[/caption]If you have ever read a photography article or book about getting sharp pictures you would know that there is always a section about using remote shutter releases. The IR remote shutter releases are more popular online while professionals rely on using the good old cable ones. So I went online to find out what a simple cable and plug with switch would cost? The cheapest one was for 900INR which is a lot to ask for just a piece of wire. I can do better. :) So I decided I would make my own.
The cable release typically involves getting a connector the brings out the contacts of the release button. From these, three contacts are going to be used- Focus, shutter release and common. In case of Canon EOS t2i and related models, a pin connector is used. The schematic for the canon t2i is given below.

What we did was to use a simple push switch which was most appropriate for handheld use and bought it from the local spare part vendor because cost was the first constraint here. We then added a smaller push button by gluing it to a convenient location where it will be easily usable.
I also added a simple burg strip using super glue and made the connections to the switches and proceeded to add connectors to the cables as necessary. I am not going into the details of the other connectors as they are irrelevant. I wanted to be able to use the same cable to connect a microcontroller to control the shutter for an intervalometer project but that I will cover in a different post.
A little soldering later, the result was a cheap sturdy cable that can be used with the T2i at a fraction of the cost.

Good One.. but does it works with 1000D.. I doubt

Umm. I am not sure but as per information provided to me, it should... Maybe you could confirm whether yes or no...
