I think you mean Folsom. You may have a defense based on them not being able to identify you beyond a reasonable doubt. However, know that the judges in SF are notorious for finding defendants guilty even when the picture is unclear. Also, they may have access to the original digital versions that may be clearer than what you are looking at. Are you basing your opinion of the picture on the notice they sent or on the photos that are online for you to look at.
Also, they have to set the yellow time according to the statute and if it's less than the minimum, you could be found not guilty. It's rare that they don't have it set correctly, especially for long running programs like SF but I've seen it happen. At the time of your violation, the posted speed there was 25 mph. This looks like a statutory speed based on a business district but I can't be sure without further research. If so, they are legally allowed to have set the yellow at 3.0 seconds. Starting August 1st, the minimum yellow interval for a statutory or prima facia 25 mph posted road goes up to 3.6 seconds. However that probably won't help you since your violation occurred before the new rules went into effect unless you get a very understanding and lenient judge who understands the argument as to why we got the rules changed and wants to give you a break even though the new time is not required yet (highly unlikely). Also, I don't know what the yellow time is there so I don't know how close they set it to the minimum. Does any of the paperwork have the yellow time on it? On one of the pictures it might say Y=.
