technique / Re: DIY: Monitor Hood
« on: Today at 09:49:29 AM »
I decided to make one for myself. I spent around $26 at Office Depot for a set of three, 30"X40", foam poster. With little tape, tape measure, pen and a box cutter, I came up with this.... ;D

Looks exactly like the real thing I'm using in the pro print shop before sending off my images. And of course the ambient light has to be dimmed down so your calibrated monitor can remain at a low light level.  Working like this certainly proves that calibrated editing is not meant to be fun :-\

So here it is, hobbyist advice to a newbie hobbyist:

Intersting to see what people find is important - 3 years back I'd also have mentioned raw and the like, but now I find the picture content much more important, no matter what. You can probably pixel-peep only for so long before giving up :-p

see what is in the background

Or learn to use the content-aware healing brush :-) ... often cannot be helped with wildlife as you cannot
direct the animals around to stand in front of the most favorable background.

No Polaroid  The prints are faded, and for all practical purposes gone.

The venyl record crowd would that as an advantage - you can only evaluate something if you cannot use it indefinitely and/or the time is limited. You probably remember those polaroids from decades ago better than you'll remember your current digital data heap in the future :-)

It's a really great photo that tells a story of its period. The gross American car just peeking through on the left

My thought exactly! The car being cut off, the composition makes it all the more interesting. There's certainly something to be learned here!

Photography Technique / Share 3x your own advice to yourself!
« on: November 26, 2014, 06:36:23 PM »
Here's good ol' Marsu's latest scheme to help each other out by sharing some knowledge :-)

If you could time-travel 3 short pieces of advice back to yourself when you started of with photography, what would it be?

I'll go ahead!
  • shoot loose
  • calibrate your monitor
  • tell a story

Now, don't be shy! What did you miss back then you've learned by now?

It seems it's primarily intended for cinema...but still...14 stops at ISO 100, 21 stops at ISO 5120, and the thing doesn't drop below 10 stops until an insane ISO

Can someone please explain simple /me how it has more dr at higher iso?

Frickin nuts man...when the hell is Canon going to get into the sensor game?!!?!?!?!?! AAARRRRG!!

Fortunately, it has been established by popular opinion that you don't need to go beyond what Canon offers and don't feel limited, if you know your equipment, that is :->

Ok, but sarcasm aside - from shooting with ML's dual_iso I have a vague idea how much dynamic range daylight high-contrast shots have. I'd say with 15-16 stops you should be really covered for most natural scenes, 14 is fine for most purposes unless the sun is in the frame. So what's 21ev for?

Lenses / Re: Landscape Lens for Crop To Make Me Go Wow!

Using Photozone as a reference it looks to me as if the 70-300L cannot quite fully resolve 15 mp on APS-c when wide open at 70 mm, let alone 18, but the OP never said he was using this lens wide open.

Good point, but then again I didn't say so. To repeat myself - and we could probably just ask the op :-p ... he's bound to have used the 70-300L wide open at some point. And if he'd had found it lacking, he probably wouldn't have used it as his reference what a good lens is to him (see below).

I disagree with your last sentence because the 'very best' in resolution terms doesn't have to be 'the most expensive'. These high mp asp-c cameras need really good lenses, and Canon now provide ones that are up to the job without being expensive; look at the 40/2.8 and the new EF-s 24/2.8.

Come on, this is self-explanatory, isn't it? Of course I was talking zoom against zoom, prime against prime, we all know you can get excellent iq if you use an older manual prime or any newer generation.

In terms of the 70-300L being wow, compared to the 18-135 on my body, it's wow :-) There are certainly times when the image isn't quite as sharp as I would expect but I put that down more to user error and a bit of post processing can usually help. All you are doing by showing comparisons on how sharp it is on FF is making me envious! I usually shoot it at 5.6 so then I can treat it as a constant aperture lens across the zoom range.

This is just what I do with the 70-300L on crop, and it's fine this way and has a very nice bokeh.You really only realize the difference with fine details, apart from the thinner dof on ff.

I mostly shoot horses and focus on their eyes - and here there's a visible difference crop vs ff. And of course to even better lenses like the 100L (which is an example of a lens that is just as good on crop).

Of course, as you wrote, if you downsize and the details happen to respond to the usual sharpening algorithms, no one see a difference. Btw that's why I didn't stretch my budget to get the larger 70-200L.

Technical Support / Re: 7D mark II battery drain
« on: November 26, 2014, 02:11:29 PM »
True but if you are not going to use those functions then why use ML?

Basic usability: key remapping, rating with a key (for cameras that don't have a dedicated button), pic review brighten/darken, ... little things, but the very annoyances Canon uses to upsell people to more expensive models.

I wonder why Alex doesnt take someone under his wing to continue development when he's unable to.  Anyway that's a discussion for another thread.

I'm seeing ML sailing into troubled waters as alex is the bottleneck and all attempts to expand the dev base have failed so far. But it's indeed off topic, and probably not worth discussing anyway as nothing can be done about it. Point to remember here: Don't expect a stable and working ML on anything but the 5d3.

Hmmm but there is no ML for the 7DII and likely wont be for quite some time.

Sorry, I forgot this is a 7d2 thread - but maybe there are some people with other cameras around here, too. Atm I don't see ML going anywhere beyond the 5d3, not even to the 70d.

Further, use of ML has historically used more battery power due to more CPU usage to drive all of the enhanced functionality.  So to say that gps save is a powersaving function is a bit of a "marketing" twist.

ML doesn't drain significantly more power when it's doing nothing, i.e. you have no features enabled or very basic ones like the gps powersaver which only runs a short function on camera on/off. And you're free to disable it at any time on camera boot. The things that draw power are focus peaking and generally all live view visual operations.

The digital picture ISO crop comparisons between asp and ff are one sure way of putting someone off buying a crop camera.

Ugh? Why would I want to do a thing like that? I'm an outspoken fan of crop cameras for macro and general low iso shooting and like my snappy 60d over my 6d. But there are some lenses that gain by being put on crop (cutting off blurry corners), and some loose (lack of sharpness wide open), and some have both effects at the same time.

Here's a link to 60D with Zeiss Otus and 1D with Canon 50 f1.4

Fair enough, so let me re-phrase it: The tdp comparison of the 70-300L happens to show - for whatever reason - about what I see from my copy of the lens on my 60d and my 6d. Which brings us to the all-popular "wrong afma, broken lens, bad handling" theme, but I don't think so in this case.

This was about a different point anyway: If the op is fine with the 70-300L on his crop, I don't think there is a need to look at the very best and most expensive lenses for him.

EOS Bodies - For Stills / Re: Is there any reason to shoot sRGB????
« on: November 26, 2014, 10:45:30 AM »
Oh really? I'm interested in stuff like that. Name some german printing sites which are using wide gamut colorspaces.

I'm using this one: http://www.saal-digital.de/service/support/artikel/Article/show/sartikel/icc-profil-im-photoshop-einrichten/ ... by delivering pictures in srgb you might loose some gammut their devices provide. Ymmv a lot if you actually see the difference between a shot delivered in srgb vs argb though, but you can check by using softproofing with the respective icc profile.

Adobe's linear gamma and proprietary version of ProPhoto, named after the developers wife Melissa Gaul, is still for all intents and purposes ProPhoto. I was trying to provide a simple explanaton for a user who may be intimidated by color management.

Thanks for not burdening us with accurate explanations, but keeping it simple :->

I admit, the GPS function will continuously drain (of course, it's working) but the idea that it should shut itself off means it will spend time and energy  resetting itself each time you turn it on -- so, the lesser of two evils here.

Magic Lantern has a gps powersave option that turns gps off on camera off and remembers the state when turning it back on.

Back to the point -- at present, I shoot with all Canon gear -- and can't fathom missing a shot in the field because the lens forgot to adjust in some minor way.   It's not like "horseshoes" where close counts - either the gear works as its designed, or it doesn't - and the opportunity for the "doesn't" (even minimally) increases when you interbreed brands. JMHO ...

I've also avoided 3rd party lenses so far, and have a bad experience with the Yongno rt trigger. Having said that, sometimes there isn't really much of a choice. For example. only Tamron has a 24-70/2.8 zoom with IS and its half the price of the Canon mk2. If given the choice between a Tamron lens or no lens at all, I'll take the Tamron :-)

Curious - my Youngnuo transmitter (622c) dont do that.

Yn did a botch job with their rt transmitter, imho it wasn't ready for release neither in hardware nor in software.

I don't notice a battery drain on my old 7D, but I haven't my own Tamron optics.

It only happens with newer Cameras, Canon keeps changing/updating (and is free to) their proprietary lens communication. That's the big drawback of buying 3rd party flash/lens gear, and the reason why Sigma and Yn now have usb interfaces for fw updates.

Hi I used the EF-S 10-22 with my first digital camera, the 20D. It was a fantastic lens so I wonder why canon didn't put a red ring on it.

1. marketing
2. lack of weather sealing (which (afaik) all recent L lenses have)
3. probably general build quality, compare with the recent 16-35L.

That might be true in your case, but it doesn't mean it is universally true. Nailing every one of those 18 mp on your 60D with a 70-300 takes some doing. With really sound technique the only difference will be the amount of post shot magnification required.

I shot about 100k frames with my 70-300L on my 60d, so I guess some of them were in focus and without shake or motion blur, even if only by pure chance. And at least with my copy there's a distinct difference between f4 on crop vs. ff - that's why I mostly stepped down to f5.6 on the 60d. Here's exactly what I see:

Post Processing / Re: Assembling Portraits
« on: November 26, 2014, 07:29:23 AM »
Thanks for replying. It's always good to get an opinion of someone who has more knowledge.

Did I say that :-p ? Problem is that online, this is hard to verify if someone's talking off the top of his/her head.

In my case, I mostly do wildlife or pets+people, but I researched some into weddings and associated shooing situations - that's where I learned about the group portrait face exchange. But don't rely on that working, actually you want to have an assistant around watching out for drop shadows, occluded faces, bad hair, ... in case you're to busy with your gear to notice everything.
