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?

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?

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,

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.

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. 

Pricewatch Deals / Re: Searching for a lightroom 5 deal...
« on: August 13, 2014, 03:34:43 PM »
I believe what happened is that a good long while ago I told the computer to check for bad sectors on the hard drive... but it could only doo that after a restart.  So I forgot about the check... a few hours las and I assume the hard drive is fried.... but after a few more hours, the check is finally done and it is as it was... but there are some bad sectors...

I was able to retrieve my light room code and I was able to put it on my laptop as a backup... but all in all I can see why film has a certain draw...

I'd replace the HDD before it finally goes kaput, and might as well upgrade to SSD.  Personally I'm done with HDD except for storage.  Solid state drives are really affordable now, just picked up a 500gb drive for just over $200.

I was content with using lightroom 5... and then my desktop computer decides to commit suicide... thought it might have been auto erotic asphyxiation considering the materials on the hard drive... but I digress. 

If yall come across any decent deals with LR6 as an add-on or on just the software alone... I'd be very interested. 

I'm sure this goes without saying for most people, but I'm not interested in the Creative Cloud.

Also, when you buy the software... you can get a multi-use registration code... because I would want one for my laptop and for my desktop's successor.

There is no Lightroom 6, yet.

Their website does not seem to offer the option of downloading a "standalone" version anymore

On the other hand......   https://www.adobe.com/products/catalog/software._sl_id-contentfilter_sl_catalog_sl_software_sl_mostpopular.html?promoid=KLXMI

Typo.  Actually my desktop revived itself.  Though it certainly does seem it is time to replace the machine.  It is two years... and while I'd love to get more time out of it... it seems an update is required.

I know this is a month old and off topic, but in case you're still considering upgrading: I would wipe your harddrive (after backup of course) and reinstall a fresh copy of Windows and all your programs.  I've been meaning to do it to my laptop for months now, and never got around to it.  My hard drive crashed last weekend and gave me no choice.  I did upgrade to a SSD, which I highly recommend, but other than that it's my 2.5 year old laptop that has been sluggish for awhile.  Now it's lightning fast again.  I used to do all the registry cleaner stuff and defrag, which helped, but only so much.  I think all those fragments of files long deleted just build up after awhile.

Anyway, give it a shot.  You've got nothing to lose, you'll have to transfer everything over if you get a new comp anyway.  It took me a full evening of uploading stuff, but I feel like I basically got a new computer.

Feel free to enjoy a Rebel XTi with the 18-55 non-IS wide open.  After all, you choose the colors.

What does non-IS wide open have to do with colors?

Lighting / Re: 600EX-RT - invalid dead battery indication & fix
« on: August 12, 2014, 01:15:18 PM »
Battery geometry can be a big issue.  That little nub on the positive end varies in length from AA type to type.  Some electronica will accept them all, but some have a barrier that stops the short nubs from making contact.  I had this issue with electronics I import, some batteries would not make contact.

However, that obviously is not Jims issue.

Battery geometry shouldn't be a big issue.  It's not exactly rocket science to design a battery holder that can firmly make contact with a battery given some tolerance.   I just don't see it as a complicated design requirement, and certainly not for a $600 piece of equipment.  As to applicability to Jim's issue, I agree, this shouldn't be the cause of it, but it is what's stated in the instructions for the 600ex.  And every time I've heard of similar complaints with the 600ex someone puts alkalines in and the problem goes away.  So either Canon poorly designed the battery contacts, or they put some fluff in the labeling instead of design a battery indicator that can handle various rechargeables.

There's been various reports of issues with the battery indicator when using NiMh rechargeables.  Something that Canon is aware of, but they simply put a statement in the instructions to only use alkaline, and added some B.S. about the battery geometry not being compatible.  I haven't really followed the issue closely since I don't have 600ex-RTs, but I'd guess the issue is sporadic at best since I'm sure there are thousands of 600s out there using rechargeables.  Glad you found a workaround.
