How to create HDR images using only Photoshop layer masks

Creating an HDR image is typically involved with a quite time-consuming workflow that consists of merging, tone-mapping and post-processing, possibly spanning several different software programs.

I will show you this technique that works by creating luminosity masks straight from the images themselves and using these masks to reveal only the well-exposed parts of your exposure series.
