EOS Bodies / Re: 7DII No Wifi
« on: September 15, 2014, 04:08:35 PM »
Another +1.

The facebook comment made me laugh, as it's the first remark I hear when someone finds out that my camera has WiFi.  And I don't even know if the GPS on my 6D works; never felt compelled to find out.

Lighting / Re: Yonguo YN560-TX Transmitter Released
« on: September 15, 2014, 12:11:28 PM »
I got to give mine a try this weekend, but just for a quick portrait session – my real intent with it is for architectural work where I often have flashes in other rooms or even outside.  For portrait/product work it’s probably faster to just adjust power at the flash.

That said, for $50 I’m pretty impressed.  My only real complaint is that the up/down buttons only do the 1/3 stop increments, I wish I could use them to quickly choose groups and have another button combo for fine tuning.  Lack of AF doesn’t really bother me, as I use manual focus for my architectural work and my 6D usually finds focus regardless of the lighting.  But everyone has their own uses and work flow.  Seems like it wouldn’t have been hard to put AF in, but what do I know.

I’m sure I’ll end up buying another 560 III or two just for convenience, although I have no need for more flashes.  It would have been nice to have them function in groups with the 602/603, but I’m sure the technology just wasn’t there (unless you used channels).  For my work I can’t really see using more than 3 groups, and it’s not usually the absolute power of the lights as it is the ratio relative to the others.  So 2 or 3 controllable lights should be sufficient, and the others can just be dummies.

Lighting / Yonguo YN560-TX Transmitter Released
« on: September 10, 2014, 12:10:09 PM »
I didn't see any other threads discussing the transmitter, other than one on the 560 III.  Looks like Yongnuo released the new transmitter back in June.  Looks promising, remote power and zoom control of the 560 III, plus dummy triggers for 602 and 603/II receivers.

There's a couple of reviews online. Anybody get one of these yet?

Lighting / Re: How to Extend Flash Performance (Life on Site)
« on: September 08, 2014, 12:30:19 PM »
As RLP noted, you can use a wider aperture and up your ISO a bit.  You can also use two flashes (if off camera) at half the power.  Just knocking two stops off your flash can have a significant impact.  My flashes can fire all night long at 1/16.

Post Processing / Re: Too much chroma?
« on: September 04, 2014, 12:03:22 PM »
I agree with both of them, and I'd combine their advice.  I'd warm the foreground, then I'd take the saturation of the whole thing down a notch or two.  I'd probably dim the foreground a tad too, as it just looks to light given the sunset.

Software & Accessories / Re: Anyone interested in a triggertrap?
« on: September 04, 2014, 12:00:24 PM »
So I just thought I'd ask if anyone was interested in the new Triggertrap. Reason I ask is I have the chance to get an additional for 35 pounds and I see on their site that it's currently listed at 179 pounds.

According to the kickstarter page posted above, the 35 pounds backer only gets a timelapse kit.  No laser, no sound, no light, no PIR, and no extras.  Just FYI.

Post Processing / Re: Posterization - 5D III HDR
« on: September 03, 2014, 04:01:45 PM »
A sunrise or sunset does have an enormous range of tones, and automatic processing is going to be severely challenged to produce a good result. I forget whether in HDR mode on the Mk III you can set the number of images to take. For a shot like the one you describe, I would think that 5 or 7 images might be necessary to prevent posterization.

Why would more images help reduce posterization?

Post Processing / Re: Posterization - 5D III HDR
« on: September 03, 2014, 11:11:50 AM »
Color space isn't going to have an impact on posterization.  Technically you're going to get it anytime you decrease the bit depth of an image.  But you can minimize the visual impact of the final image.

I've never used in camera HDR for this reason, you lose control of the process. HDR & tone mapping are far too complicated of a process to leave up to the camera, IMHO.  If the result really is unusable then I'd recommend giving a program like Photomatix or Enfuse another go.  I'm certain that there's nothing that your camera can do that either of these programs cannot.  It just takes some practice to get the results you want.

Lighting / Re: Yongnuo vs. Pixel?
« on: August 27, 2014, 12:23:12 PM »
received a Classy NO from Yongnuo today.

"Hi dear user,
 
Thanks for contacting us!
At present, all the YONGNUO products are mainly designed and developed for Canon and Nikon. For we don't have a Pixel Mago flash to be tested with our products, we are not sure if it's compatible with our products. If possible, we kindly suggest you to take your device to a physical store to test with our products to avoid purchasing a wrong device.
 
Thank you very much for your attention to YONGNUO products! If you have any other questions, please feel free to contact us again.
 
Best regards,
 
YONGNUO"



as yongnuo is already well established on third part flash market, they won't give in as expected.




the answer from pixel looks like a kung fu deflection:

"Yes, we did found this issue. But our Mago can work with original flash. If not, we will develop new firmware to correct it.

Since there are so many flashes on the market, so cannot make sure every flash can work with the Mago.

 
Anyway, thanks for your support.

Good day!"


no comments about this last one. I'm hoping magic lantern or something crack this then  :(

I'm actually surprised that the Yongnuo response was so well written, especially considering what their website and instructions look like.  Obviously the response from Pixel is the results of your original email being filtered through an online translator, and then their response back through the other way.

To their point, you can't expect third party developers to consider products from every other third party vender.  It goes against the basic concept of cheap third party alternatives.  And you're right, they don't want you buying other third party gear, they're there to persuade you to buy theirs instead of the name brand stuff.

Post Processing / Re: Photoshop eye retouching
« on: August 19, 2014, 12:59:59 PM »
There's a couple of Phlearn episodes that discuss a different techniques.  One in particular, which uses a bit of color to enhance what is already there, then essentially a dodge/burn that is scribbled on the iris and then gausian blurred to blend in.  The effects can be very striking, and always, if it's too much for your liking then you can dial it back.  Search on YouTube or Phlearn.com.

Can't argue with that.  Sage wisdom, up there along with "buy low, sell high".

Lighting / Re: HSS power loss
« on: August 19, 2014, 11:51:55 AM »
Why not take a photo at max sync speed, then just go up 1/3 a stop and see the difference between single pop and HSS.  It would minimize the impact of shutter speed, which will directly affect exposure in HSS.  Once you establish that difference you know that you'll lose a stop every time you go up a stop in shutter speed.

That is exactly what I dd in my first reply. Going up 1/3 stop above sync cost 2 and 1/3 stops of power.

Sorry, you're right.  I saw a bunch of discussion involving changing the aperture and shutter speed and whatnot and it seemed to be over-complicating things.

... is at the highest levels of photographic excellence?

Do you work at my company?  Because they love to use sayings like that.

Either one is fine performance wise, I really don't think you see much of a difference.  As Mack G pointed out, you can feel the difference a lot more on the bigger tripods.  Funny thing is, that it doesn't matter to me on the bigger guys, because I'm not strapping them to a backpack and hiking with them.  I have a big aluminum, and a small CF.

EOS Bodies - For Stills / Re: Fun Arias rant on APS-C vs. FF
« on: August 14, 2014, 10:50:26 AM »
High ISO performance is significantly better with FF.
Nope, not even close to true.

It's precisely this sort of unconditional sweeping statement - which has been demonstrated more times than tongue can tell to be nonsense - that sticks in some folks' craw.

Fact: my 7D and especially my 70D, are night-and-day better at low light/high ISO than, say, the old 5D - so right there is a perfect example of the lie that the statement "High ISO performance is significantly better with FF" is.

Other things being equal a FF sensor should beat a crop sensor of the same technological maturity, but that's an utterly different statement to the "FF is always better" meme that gets interminably churned out.

Let's see a 5D do better than this: 10,000 ISO with my 70D. Straight out of Capture One 7 Pro, default NR and no PP NR.

And check the Exif in the image - there's hardly any light on that scene...

Here's a 100% crop from the same camera -"only" 6400 ISO this time, but again, straight out of Capture One, at default NR.

Each easily beating what the older FF cameras (including the older 1Ds pro bodies) can do.

Of particular significance is that neither the 7D nor (especially) the 70D throw out the high ISO banding/pattern noise that bedevilled the 5D/5D Mk II - so right there, you've got a significant high ISO performance improvement.

I'm amazed you decided to take that much time typing an extensive "response" comparing 10 year old FF technology to a modern APS-C.
