White Balance – Using a Fun Lens Cap to Get Better Photos?



This is the baLens, a fun new product I just tried out, from the PhotoJoJo Store.  It looks like a combination between a lens cap, UFO, and just strange piece of plastic.  But after seeing these results, I think I may need to order one for each of my lenses (or at least one in each size…)  And because I think that, I emailed them and asked if they could do a discount for my blog readers (and me – LOL).  I got a reply that said, “So glad you liked the WB Lens Cap!  Here is a discount you can share with your readers to let them get 10% off their order of anything from our shop through February 28th.  Hope that helps!”  YAY!!! So in case you “need” these as I do, the code is mcp4255 (enter on shopping cart page)

So now let me show you this white balance lens cap.  You attach it to your lens, instead of using your regular lens cap.  That way, wherever you go, you have a way to white balance in seconds.  The two shots above are some of the shots I took with the cap on and were used to do custom white balances as I played.
Here is the actual cap:


But more importantly, you want to see what it could do, right.  I just went to my kids’ bookshelf and took the same basic shot in the same lighting.  First I did a custom white balance using this new tool.  The color looks great to me.


Then I took a shot on Auto White Balance.  My 5D MKII has decent AWB but still not as good as the CWB shot in my opinion.  This is subjective. To me, this AWB shot looks slightly cool but not too bad…


Then for fun, I decided to try all the other settings.  This will help you understand what each does as you see how it makes this shot warmer or cooler.  I hope this helps you understand White Balance a bit more.  Please add your comment on which white balance version looks the best to you.  I love to see how others see the world of color.  And it will be fun to see the variety of responses on what people see as the “best.”

    I am excited to know about this product. It sounds a lot easier than other white balance products I have bought and used. You and your website have really been a blessing to me!

    Fantastic! I currently use a 77mm expodisc but how nice would it be to just have the cap serve the same, yet easier, purpose – then there’s no excuse for not setting custom WB (I’m always like, “ugh, where is that thing!?”) Thanks Jodi!

    I have the ExpoDisk and never really figured it out. This looks so much easier!
    Thanks, once again, Jodi for pointing us in the right direction.

    It’s a smidge hard to tell without seeing them side by side, but I definitely think that the AWB is cooler than the custom. I’m going to read up on that little gadget…sounds pretty neat.

    I hate to ask a stupid question…but here goes…

    So. You set your camera on custom white balance. Place the cap on and snap with the cap on.

    Then, you take the cap off.

    Do you have to set something on your camera or does it just remember the previous shot?

    I can’t imagine it is this simple. Are there other buttons to push and levers to move to get the cwb to stay put?

    Thank you


    p.s. I have a nikon D80

    Yep – this “cap” literally fits like a normal cap on your camera. You have to buy the size that fits your lens. You leave it on, turn on your camera, shoot. Then you set your CWB from the menu – and tell it to use that exact photo.

    Then you set your WB to CWB so your camera knows not to be on auto.

    Until you tell it a new photo to use – or you take it off of CWB setting, it will stay put.

    By the way, I just wrote up a more extensive White Balance post with different photos and more explanation for PW. I literally just sent it to her via email. So I would say within the week, you can see some more detail there.

    Hope that helps,

    Thanks Jodi. Guess I better read my manual cause I do not understand what you are talking about with the cwb. I don’t think my Nikon has that setting. It may be called preset. But I don’t know how to take the picture and use that picture. Off to read the manual.

    Thank you so much for posting this on your site. (I found your blog through that Contest with the EYES….one of my friends had submitted a picture!!) This is one thing I really need to learn about this year! I always just put it on Automatic and go on! But after seeing these pictures…you sold me on it!! I purchased mine last night and can’t wait to get it! The customer service was AMAZING at this place. I had see something like this in the past but they were like 100 bucks and I got this for around 54.00!!! SO I am really excited!!! I will be back later on to get me some of those WONDERFUL actions of yours!!! Can’t wait!!!

    Thank you so much! Can’t wait to learn a little more….
