"Meters" .... does anyone use these?

If you have an iPod Touch or iPhone, would you be interested in using it to measure the Visible Light Transmission (VLT) percentage? I just completed an application called ‘iTint’ , and should be available in the Apple App Store by the end of August 2009.

So how can it measure vlt without a 'known' light source to measure from ???

Maybe you measure the light coming through a non-filmed window followed by a filmed unit. :cool That would give you the comparison if you figured that the first was 100% (we know the glass removes some vlt, but for the test this would work) and then the second would be based on the reduction from the first. I do not know if that is how this app will work, but that might be one way. I am assuming that it will take the measurement with the camera? :lol

I don't have an issue with what you posted, you post stuff like this all the time, I was referring to Sarah chewing us out about your snapping film for back windows thread.

sorry when I said that, I ment the way you eye sees things or percieves things. psychology is the only way a app like that would work...like the card trick the post before. where they talk about the diamonds only being able to be seen at certain darkeness. that is psycology ...the same as point perspective....

Actually the light source is the bottom half of the screen, which you place behind the tinted glass. The top half you adjust the brightness to visually match the bottom. Works great to measure relative brightness, I.e. you can get a number that let's you determine which object is darker. Of course everyone's eyes are different, so it's not 100% accurate. I was able to get some measurements off some samples I had using a Phantom Visible Transmission meter for the VLT, but the numbers are off using my app. This could be because the measurement of the VLT% is done on the entire visible spectrum, not just one color.

the cops have a card, in fl, is 35% and the card reads 35% in a light grey color broken up
but only in dimond shapes

if tha film is darker than 35% he can not see the dimonds

:embar you would think they could afford a meter. I guess just like us, law enforcement is looking to save as much money as possible.

it would be much better as a windows mobile media app.. than a apple app...why lock it to apple...booooo-thumbs down...there is so many people that have other mobile media phones/pocket pc's....

One advantage Apple has is that if you have an iPod Touch (which is not a phone) you have no monthly charge. If this idea works, then it will be ported over to other mobile devices, like Blackberry, Palm Pre, Android, and Windows Mobile. Apple makes things easy for independent developers, unlike some of the other companies.
