I have been working on my custom made variable interval timer for long exposure photography and now have all the initially planned functions working and have added a couple features. I consider it a fully funtional proof of concept/prototype. I have searched and have not found anything like it except for hardware that depends on your cell phone to provide the interface and computing power, mine is completely stand alone.
The current feature list:
- shutter speeds from 1 second to 4 hours in the standard single EV progression
- timer to support the camera’s built in long exposure(dark frame) noise reduction (currently Pentax only)
- trigger focus of the camera
- field adjustable settings
- starting exposure
- number of exposures
- enable/disable dark frame noise reduction
- save 1 set of settings
- recall saved settings
- use current settings without saving
- Known to work with Pentax(tested)
- Should work with Canon(untested)
- basic help screen
Potential future features(subject to change):
- long exposure noise reduction support for Canon cameras
- support for other cameras that have a wired remote connector
- ability to save more than one set of settings
To be able to confirm support for Canon cameras, I need access to one that has the 3/16″ remote connection to test with and determine how long the long exposure noise reduction exposures are, the save to card speed of the camera with a slow memory card, etc.
If someone is interested and has the technical skills to make one themselves, they should contact me.

We went to Las Vegas, Nevada for Christmas. This was taken on the drive there from Reno.
This panorama is build from sixteen HDR photos. I will post more from the trip as I complete the editing process.
I was just reading an interesting article about High Dynamic Range Photography at The Art of HDR Photography Part 1: Guides: Learn: Digital Photography Review. The author provides a very through walk through of the details of the technique and why it can be useful. I have worked with some HDR images using my Canon A720IS with the CHDK that I referenced in an earlier post.
This image is one of my attempts with HDR images. The difference from the original files is in the shadows within the building and the additional detail in the shadows and the sagebrush.
I achieved an interesting image by combining some night shots in downtown Reno. The visible clouds and the bottom of the river are enhanced by the combining of the images.
These and several other HDR images that I created are at my office live photos, here are thumbnails of them.
I plan on doing more of these images after I get the new camera next month.
