On my recent trip through Estonia I did quite thorough testing and experimenting with Android Vignette app on my HTC Incredible S phone. All and all this area of “iPhoneography” seems to be getting to be quite relevant and interesting area of photography as mobile cameras are now reaching acceptable level. Being forced to use focal length of about 30mm constantly really forces you to think about what you shoot.
My initial impressions or mini review about Vignette app is positive. It really adds the usefulness of mobile camera, and as such is easily worth the money.
But anyway, below you can find some real world Vignette app sample images from my trip:
