Viggo said:Stu said:I have 4 600EX RTs and the ST-E3. The Canon ETTL-II TTL system seems to throw these off. When I have my camera in manual mode and the flash units on ratio the exposure values vary greatly as I move around on the set. I have not been able to figure this out. Over exposure up close and under exposure at a distance. That is what I had with my ST-E2 and my 580EX IIs. In order to overcome this I just change lenses to get the "sweet spot" for the flash. It is irritating enough to me to consider dumping them and moving to Profoto's new B1 strobes. Ideas?
Use them in Manual, ettl I still find completely useless..

Yup, steal the private key! Unless you use crappy settings and short length key to create the key, or keep the private key somewhere easy to access, unencrypted/no password/crappy password.
Or at least, that's what law enforcement will do. Oh, wait, they'll just make a bogus claim and force you to turn over the private key </sarcasm & tinfoil hat>

<p>NEW: Personality of the Canon Cinema EOS Lens: Design Strategies
The newer generation of Cinema EOS lenses came from multiple optical design resources within Canon, such as ourEF Lens and Broadcast Lens designs.</p>
<p>NEW: Personality of the Canon Cinema EOS Lens: Image Sharpness
A design goal with the Cinema zoom lenses was to achieve an overall optical performance that would equate with the best of contemporary prime lenses over their respective focal lengths.</p>
<p>NEW: Personality of the Canon Cinema EOS Lens: Color Reproduction
The new generation of Canon Cinema lenses paid high attention to optimizing color reproduction of the lens-camera system, such as how it reproduces skin tones of various ethnicities.</p>
<p>NEW: Personality of the Canon Cinema EOS Lens: Contrast
Achieving a high contrast ratio is universally sought by cinematographers and is always a central design goal for the optical designers.</p>

gshocked said:Hi,
I recently purchased the Lumiquest Event kit and have been using the Quick Bounce a lot.
Its great if you are shooting out doors and on a sunny day and want a bit of fill light to light up the subjects face. Also works well when you don't have a roof low enough to bounce off. Hence, why I went with this and not a Gary Fong Lightsphere..
The quick bounce also allows you to open up these little barn doors, which claims to let 80% of light out and then you get 20% of light reflected at you subject. I also have tried closing just one of the doors, which is suppose to bounce 40% of light.
I found this nice review on it, which I'll post up when I find it again.
This is one of the few English videos on youtube about this product. Its biased as he owns the company, I think, but at least it gives you an idea on how it works:

jrista said:Only thing I can think is that the registration distance of mirrorless cameras is so small that maybe flare is exacerbated by slight reflection off the sensor. The registration distance of DSLR's is much larger, so any kind of reflection off the sensor will fall of to almost nothing by the time it reaches the lens again. With EOS-M, or pretty much any other mirrorless camera, the registration distance is only a couple/few millimeters.
Yeah I wondered about her sudden disappearance ... she was a cute little thing that added that extra zing to the videos.AcutancePhotography said:Rienzphotoz said:In comparison to many of his more entertaining videos, yes I agree.AcutancePhotography said:gshocked said:I like most of their videos but I do wish they put a bit more thought into substance vs humor.
I am a big fan of DigRevTv. But I have to say that this particular video lacks either.
No where factual to be useful
Not really all that funny to be entertaining.
I think Kai kinda phoned this one in.
Besides without Alamby, it just ain't that good.
I hope she is still with them. She has not been in the past few videos. She really added a lot to the videos.

Mt Spokane Photography said:Quasimodo said:I might have given up to easily... Which brand do you use?
I use Sensor Swabs (Brand) and moisten them with eclipse fluid. I've had a lot of junk get on my sensors from the pec pads I bought, and from the pre-moistened Sensor Swabs.
Good sensor swabs are not cheap, and when it takes 5 of them plus the expensive eclipse fluid, I cringe. $32 for a dozen ff sized dry ones plus you need the eclipse fluid.
Most of the time, a rocket blower does the job, but I've had some gunk that was difficult to remove on my 5D MK II and my 1D MK III.
Amazon has them.

Better but more expensive. The current Hasselblad 50mp is $26,000!! And that's without a lens!
