Undoubtedly, one of the most critical aspects of digital photography or videography is the consistent control of color.  The color values recorded by a camera's sensor need to be matched with the color palette of a monitor, and the eventual output device as well.

The Color Balance Lens (CBL) is a 2-sided disc with a gray side and a white side, to handle your needs of color balance and proper exposure alike.  You use the white side for color balancing, and after the white balance is achieved you use the gray card for an accurate exposure reading.

Adjusting color balance with digital cameras varies, but in every case you hold the CBL in front of your camera and either make an evaluation or take a white-balance-reference picture.  You should assure that the subject's dominant light source is also falling upon the CBL.  Thanks to its complex, varied collection of prisms and lenses upon the 'white' side, the CBL grabs a large mixture of the light source and directs it into the camera during the white balance evaluation.

You are not reading light reflected off of subjects, and in this way the CBL is consistently more accurate just as incident light meters are more accurate than reflected light meters.  You are not evaluating the white balance from a flat reflection of a gray/white card, which cannot gather as relevant a 'recipe' of reflected light from complex scenes.  While white/gray cards or lens-attached white balance devices often yield fine results, it is in the most difficult lighting scenes where the CBL's design shines best.

To use the gray side for evaluating exposure, you simply use the CBL's gray side just as you do a gray card:  use your camera's spot or partial metering mode if applicable, and place the CBL's gray side in your subject's lighting source.

    Color Balance Lens - 110mm Large Disc is rated 4.7 out of 5 by 28.
    Rated 5 out of 5 by from Great for tricky lighting situations. Works great for mixed lighting situations; and is quicker to use due to the fact that I can leave my camera in auto-focus mode while taking a reading. Easy to use, (but) the instructions could use some editing as they are overly wordy. When I tested the results in my studio against the standard gray card the color balance was even better using this device. The time you will save in post-production makes this a real time saver and worth the $

    Rated 5 out of 5 by from Color Balance Lens - review All I can say is buy this product. It works great. I use it for portraits inside and some outside work. Once I balance my camera I'm all set, just shoot. Make sure if you have any default or set custom white balance, it's set to all zeros for the white balance to start, then do your shot and set the balance picture of the CBL. It seems to work best if you get a good close up shot of the CBL, not angled to one side which can produce glare in the white balance picture shot. Make sure to read the manual entirely to get the best results. I can't say enough good things about this product, very satisfied.

    Rated 5 out of 5 by from This thing really works !!! After reading a number of reviews of the CBL, I finally bought one. I was skeptical about all the claims and at the time very satisfied with the other white balance devices that I use... After receiving the CBL, I compared it to some of the other devices (e.g., ExpoDisc, WhiBal) and the CBL performs better than all of them. Especially in low light, when good white balance is hard to come by, CBL continues to work very well. Yes, I was surprised -- but also very satisfied with the CBL (it now goes with me everywhere)...

    Rated 3 out of 5 by from Initial disappointment After researching this product I believed that it would give me accurate white balance for ambient exposures made under artificial lighting. One of my regular shooting locations is a ballroom with a very red color cast. My CBL Lens arrived earlier this week. After reading the manual and watching the included video disc I attempted to make an accurate white balance in the ballroom. I shot the white side of the lens from a variety of angles and in several locations throughout the room; I used different lenses; I even tried using the grey side for white balancing. All of my 'white balanced' exposures came out looking like they were shot through orange Jello. Finally I just gave up on the CBL and switched to Kelvin mode and dialed all the way down to 2500K, and that gave me the most accurate scene rendition. Don't take this review as my final verdict; I might have been using the device in too extreme a lighting condition to get the proper results. However, since I have seen nothing but glowing reviews about this product I felt an alternative perspective might be helpful.

    Rated 1 out of 5 by from Not Recommended. I have really mixed feelings on this product - it came highly recommended from the reviews online and a workshop session endorsement with Hanson Fong and I wanted to like it.HOWEVER, in field experience with it leads me to think the $ is better spent elsewhere, and the net, net is I returned it. Read on for the long summary.For the record I used the 110mm version as a custom White Balance on a Nikon D700 and as a post processing aid (Hanson uses a Cannon - maybe their whitebalance isn't so good ;-). I tried it with single light sources and with multiple light sources (daylight mixed with incandescent. With daylight, shade, and green canopy overcast, etc.). For the most part I used the white side only, ignoring the grey side (I don't need more grey targets).So here is the good and bad in summary:The Good:1) Looks more professional and high tech than most, cheaper white balance solutions (this doesn't matter to me, but may matter to you - it gets mentioned a lot in the reviews).2) Occasionally produces better white balance in limited situations than a grey card, expodisc, or color checker passport. This is a subjective statement, and the degree to which it was better didn't warrant the cost or size for me.The Bad,1) The instructions are HORRIBLE, they mostly consist of product endorsements from Asian Professors. Essentially they state that you can use it in standard mode (taking a flat of picture of the disc) or Flood light mode (this is never explained but appears to me and angled shot of the disc). Nor are there any good instructions online in YouTube or other places. I went looking because my results were not impressing me, and I figured I had to be missing something somehow. Something in the manner of it's use after the fact Post processing the magic Flood light mode. 2) The results are inconsistent. Some times the white balance is spot on and some times it wasn't as good as the other methods (Grey card, presets, etc) I compared it to. For what it is worth this may partly be because the model I had hold it in the various shots may have held it differently each time, but then that is part of it isn't it? I also found the result pretty inconsistent when I held it at arms length. So this isn't a one stop shop, you are going to have to tweak white balance.3) It's large to carry and store. For me, I prefer more portable solutions. For example a collapsable 10 or 24 grey target for example, Color Checker Passport, etc), and Expodisc (these have a different set of pluses and minuses)4) It's expensive.5) It is unclear to me how durable the white side is - if scratches in the plastic lens cover would effect it's performance for example since it is claiming to rely on prism effect.Overall it wasn't something I found worth carrying or owning.

    Rated 4 out of 5 by from Expensive but product delivers. This product delivers what it advertises. Color accuracy is superb, leading to no necessary corrections in image-editing software. It is expensive. The instructions are poorly translated and unnecessarily wordy. If you don't get the results you have in mind using one side of the product, turn it over and color balance from the other side. Your specific lighting situation matters as to how you proceed with the product.

    Rated 5 out of 5 by from Nice product I am a Canon 40D user. The auto white balance on the 40D is great in all of the basic modes. The 40D creative modes allow settings such as color temperature, shade, tungsten light, fluroescent light, etc. These also work pretty well, but not as well as I'd like. I purchased the CBL lens to make the white balance better whithout going to Photoshop when shooting in the creative modes using the camera's custom white setting. The CBL lens works great once you get used to using it. The real color really pops and I do not have to do much work on the shots afterwards in photoshop.

    Rated 5 out of 5 by from Unbelievable - very reliable Used this product right out of the box, skip the PowerPoint, look up you camera in the book and follow easy instructions. Indoor, outdoor color is spot on, great for mixed light environment. If you don't like the initial read, set it up again, it takes 3 sec, and usually the second exposure will be spot on. This is an accessory I bought on impulse and I'm glad I did.
