Am attaching unprocessed and my version. Pls advice. Any pointer is welcome.

How about sharing the raw, so people can have a go for themselves? Your first attempt looks too much saturated to me, and the sky gradient is already posterized. Second one is improved.

Btw this is exactly the type of shot that could do with a bit more dynamic range, the shadow resolution seems to be very low already.

auto mask is a bit flakey and can do some wierd things. I find its better to use the brush without automask to apply the setting and then erase using auto mask over the overlapped areas. this gives cleaner results

+1, I have yet to find a shot that works with LR5 automask - probably non-nature shots are compatible. But rejoice, as indicated in the newest ACR for PS CC the new LR6 will also have enhanced masking tools!

and if i was hiding the bird would be closer to me

"Birding" is indeed a bit like being lucky at hide and seek, and that's one problem: You can take an "ok" shot with your mighty expensive gear, and then the next guy with a Rebel kit lens happens to walk up right next to the bird, taking a better shot...

but if i didn't have 1/2000 he would be blurry.

... and that's the other problem: Even if you have a tracking camera (I wouldn't even bother with my 6d), "sitting duck" in lower light has an *entirely* different iso requirement than "in flight". With IS on and snapping a few frames, you can high iq shots w/o movement. When something starts moving at higher speed, you indeed need 1/1500 (horses) or at least 1/2000 (bif), and the iso value goes through the roof.

Here is one taken with the 5D III w/ 70-200 2.8 IS II + 2xTC II, import and export with no changes

Ugh. That's about why I stopped "birding" with my inadequate gear, in lower light and/or when the animal is far away as the results have a distinctive "90s mobile phone" look to them :-\ ... it's important never to tell that this was made using €5000+ gear :-p

For example, for many years, Intel would burn out defective cores and/or cache on their CPUs and change the product IDs so that they could sell CPUs that were partially defective.  One core of that four-core CPU doesn't work?  Burn out two cores and sell it as a two-core CPU.  Cache on a Pentium chip doesn't work?  Burn out the cache and sell it as a Celeron.  And so on.

Afaik Intel & AMD also deactivate perfectly working cores/caches if the demand for cheaper cpus is higher than their production :-) ... that's why there are always rumors of "soft-unlocking" schemes with number key you can purchase from the manufacturer. Maybe a business model for Canon - unlock your 18mp camera to 24mp or 11ev to 13ev dynamic range?

Canon General / Re: UK Cashback from WEX
« on: November 27, 2014, 04:17:45 PM »
Hope this saves you some money!

Meh - as far as I understand the fine print this is really UK only? I'm asking because I already ordered from WEX once because they have some gear that isn't available in Germany, and their prices are good.

EOS Bodies - For Stills / Re: 7DMKII Focus keeper rate ideas?
« on: November 27, 2014, 04:11:45 PM »
Actually, Rudy Winston is incorrect.  It's not 1/8th the depth of field, but 1/8th the depth of focus.  The latter is the sensor-side equivalent of DoF, measured in microns.  DoF changes with subject distance, depth of focus is relatively unaffected by subject distance.

Thanks for pointing this out, I was wondering about this very thing when I read the article.

Personally, I find the text to be a bit too much on the marketing talk side for my taste - and it's funny that the 2011 text points out that afma is totally fantastic and then they removed it from the 60d right after :->

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...

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!

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!
« on: November 26, 2014, 03:39:34 PM »
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.
