There are so many things a photographer (professional or hobbyist) can do to improve the end results of their photos, but one tool I have used for over fifteen years that never fails is my Expodisc White Balance Filter. It is accurate, easy to use, and creates a much more natural tone to my portraits and photos which means less time color correcting in my post-production workflow. 

It's very simple to use. First, you'll set your DSLR white balance settings to custom (this varies by camera - see your user manual for directions). Snap the filter on to your lens, make sure your lens is on manual focus and take a photo with your camera FACING your light source. Your light source can be whatever is providing light for your photos. Don't point your camera right into the sun or anything, but you get the idea. You can also point it towards your external light source. Make sure the flash triggers, and then set the image (it will look white or slightly grey) as your custom white balance for this scene.  

Remove the filter and replace it in the pouch, reset your camera lens to auto focus if that is how you plan on using it, and you are ready to go. 

Some additional reasons for using the ExpoDisc 2.0 White Balancing Filter:

• SAVE TIME FIXING COLOR - set a custom white balance to get beautiful color straight from your camera - stop wasting time fixing your color later with software 
• EASY TO USE - the ExpoDisc is easier to use than white balance cards, gray cards, and photographic calibration targets - simply attach the ExpoDisc to your lens and set your camera’s custom white balance 
• QUICKLY SET WHITE BALANCE - just attach the ExpoDisc to your camera’s lens and follow a few simple steps to set the white balance - in most cameras you can set a custom white balance in just 15 - 20 seconds 
• METER FOR 18% EXPOSURE - ExpoDiscs are individually calibrated to transmit 18% light - this produces a gray frame reference that can be used instead of a photographic gray card to establish an 18% exposure 
• MADE IN USA - we care about our products - we assemble, calibrate, and certify every ExpoDisc in California - 1 year warranty
