Do you generally have an amplifying glass helpful when you require one? Me either. However, I generally have my advanced mobile phone with me, and I'm speculating you do as well. A magnificent free Android application called Magnificent Magnifier transforms your telephone into a lit amplifying glass!
With Magnificent Magnifier you can change force of the amplification and turn the light (your cam's blaze) on or off as required. It's practically as basic as that! You can download Magnificent Magnifier free of charge from the Google Play Store.
There is awesome amplifying glass application for iPhone clients too. It's brought Over 40 Magnifier and Flashlight and you'll see it on iTunes. It isn't free on the other hand, however at $1.99 the cost is genuinely sensible as I would see it.
