How to I get the Instagram "Lux" effect without using Instagram?

  • I am kind of fascinated with the new Lux effect of Instagram. I want to "get" the same effect myself, during post processing. This is what I was able to get to, after playing with Levels, Contrast, Saturation and Shadows in iPhoto.

    My questions:

    1. Is it possible to get such an effect using basic tools like Picasa or iPhoto?If so, how?
    2. Is it possible to get such an effect in Photoshop/PS Elements/Lightroom (and the like). If so How?

    With the Instagram Lux effect and "Low Fi" filter: Photo with Instagram Lux effect

    What I could get: (at best, with my limited knowledge) photo after playing with Levels, Contrast, Saturation and Shadows in iPhoto

    I'm not familiar with Instagram; is it possible to show the effects of the Lux effect and the Lo-Fi filter separately? I don't know where one ends and the other begins, and it might be easier to deconstruct each on its own. (Someone previously analyzed the lo fi filter here).

    @mattdm - Typically filters in Instagram can only be applied one at a time. In this case, Lo-Fi is the filter that can only be applied at one per photo. Lux is a secondary option that isn't a "filter" according to Instagram, it is kind of like a button to just bring out vibrancy in any filter. So to answer your question, yes it would be possible, but they have stacked the two here in the examples.

    So, here's what I got in just a few minutes using two basic tools: Curves, and Unsharp mask:

    replication attempt

    I used Gimp, but this is basic stuff any decent image editing software will have. Here's all I did. First, I used the curves tool to dramatically increase the black point, increasing shadow contrast:

    shadow contrast up

    Then, I pulled the curve upwards to brighten the (new) midtones:

    more midtones

    I didn't mess with the color channels at all; this is all the global "value" curve. I made these adjustments by eye, watching the tone of the house as I worked.

    Having done that, I resized to 612×612 (the size of your Instagram example here), and then used an Unsharp Mask with a radius of 10 pixels and a very high strength.

    This doesn't look exactly like your image, but I think we're in the ballpark.

    There's a sort of glow over the lower part of the house that's missing, and I couldn't replicate this with global adjustments without destroying the tones in the sky and the detail on on the tree branches on the left; I suspect that the filter applies a graduated vignette/glow/"light leak" effect somewhere in the pipeline here. If you compare the top half of my attempt to the Instagram output, you'll see they're really close; the difference is in the lower part.

    The original has flat lighting; this fake burst is part of what adds dynamic interest, but which also feels a little bit like cheating: Instagram is not just capturing what's there with a funky filter, but altering the reality of the scene.

    Update: this is with just an upsharp mask with radius 100 and strength in Gimp of 2.0 (Photoshop measures strength differently, but basically, about 10× higher than one would normally use if going for a natural looking image).

    with just unsharp mask

    The curves approach gives a lot more control and it's still what I recommend, but for quick and dirty replication of the effect, this might be all you need.

    _This doesn't look exactly like your image, but I think we're in the ballpark._: Man this *is* what I wanted. I did not want to create the *same* as Instagram, I wanted to know what/how that thing was being done. Thanks for explaining step by step... I learnt many things today. Awesome!

    If you step the Unsharp Mask radius *way* up (to the ~ 100px level) there's no need to touch the curves; UM does the tone forcing for you.

    @StanRogers It's true; that might be all there is too it. The effect in the example is really strong, and I was hesitant to bring the unsharp mask strength up that high.
