Yesterday I posted a tutorial on frequency separation from Elena Jasic. In case you missed it you should go check it out! Well today she hit me up to tell me she had quite a few questions still regarding the preparation of the layers for frequency separation, so she made a handy little action, and asked me to pass it on to all of you. Who doesn't like free right?!
You can download the action here: http://www.elenajasic.com/Actions/FrequencySeparation-ElenaJasic.zip
Now a quick note, Elena designed this action to work how she does her work flow (and coincidentally how I do mine as well). This action will work flawlessly if it is the first thing you do upon opening your image in Photoshop. In other words, this action will work perfect if you perform it when you only have the Background layer. Select that layer (since it is the only one you have) and run the action, and voila! You have your frequency separation layers set and ready to go. Now go check out the tutorial one more time for a guide on how to retouch using these layers.
