    Give it a 'test drive'. Ivo keeps his eye on this tread and can give you some help if you need it.

    Here's my take. First time trying real processing.

    Apparently my laptop monitor where I did the processing is ridiculously bright - the image looks a little dark to me now on another monitor.

    First opened in Photoshop.

    I also used a graduated filter and the adjustment brush to try to get rid of the gradient.

    Looks pretty good for a "first attempt" Jason!

    Appears you were pretty much successful getting the gradients removed.

    The "lens Corrections" did move the 'spikes' a bit. (they look a little 'curved') however you did get the coma corrected.

    It's a bit dark but could easily be fixed using just a 'brightness / contrast' adjustment.

    Great Job!

    Keep your eyes open for the next "Challenge" beginning in April!
