A new iOS photo app: Subjective

We have a new iOS photo app out that combines some features of our previous apps.   The basic idea we have been pursuing for a while is based on the subjective refraction test from optometry where a person uses their own judgment for which of a set of things is better.  A/B testing is a more randomized version of this basic idea.

We first have you pick a category of editing (e.g., is it an outdoor landscape or is it food or do you want to make a stencil version like the Obama HOPE poser?).   It shows the image being edited as a background:

Pick one of the filter families-- like Stencil

Now three screens of choose best of 4:

Now pick best of four 3 times

And voila!

And here's the product.

You can of course go more conventionally and adjust contract and color temperature and saturation (one screen for each).  I like this for food.  Here's before:

and after.   Is it better?  I think so, but it's SUBJECTIVE!
