Site Information / Re: NEW ___ Sell Your Gear - Beta Test
« on: August 19, 2014, 12:34:44 PM »
Well, I'd like to sell my Sigma 35 ART and my two California Sunbounce reflectors, but I obviously do not qualify for your beta test.
Maybe others feel the same way I do?

I'd welcome such a sub forum as well! +1

Where did you get that information from?

It does not make much sense in my opinion, but who am I to judge?

Lighting / Re: Elinchrom - turn off single flash
« on: June 27, 2014, 09:11:20 AM »
I understood from their reply that I cannot turn the flashes off / on independently. I had another idea which might work - I can turn off specific groups using the ST-E3-RT. I could connect a Canon flash to an Elinchrom flash using a cord. If I then turn off the Canon flash, the ELC would also not be triggered.

That is a rather expensive solution as I would need a 600 Ex Rt for each other flash I want to trigger.
Are you aware of any Canon RT compatible 3rd party triggers?
I know Yongnuo has created a flash, but I haven't heard of a simple trigger...

Thanks for your suggestions!
I asked the Elinchrom support about this - this is what I got as a reply:

In the Skyport system you can have separate groups (1 to 4) and use them individually or ALL. If you would like to trigger your speedlites and the ELC together, the easiest is probably to use the pre-flash intelligent system built in the ELC Pro HD units and let the ST-E3-RT do the syncing. You can still use the Skyport to adjust the Elinchrom flashes.Hope this helps.

Hello everyone,

Is it possible to turn off one (or more) flash groups with the Elinchrom Skyport system while all other groups still fire?

Long version:
I do have multiple Canon 600 EX-RTs and the ST-E3-RT. Sometimes they just do not give me enough power when I want to light up a whole room (i shoot events every now and then).
My plan is to buy some Elinchrom flashes, place multiple lights in the room and to assign different groups to the flashes.
When I walk around during the event I'd like to turn off / on the flashes just as needed.

Is the Skyport system capable of doing this?

I'd also like to know if I can connect a Skyport universal trigger to the ST-E3-RT? I imagine carrying around the ST and adjusting the Speedlites  while adjusting the Elinchrom flashes with the Skyport.

Thanks everyone for your feedback!

Dear surapon,

You are an important member of this forum and I really like reading your posts so here is an answer:

1) Changing the name of your picture file has no effect on image quality.
2) If you change the file size (making the picture smaller or reducing JPEG quality) your picture will have less quality. But to be honest, FB, Canonrumors and other forums do net need that high quality (unless you want them to zoom into 100%). So from my point of view yes, quality will be degraded but that is OK for internet use.

If you are interested in reading details I suggest you read this very good article:

EOS-M / Re: Got my new IR eos-m!
« on: June 12, 2014, 08:01:04 AM »
Congrats, looks great!
I have been playing with my X100s (weak IR filter compared to other cameras) and IR photography in the past and got nice results - however I expect your modified M to deliver far better results.
Please share some pictures :-)
I especially enjoyed taking pictures of people with sunglasses - they disappear completely. :-D

EOS Bodies - For Stills / Re: 5D3 Auto ISO
« on: June 09, 2014, 06:11:37 AM »
I'd really like to try the auto_iso module, but I was unable to find a binary for the latest 5DIII firmware. The ML forum thread has some binaries, but only for the old 5D firmware.
Marsu, where can we download it? I won't complain and understand that the devs and you are not responsible for any damage this might cause :-)

EOS Bodies - For Video / Re: Quick start videoing on 5Diii

Be careful about the picture style you choose for the video. Yes, the picture style for jpegs affects video, too.
In most cases you would want to choose a rather neutral, flat style and add the punch in post production. Otherwise you might get a bad histogram.

EOS Bodies - For Stills / Re: Focus indication with manual lenses
« on: April 22, 2014, 10:14:39 AM »
The focal length divided by the aperture (ie f/ number) isn't just total light availability:  it also defines the angle of the incoming cone of light that focusses onto the film/chip.

This has caused a lot of confusion, with people wondering why we can't use an f/8 lens in bright sunlight even though focussing at f/5.6 works in near-dark conditions.

Phase detect AF (the good and fast one that we all love) samples from two points in the incoming light cone, and the phase difference between them shows the amount and direction of focus needed.  (Obviously this is per focus point, we're just looking at the centre point).  Out of focus images show an image shift depending on which part of the incoming light cone is being looked at.

The further apart you sample in this light cone, the better the parallax and the easier it is to focus.

- Most cameras sample the cone at the equivalent of f/5.6 (39.3 degree light cone)

- Some also do f/2.8 (wider cone, so accurate and fast when available).

- f/8 (28.1 degree light cone) is rare and expensive because the cone is narrow and the difference between images at each focus sensor is relatively small.

Different sensors are chosen depending on the lens attached and its current zoom (which usually affects the f/ number).  This is why your camera cares about getting aperture info.

There is no reason it couldn't TRY to use its narrowest AF and report to you what it thinks is going on.
There is however a business reason:  Why would Canon want to make it easier/nicer for you to use non-EF lenses?

Excellent explanation, thank you - always good to learn something new.

Canon General / Re: Off Brand: Nikon Announces the D4S
« on: February 25, 2014, 09:20:42 AM »
I'm not really impressed by this announcement.
The 1DX is still far superior.
As other have said, I would have liked to see some pressure on Canon but this announcement is nothing to worry about for them.

I took this picture on a recent trip to India. I did not bring my 5D3, went only with the X100s.
This was such a peaceful scenery, I'm glad I had a camera with me.

I took these with my X100S as I did not want to travel with my 5D3
I know the 'foggy' effect of a long-exposure is sooo overdone and soooo out, but I never tried it myself - so I just had to give it a try :-)
Feedback appreciated.
