WOW! That's incredibly beautiful.
Thanks.
I only used the RAW from the cam, developed with DPP and made the video with VirtualDub. No farther processing on this video.
What aperture did you use?
I used f5.6. All parameter can be seen in the log file in Reply #365 and the AV value also in the plot (OK, the scale is bad for this information).
This is another great think about rawopint. Everything gets logged for later investigation. Ok I added the temperature of battery.
My plan was to run the script into darkness but I forgot that the size of RAW Data was about double as on my G1x so I run out of memory with my 32G Card.
I have one 128G Card but if I want to use it on M3, I have to format the card into FAT32 (If I understand correctly).
Did you use a filter?
No. I was already afraid to use no ND filter. With my G1x it is always switched on when I photographed against the sun. But the sun was already very low. In a higher sunshine I would not do it with the M3. The sensor temperature remained below 45 degrees Celsius (I know the temperature is an average and not a spot). At the G1x I had runs that went up to 80 degrees Celsius with no problems.
Have you ever changed the ND filter of the G1x with your time-lapse in the script?
I've attached a copy of rawopint.lua with set_sv96(sv) replaced (at line 1055) by the code I've been using for years without problems. Will you see if it fixes the ISO problem on the G1X if you have time? Run the script in continuous mode.
-- *****lapser sv test
-- set_sv96(self.sv96)
set_prop(props.DELTA_SV,self.sv96-get_prop(props.SV)+get_prop(props.DELTA_SV))
set_prop(props.SV,self.sv96)
-- *****lapser sv test
I always run in continuous mode…
I think this is what we have discussed here
https://chdk.setepontos.com/index.php?topic=11081.100and have tested here
https://chdk.setepontos.com/index.php?topic=12165.msg123576#msg123576But I will try it on the weekend with your modifications again. Do you use only RAW or the JPG from the cam?
I did my first time lapse with the EOSM. The script just holds the shutter down in continuous mode with 20 second exposures at night, but it works.
It is really great. I'm really jealous about these…
Unfortunately I live in a region with a lot of light pollution. Have to do long trips.
Which ISO do you use?
You used the EFM 22mm. I would prefer wider angle. I have an EFM 15-45 and an EFS 10-18mm. But both lenses have a great initial aperture. I’m thinking about Walimex/ Samyang 12mm F2.0 or 14mm manual lenses.
I'm working on other scripts too, using reyalp's fantastic hook code.
Interesting. Hope we hear more about this.
Basically I am very satisfied with rawopint. Sometimes it gets in oscillation (especially with waves). In this case, I am able to fix it
https://chdk.setepontos.com/index.php?topic=12790.0I think it is possible to fix it in the script but I haven’t found the time to go deeper into it.
Perhaps interesting information of the M3. In fast mode (stay in half press) the aperture can be changed (not in continuous mode). This could be used especially with time-lapse in the transitions day to night and vice versa. I wanted to try out a long time, in which steps the aperture can be changed. Probably but not as with the ISO in 1 / 96EV steps.
How do you power the M3?
