Bubble Fu is a professional image editor that turbo-charges the Photos app by adding tons of new features ranging from filters, brightness/contrast controls, blur and focus controls, clipping/cropping and more. *Features* Bubble: creates a fun illusion that tricks your mind into seeing people naked - when they aren't! No nudity, but extremely NSFW. It's a dirty mind test, a dirty minded optical illusion. Filter: The filters option within Bubble Fu works mostly like the camera filters / Instagram filters. You can pick from a bunch of popular filters like vignette, process, sepia, noir, mono, invert etc. and apply them on the photo. The previews are shown under the photo in small thumbs. Adjustments: this is where you can adjust three major features of the photo: brightness, contrast and saturation. Each one is a slider control so you can set the desired value by sliding up/down the controls. Effects: Effects, at first glance, seems to be like filters but actually, its more pronounced and crude. Effects include things like gloom, pixelate, posterize, highlight etc. Theyre not filters. Blur and Focus: Probably more technical then other features that Bubble Fu brings to the table, Blur and Focus lets you control the strength and the depth of focus on the photo. There are three modes of focus/blur that you can apply (normal, circle, band). Rotate, Clipping, Resize: all these impact the orientation, size or the crop-factor in the image. Curve: Curve is tonal curve, more like the Levels/Curve filter in Photoshop. By setting the points and tweaking the curve on the graph, you can alter the tone of the photo. Emoticon, Text: All these features let you embellish your photo with stickers or emoticons or if you want to write something over the photo, with text. You can configure the size, orientation and the font variables (font face, size, color etc.) for text. There are a lot of emoticons to choose from.
