Ultimate Intervalometer - a script for shooting over a long duration - v4.9

Hi Waterwingz, I tested the new v4.5 script but I still had the same issue (sets taken at same shutter speed). Could the issue be that I was using it in a relatively bright room with sunlight? I'm saying this because I tested the 4.5 version yesterday and today in an indoor room without direct sunlight and it worked. The log file is attached. Please see at end of file right after I started using the v4.5 script.


Thank you,
Belal

So in a bright shooting situation, the sets are all the same shutter speed.  Did you look at all nine images to confirm the exposure was exactly the same on each? 

Not that it should matter - I tested with a brightly lit outdoor scene and all nine of my images had different exposures.

Well, I guess that's a bit of progress.  Prior to this nothing worked on your cameras.


edit : version of the script with expanded HDR exposure logging attached.  Please try this and post the log file?

I'm running this version now and will post once completed. Does the fact that the hot shoe of the camera was used affect the functionality of the script? I tested it with and without, seems to work without it. This hypothesis is still under testing to be confirmed or refuted. Any thoughts?


Thanks,

IIRC, anything fully inserted in the hot shoe could cause problems.  I believe doing so has been shown to disable CHDK's ability to override exposure settings - at least for some ports.

See : Using CHDK Commands and Operation for Hot Shoe Flash and Problems overriding shutter speed on SX40 for a couple of examples.

This was discovered some time ago and a fixed tested as a side effect of this forum thread : Flash hot shoe - override the switch.

An optional CHDK menu item was added such that cameras with a hot shoe also have a menu choice in the CHDK Enhanced Photo Operations menu called Hotshoe Override that allows you to disable the sensor switch in the hot shoe ( the switch that detects when something is inserted in the hot shoe). 

So far, it's only enabled for the G7, G10, G12, SX10, SX20, SX50, and s5is.  And not for the your G15 (or my G16 for that matter - or the SX60).  It might make sense to add to these cameras too but doing so requires someone to do some testing on the actual camera to figure out which bit in the I/O in the keymap is the HOTSHOE_FLAG.

It all makes sense now. The hot shoe sensor was causing all the trouble. This is a bummer because I needed to attach a sensor to the camera using hot shoe slot. Thanks for explaining this!

This should be easy to fix, the required values are automatically found but haven't been verified. I posted a test build for g15 100e over in the porting thread: https://chdk.setepontos.com/index.php?topic=9257.msg133592#msg133592
Don't forget what the H stands for.

I have had a few issues with my Canon G9 which is now running the CHDK software. What I did is I built a compartment for the camera to be located outside. I have put fans in to stop the camera from overheating and when I tested it there seemed to be no problem with cooling. It is currently running the ultimate intervalometer script, however I have had the following issues:

1. My smaller concern: The camera is not allowing me to use the full 32 Gb of my SD card, it is saying that I only have 19 Gb free even though the camera is empty?
2. My biggest concern: My camera stopped taking photos after around 1.5days as soon as it was getting dark. What could be the issue?

Does it do this when you do not have CHDK loading? (i.e. set the SD card switch to unlocked prior to starting the camera)

Please attach the log file created by the script (ULTIMATE.LOG) to a post here and I'll take a look.  You'll find it in the top level folder on your SD card.

I was seeing that the SD card was full when I plugged it into my laptop. However when I saw how many photos I could take from my camera, the issue was still present.

2. Do I have to take out the SD card from the camera if I want to view the log file? Thanks very much.

Your G9 will not autoboot with that large an SD card unless it has two partition, each formatted a little differently.  What method did you use to setup CHDK on your SD card? What method do you use to load CHDK?

Practically speaking- yes.

However, you can view the file with the CHDK file viewer.  But it's much too large to do anything useful that way.  And I won't be able to see it to help you.   You can also upload the file to a PC over a USB cable if you have chdkptp on your computer.
