Now I'm sure some of you know this already. The iPhone has a setting called "White on Black" (Settings->General->Accessability) which inverts all the colors on the screen. You can set it so it's activated and deactivated by a triple click on the home button.
This function is, of course, there so you can read white text on black for better readability but I just found out that it actually makes for a decent live neg viewer. Turn on the camera, activate the function and view some negs on a light table. Obviously it only works with b&w film and not with color due to the orange mask. It's also better for medium format and bigger sizes although 35mm works, too, if you only need a basic idea of what's on the image.
This made me think a bit further. For a tech savvy programmer it shouldn't be that hard to write an app that allows for the inversion to compensate for the orange mask and maybe do basic functions like contrast adjustment. Am I wrong? Or does Apple not let iOS app developers mess with the live image from the camera or the screen image in general?
In any case, I think if someone made this app I would pay a few dollars for it. Well, actually, I think I should get it for free because I came up with the idea but I'm sure others would pay for it 😉
Such an app, together with an iPad as lighttable, would make for a very handy neg viewer while you travel 🙂
