Yet Another Sunset Script (yass) v2

[Lamerjack]

Thanks for the script, i'm going to give it a try while camping next week.

btw, on my SD870is without a viewfinder button, i force it off by putting a headphone plug in the AV port.  simple and effective.

Syncros, nice idea!!!! I will try to see what happen hotpluggin the jack during timelapse to see if there are problems.
Regards.

Really enjoying this script - I hope you don't mind but I've made a couple of personal changes that I thought I'd post back.

The attached file uses get_tick_count to more acurately calculate the delay between shots (for example extended shot time does not extend the delay as it does in your script)

I've also added the power saving extra of turning the backlight off during the delays between shots...

I've also modified it just slightly. I made it an option to have the backlight on or [mostly] off. I moved the command to turn the backlight off so it is off for more of the time. I also added some print commands that  are a little more helpful (to me) for monitoring when the script is running and backlight is on. These can be removed for the highest framerates possible.

I also wanted to mention that this script works well to keep the focus at infinity with the backlight off. The focus has to be set manually though! I know it is set in the script, but it doesn't seem to work. I like that I hear very little clicking and the screen only shows up for a moment after each shot.

edit: on testing with lower delays, the backlight doesn't always turn off. I'll test more later but where flipper321 put it the screen turns off consistently.
edit2: went looking for fbonomi's original to see what changes were made in yass and if there was any other useful background information from fbonomi. i was surprised to find that he put essentially the same information I add for configuring  I'd suggest keeping the print statements so the script is a little less mysterious.

Hi!

munk_e, Can you post the exact line that turn off the LCD, to put it in other script, please?

Can anyone tell me what is the difference between this script and a intervalometer script (like ultra intervalometer)??

Thanks!

I used the "set_backlight" command
set_backlight 0 turns it off (use 1 to turn it back on)

It seems to work fine where I moved it, but I think I should apologize for not realizing the intent of YASS. speed = cutting out PRINT and REM lines! I'm thinking a script with 2 modes, a default mode with original print statements, and a mode for highest fps, will be best

I will use this starting tomorrow and we'll see how it goes for nearly continuous shooting over 50 hours! 1 frame/3 sec and unloading the card every 12 hours

Hi!

Thank you for this script, however, I can't get it to work in my Canon IXUS 80IS (1100).

When I run the script, the camera take the pictures, with a delay of 2 seconds, but I've configured the Limit Tv to -384 (16 secs), however the speed of photos are between 1 and 2 seconds (with any light, is the same)

I have this exact same problem on my SX200IS, no matter what I set the Tv to, it seems to be making exposures of about 1 to 2 secs.

Any ideas?

EDIT: To answer my own question, the problem was I was not in Manual mode on the camera.

Further I see that I need to set the Aperture manually as well.

Now it is working basically fine on my SX200IS. I haven't tested all the features, but basic shutter and ISO controls are working great.

I basically followed all the advice in the readme.txt for sunsetF16.lua which is also in this forum, turning off IS, the focus assist stuff, I manually set the focus to infinity as well.

Thank you very much for a great script.

I recently finished putting a video together with YASS. You can see that I set the threshold for guess mode too low and the highest ISO a little high. However, it worked brilliantly! No focus problems at all, very little noise (just the closing of the shutter, no focus sounds per shot) and it runs stable for about 12 hours when the card memory runs out (8GB). I used a Canon A590.

munk_e: can you post your edited YASS for the 590is? Im still learning Thanks!

You know... I was fiddling around with a lot of things but I didn't end up making any meaningful changes. I attached the script I used in an earlier post. The backlight might save a little battery life but choosing good batteries or power source is probably more effective anyway. In the end, the most important thing I needed to do was set the variables correctly, since the purpose of my video was very different from a stationary point of view.

The working scripts people post tend to work across cameras (the exceptions to that I couldn't be sure of, sorry!) and for this script I found that I really had to study the language and commands used here to configure it, it's not all that intuitive to me. It's been awhile since I looked at this stuff though, busy life you know? The worst of it, for those of us learning, is that the information is scattered in a lot of places!


Also (not sure if this applies to anyone really) I remember an issue with the script going through the guess mode for a 2nd time. The compensation factor doesn't reset, so if you go light>dark>light>dark, the second transition to dark will use the last compensation factor that was determined, which could make for a very abrupt transition. So for most people, this would never come up unless you are shooting through two nights without shutting it off.

I shoot 17651 images with the script during the last weekend, one shoot every 10sec, the night shots were unusable because the camera tried to focus on every lowlight shot.  I had the focus setting at 3 (inf)

do you know how can I leave the autofocus disabled?

[munk_e]

try a different shooting mode and make sure it is not focusing for each shot when you start the script. I used Manual mode and set focus to infinity in the normal interface to be safe and it never tried to change focus
