You are right i mixed up those.
Any way to trigger Silent picture full resoultion remotely? 5d mk2

I need to take picture of 8mm film frame and wait for next frame and then take another picture etc etc.
Motion detect works only for 1 picture/frame. :( Intervalometer desyncs over time with my 8mm film motor drive.

Remote trigger connector. ;-)

good morning guys ... i have a problem and i would like to ask for help: i'm trying to use the silent picture on my T3i and when i press the shutter button halfway down it takes the picture but saves it with a very low resolution, even though set full_res..what can it be? thanks

Basic steps:
Restore ML defaults. Retry.
If problem persists check crop setting in Canon menu (Digital Zoom OFF). Report back!

Thanks. After some test looks like it will work.  8)
Weirdly focus pin takes only silent pictures and trigger pin takes 1st silent picture and then normal pictures with shutter.
UPDATE
With remote trigger silent pictures takes only odd frames and skips even frames. It looks like one trigger means get ready and other trigger means take a picture.
With motion detect i could capture every frame. Is there any way to lower lag, make camera ready for next frame sooner?

Thanks friend ... I was just opening the image with the wrong software ... now the problem is different: all images I take of the sky are blown up, what can I do to improve this? thank you again

I don't know if I could post links from google drive, but that was the best way I found to post the image ... today the sky is rainy, so the image was not so clear, but yesterday with sun and the same configuration left the image very burst

There are 8 different 18-55 lenses (if I counted correctly). Please specify and tell us if there are other lenses in your repository showing or not showing this error.

According to exiftool you're using 8-bit, right? Change to 12-bit instead...

when I get home, I'll check ... I don't remember the exact model now ... I just know it's the same lens that comes with the camera when you buy a new one

According to exiftool you're using 8-bit, right? Change to 12-bit instead...

how do i do it exactly?

It opens on rawtherapee too, but the dynamic range is very limited. The white point seems wrong too.

The file is fine. Did you try other nle than rawtherapee? Export to tiff with dcraw then check the file. Same result?

Looks fine in ACR. I can pull out details in the highlights and shadows.

ACR reconstructs highlights by default, IIRC. On Rawtherapee (without HR), the clipped skies are pink:


But it's not like it is an unusable image though:

Hi, since the usable shutter speed range is extremely narrow on my 550D (0.5 to 0.8 sec) for the FRSP, I am thinking about swapping the 550 body for something that plays better with FRSP.

I have read quite a portion of this thread as well as searched for info on specific cameras in it. I am still not 100% sure what are the usable shutter speed ranges for various cameras. If you own one of the following cameras and have experimented with FRSP, could you please tell me what is the usable shutter speed range?
And if possible please state what lens you used and whether the aperture worked or not (preferably verified by looking directly into the lens and watching the diaphragm blades close or remain wide open when the FRS picture is being taken at say f/16 aperture).

for example (my camera):

EOS 550D
usable FRSP shutter speed range: 0.5 - 0.8 sec
lens tested: EF-S 18-55mm 1:3.5-5.6 III ... aperture does not work (direct visual check)


EOS ?
usable FRSP shutter speed range: ? - ? sec
lens tested: ? ... aperture works/does not work (direct visual check)

(EOS 600D - should be identical to 550D as far as FRSP is concerned)
EOS 40D
EOS 50D
EOS 60D
EOS 6D
EOS 7D
EOS M

These are the cameras I am interested in the most (the cheaper the better :) ). But you can state any camera that works with FRSP. Maybe this will turn into a useful list.

Thanks a lot and thanks to all the developers that are making this magic firmware possible.

- full-res LiveView (only 5D3 for now, but there is a PoC for 700D with adtg_gui); this can reach shutter speeds as fast as 1/15000, with a rolling shutter of 128ms on 5D3
- this proof of concept (use aperture to simulate a mechanical shutter, much quieter, compatible with all models, just need a couple of hours to make sure it actually works as advertised, then it will be live)

To select 1/8000 quickly, try the exposure presets feature. A Lua script can be used to sketch the half-shutter workaround, too. Disabling exposure simulation might be also helpful (yet another workaround).

To sum this up:

where's the needed code (parts) to get FRSP running with such high shutter speeds, e.g. 1/1000? I remember also some comments about achieving a neutral density effect. Some guidance, please, as well as a solution for triggering the hot shoe flash in frsp. Wanna achieve soemthing like this for cheap

High shutter speeds won't work with the "classic" FRSP codebase, but with crop_rec, in LiveView. On some cameras it is possible to increase the resolution to match full-sized CR2 pictures. It is technically possible to implement this capability on all DIGIC 4/5 cameras; possibly on newer and older ones as well.

As for triggering the hot shoe flash, that's the MPU territory. Apparently the decision to trigger the flash is taken on the MPU. This might be a starting point: https://www.magiclantern.fm/forum/index.php?topic=18123

I haven't analyzed the MPU firmware yet, but leegong (from Nikon Hacker, but also present here) did: https://www.magiclantern.fm/forum/index.php?topic=17596.0

There is a catch: fast-shutter silent pictures will be captured with rolling shutter. Readout time will be significantly higher than exposure time, so... if you manage to trigger the flash mid-exposure, you'll only get a thin strip on the image. At least that's what I'd expect.

You can try "leaf shutter" by changing the aperture value when capturing FRSP.

a1ex, thanks for the detailed answer.  ;D

Greg, as far as I understood, the SPT software could adjust the delay of the inbuilt popup flash. Correct me if wrong. Didn't see it from that point of view but this brought me to the idea how some radio trigge rmanufactures do it, too. They provide an adjustable delay option on their triggers and you can adjust it to your needs as described in X Contact Timing of SPT until vignetting is acceptable. probaly not worth the hassle but one would need to find a way to adjust the delay (property?) via ML.

You can try "leaf shutter" by changing the aperture value when capturing FRSP.

this one I didn't understand. Was reading chdk's wiki last days and then shocked seeing they could do some kind of 1/60000 flash sync speed.

Yes, each camera has a different x sync calibration. You can change this value, but I don't know where (prop/eeprom).
Proposed name for the module "fake_hss.mo"  ;)

A few years ago I used arduino as a shutter button. Arduino sent a signal to the camera (shutter release connector) and then to the radio triggers.
This may be somewhat unstable. In some modes, the camera has a random delay.

Was reading chdk's wiki last days and then shocked seeing they could do some kind of 1/60000 flash sync speed.
It's possible for a CCD sensor.

this one I didn't understand.
A1ex knows how to change the aperture during FRSP exposure. If you know how to trigger a flash at the right time. You can try :
- Start FRSP @ F16
- set the aperture to F1.4
- trigger the flash
- set the aperture to F16
