First of all I would like to warmly thank you for going to read this post , having said that I proceed with the item in question.
I have a camera Canon Powershot SX700HS and saw that they had a version of CHDK for this, my problem is the following, as I understand it to be able to install the software I have to go to an option called firmware update which does not exist in my camera so thank all aid on the part of any person , thanks in advance.
I have the 100.e firmare version.
