This may amuse

I dont think it will work, as when the photos are 'inspected' the film reader can change the film to a negative all that I have seen and played with come up recognisable.
This little story may ammuse though...

We had a memo come into our office the other day. g0551p Apparently, four aussies saw a camera van, three of them went up to it and spoke to the PC inside asking all kinds of technical questions on how the system worked etc... The fourth chap, with screwdriver in hand, removed the index plate from the van. This number plate was put onto one of their cars and they drove through the speed chech and activated it seventeen times. %$fan :beer:

Because, the reading system was automated no one saw the photos therefore the camera partnership recieved seventeen speeding offences. I dont know how true this is but we've been told to monitor the indexes from now on :xm more bloody paperwork!! Oh and we musn't talk to strangers LOL

Totally agree with Messer.. None of the so called anti-gatso sprays/plates do anything at all !
I have repeatedly experimented by taking pictures myself and seeing if the plates can be read..
the closest to work was the 'FlashBack' system.. the gatso flash triggers a couple of slave flash heads mounted beside you plate.. It over exposes the picture.. But even that is only a very low grade maybe !

I dont know about the technology Gatso uses, but any half decent photographer knows that if you want to be sure that the film retains the information you require then you should by default under expose it.

Also, dont be fooled by how easy it is to create overexposed shots with your own camera, if you used a cheap (less than ?50 per print) photolab then they would not have bothered to try and compensate the photoimage for the negative exposure.

Im sure the Gatsos know this and you will find that in order to force a total overexpose then you will need a lot more light than can be achived by a partial reflector.

What would be cool is an LCD overlay on the numberplate connected to a slave flash unit, that would turn dark should the slave flash be triggererd.......

I presume that any any light thats shone on it causes a glare,hiding the numbers on the plate.Im wondering about if plod was following you at night and saw that your number plate was obscured by glare of his lights he would work out that something was dodgy about your plate.?

Take a close look at the pic of the back of the Merc on the ebay ad. Photochopped if you ask me. Plus you'll also note from the glare on the boot that the flash is far brighter in the second pic.

There's only one totally foolproof method of avoiding the Gatso on a bike (aside from editing your reg plate) and that's to cock your right leg back so as your boot covers the plate as you go through the trap. If you practice it somewhere safe you'll find that you'll soon be able to accurately place your boot over your plate within a second.............

The 'ol 'hairspray on a section of your plate' trick rapidly attracts loads of road filth and will totally obscure the section applied to...............

...had the same pipe-dream thoughts about LCD plates but trouble is the slow response time of LCDs. By the time it'd changed the photo will have long been taken.

In fact, I've never quite been convinced by any claims for active systems that are triggered by the gatso flash. The system would have to do whatever it's trying to do in the time remaining between the flash hitting it and the camera's shutter closing. Anybody know this time (Messer)? Say 1/25th of a second? And, the active system would have to be able to do it's stuff for as long as it's needed to be effective.

So, let's say if the active system's aim is to flash it's own light at the Gatso to bleach the negative then it's going to have to do this within the 1/25th of a second including the delay in the system's electronics: Detect Gatso flash -> activate system's return flash -> keep flash lit for sufficient time to bleach negative. All this in 1/25th of a second sounds like a tall order to me. But then maybe somebody with better knowledge might prove me wrong.



The LCD shutters as used in welding masks would be the ticket as the react within milliseconds the only problem being is the intensity of the light needed to trigger them being equivalent to a welding flash at close range is way beyond the output of a gatso flash. A far better solution would be to trigger your shutter from the buzzer or warning light on a GPS based warning system that way latency is not a problem, the whole setup would be simple to setup and only cost as much as 3 or 4 speeding tickets the downside is if Plod sees it in action you will most likely get done for obstructing a policeman in his duty or perverting the course of justice :eek:
