Showcasing a soft and diffused light quality, the image below was created using a diffused (matte) reflector. Because this type of light is not as reflective, it has less contrast. Out of the two, diffused light is a more flattering light for portraits as it does not direct attention to any one part of the subject. Typically, fashion photography use diffused light for it’s flattering and soft qualities.

INTRODUCTION: I've been working on this in the background for over a year. The Quark Aspheric Lens Kit allows you to convert your Quark from a reflector-based light to an aspheric-based light. The white Delrin reflector (machined in-house) helps generate some spill, allowing you to see nearby surroundings while throwing a ton of light down range.

This DIY trick has been floating around the internet for years now, but it is one that holds its own in small studios and independent productions. In the industry, soft frost is commonly referred to as shower curtain because it is often the same material as a common $10 shower curtain. One of the great things about this trick, other than restroom curtains often come in different capacities and colors, its that it is a very large and is able to turn an average speedlight into a large soft source.

In the video, Blankenship explains that you don’t need deep pockets to achieve a quality look, in fact, a few dollars is probably what it will cost you. He uses an inexpensive shower curtain to soften the light and compares it to much more expensive alternatives.

This kit will work with older quarks (non-MKIII) if you can manage to separate the head. They are glued shut and can be difficult (or nearly impossible) to remove.

We include 2 lenses because the front of the aspheric is slightly proud of the bezel. Nope, not ideal, but an engineering limitation in this application. If you use the light a lot, you'll need to replace the lens eventually, and we have you covered.
