I think the relevant part of the review is that the Mitros was compared to the 580EX II, and IMO you'd need a very very good reason not to get into either 600EX-RTs or their Yongnuo clones.

1D X Sample Images / Re: Any Thing shot with a 1Dx
« on: April 07, 2014, 08:23:57 AM »
Thanks guys, much appreciated.

One question though. All three pictures went through exactly the same process and adjustments (hardly any). But on my monitors, of which one is a self calibrating Eizo, the third image has totally different colors than the others. Does any of you have an explanation for that?


Hi Eldar, do you know if you changed color profiles in there?  The ones with the weird colors look like what you get when you try to display an image with an ICC V4 profile on a monitor which doesn't support it.

http://www.color.org/version4html.xalter might be relevant.  I had a devil of a time figuring it out until I realized I had my i1 display pro calibrator set to create an ICC v4 profile; that has some performance benefit but apparently isn't widely supported.

ETA - I opened the original image (_D7T4966-2.jpg] in PS CS6 and the colors came out substantially like the second image _D7T4966-3.jpg.  In Firefox and Irfanviewer the original had that weird cast to it.

They're shot in the same burst(s), within 20-30s from first to last. Camera set to manual mode, with auto ISO. WB temp=5700 on all images, but tint was increased from 14 to 15. No profile change.


I don't mean that it was a camera setting but rather something in your workflow; either an ICC v4 profile from one of your calibrators or a ProPhoto color profile.  Come to think of it the latter makes more sense considering that the off-color image opened ok in CS6 but not in Firefox which is ICC v4 compliant.

Software & Accessories / External AF assist light?
« on: April 06, 2014, 10:38:10 PM »
There I was shooting bullriding in a cave-dark arena yesterday, and occasionally I had trouble getting AF lock on a 1Dx with a 70-200 f/2.8L II.  Lo and behold Thinkgeek has flashlight-size IR lights for sale, would one of those be any use out to about 100 feet?  I might shop around for something which runs on AAs and has provision for a remote switch, but only if the idea is sound.

You know to look at the eyes on Harbour seal 2,  I'm glad it is in the water and I'm not!

Bullriding yesterday.  1/800 is better than the 1/250 I had the last time out, I look forward to seeing what I can do with better flash placement to get the ISO down and the shutter speed up.

Lenses / Re: Canon 50mm f1.8 MK1

I expect - in light of Sigma and Zeiss' new 50 f/1.4s - to see a new 1.4 before they do anything with the Plastic Fantastic.

If so, skip the mid range and aim straight for L glass. Glass before body is the name of the game.

Newbie Question: How can we tell if the lens we're interested in buying has "L Glass?" Is there an "L" in the product name or something?

A red or (much less commonly) green ring around the end of the lens, or an L following the advertised aperture.  There are similar lenses which have L (Luxury) and non-L focal ranges, the 100mm f/2.8 macros and some of the 70-300 or so zooms.  If you can get L lenses in good shape second-hand they usually hold their value well enough after that, that owning them is basically a long-term rental.

Huh.  I thought it was the other kind of bayonet mount.  Imagine that, some hipster spearing the brim of his fedora in the process of answering a call...

What about exporting from Lightroom and cropping to multiple files in another app?  I don't know which one but it might be easier; watermarks might be a hassle though.

I would buy a 77mm circular polarizer and step rings to fit the lens you have now and the nice wide lens you could rent for your trip.  Also take a decent tripod and enough cards that you can shoot either raw alone if you're comfortable with that or raw+jpeg.

As much as Kai is a little abrasive at times I have learned from their videos, and the three of them (he, Lok and Alamby) add up to better chemistry than a lot of contemporary TV.  I wonder how they are off-camera, I'm pretty sure Kai is hamming it up a lot.

Photography Technique / Re: 1D X - 12 FPS or 14 FPS?
« on: April 02, 2014, 05:27:05 PM »
I've never used 14 FPS, I regard the trade-offs as not worth it.  Lights recycling have been more of a limit than the mirror.

Canon General / Re: Travel charger for Canon LP-E4N battery
« on: April 01, 2014, 07:02:44 PM »
In a perfect world the batteries would be like the ones for a device at work: The wall-wart plugs into a charging base which can charge two batteries, or directly into one to charge it and power the device.  In the meantime, we have the current (sorry) debacle.

Then there was this and this.
