Ah, the holiday weekend app sales have begun.

FX Photo Studio 4.2 for iPhone and iPod Touch is on sale for Black Friday. There are a ton of filters in this excellent photo app. There are filters, effects masking, excellent Instagram integration, and now the app fully supports iOS 5 and the higher resolution of the iPhone 4S. All this, and it’s still old iOS and old iPhone-friendly.

It’s on sale now for a limited time for only $0.99 — that’s a dollar off the regular price. This sale is only good for a limited time. It’s got a huge variety of filters and it’s from a great developer who regularly updates the app. It’s easily worth its normal price. FX Photo Studio is a steal for a dollar.

FX Photo Studio is normally $1.99 in the App Store. Requirements: Compatible with iPhone, iPod touch, and iPad. Requires iOS 3.0 or later.
