Product Description

Size: New - 77mm

Whether shooting in RAW or JPEG, photographers using ExpoDisc to white balance their images save valuable time in photo editing software. When used to set a custom white balance, the ExpoDisc consistently produces excellent color in natural, artificial, and studio lighting, and it even excels in difficult mixed lighting environments.
The ExpoDisc is far easier to use than any gray card, white card or calibration target. Simply place the ExpoDisc in front of your lens and capture the incident light while setting your camera's custom white balance. Using an ExpoDisc custom white balance will virtually eliminate the need for RAW or JPEG post-capture color adjustments.
The ExpoDisc is not just for white balance, though. The precision calibration and uniformity of the ExpoDisc means that it can also be used to meter for an 18% incident exposure and to produce a dust map of the image sensor.
To meter for an 18% exposure, stand at the subject's position and aim the camera back towards the intended shooting position. Use the camera's meter as seen through the viewfinder to adjust the aperture, shutter speed, or ISO until a proper exposure is indicated. It's also possible to make exposure adjustments based upon the position of the histogram spike on an ExpoDisc test shot. Simply adjust the aperture, shutter speed, or ISO until the spike is centered.

Features:
* Combines both (Neutral and Portrait) versions into a single tool
* Quickly set white balance for photo and video
* Meter 18% Incident Exposure
* Dust Map Your Image Sensor
* Hand Calibrated for Accuracy

Contents:
* ExpoDisc 2.0 Professional White Balance Filter
* Comfortable Lanyard
* Sturdy Carry Pouch
* Calibration Certification Card
* User Quickstart Guide
* Selectable Warming Filters
* 5 Pc Cleaning Kit

Customer Reviews

I was questioning if I should actually spend this much money to purchase this disc.

Because in order to use the ExpoDisc effectively, you have to set the custom white balance every time the light situation changes.

Expodisc only cares about the color of the light source, so it only removes the yellow cast of the incandescent light.

Size Name: ExpoDisc 77mm
I don't remember how I came to learn about this tool, but I bought it in a store for my Nikon D300 without reading any reviews. I did try it out in the store and I was immediately impressed with the results so I bought it on the spot.

The disk is amazingly well packaged. It's packaged just like an iPod that I received some years back. It doesn't have the scrimpy, we-don't-care Made-In-China feel. It comes with a lanyard, a semi-rigid pouch that you can attach to your belt, a CD with all of the PDF instructions in multiple languages and a how-to video.

Their web-site also has instructions on how to set the Nikon D300 pre settings.

For years, from the time I got my first DSLR I've been plagued by color balance issues. It seems that I have to color correct each and every photograph in Photoshop. I shoot in RAW so that I have more control but it takes so much more work and time. I'm also not very good with color correctly with PS. I have all the instructions and I follow them carefully, but I always had problems getting the hang of it.

I own gray cards but they're bulky and I don't walk around with one. I also haven't had very good luck with them either. I'm sure it's my technique but I never did get the hang of it.

Shooting under artificial light is a real pain. Auto WB never really works.

I first tried the ExpoDisk in a room lit with CFs (Compact Fluorescent) bulbs. I used the ExpoDisk as directed and I received absolutely perfect results the first time. Then I tried another room lit with LEDs. Again, perfect results. I put a Gretamacbeth colorchecker chart in each of my test shots. Every time, the whites are whites and the blacks are black. Zero color cast.

If you struggle trying to "fix" your images' white balance after your digital capture, this item is your answer. Put it on over your lens, point it toward the dominant light source (such as that funky incandescent / fluorescent light mixture in most homes), take a photo, and set the Custom White Balance in your camera. That's it! I have captured photos using home/indoor lighting, stage lighting, etc. NO MORE TWEAKING WHITE BALANCE IN PHOTOSHOP! It's dead-on every time.

I take this with me wherever I know there will be mixed lighting and use it before I photograph. You will be impressed as I am.

Size Name: ExpoDisc 77mm
I read a lot of reviews of the expo disc and decided to give it a try. It is so easy to use and the results are sooooo much better than auto white balance. Like anything else in this world, it is only a tool; it doesn't do miracles. But, when it is used correctly, it helps make your photos look fantastic. Initially, I hated having to pay $100 dollars for it. I thought, "What a rip-off for such a little lens" But, after I saw the results I quickly realized how valuable it is to me. Once you get accurate colors, you'll never want to go back to auto and presets again!!! Imagine being able to shoot jpgs that have correct color. I hate shooting Raw because the file sizes are huge and there is always the extra step of converting them to a format that anyone can view. When I use the expo disc I can get the color right the first time and not have to sit in front of a computer tweaking the color of thousands of photos! Even if you like to shoot Raw, it still saves you time because you won't have to edit the white balance on every photo taken indoors.

This is a lot more convenient than using a gray card and it is more accurate.

Size Name: ExpoDisc 77mm
As other reviews have already said, this thing is accurate and convenient when dealing with mixed lighting or when you just want a dead-on white balance.

For me, it's greatest strength isn't actually the fact that it gives you an accurate white balance - there are other products that can do it, too. It's about how FAST it is to use this.

I also own a PhotoVision Calibration Target and an X-Rite ColorChecker Passport. While both of those play their own role, neither hold a candle to how fast you can use the ExpoDisc, and on a fact-paced shoot (ie: wedding day), speed is key. Pop it on the lens, take a picture, DONE. Change lighting - pop it on, take picture, DONE.

Usually, I don't even bother setting custom WB in-camera. I batch apply the WB of the still ExpoDisc picture to all the photos that follow in Lightroom. When I get to a new picture taken using the ExpoDisc, I know to apply that new WB to the next batch of pictures. SO EASY.

As a side note, you don't need different sized ExpoDiscs for your different lens sizes. It works just fine to buy for your biggest lens and manually hold the disc over smaller lenses.

Size Name: ExpoDisc 58mm
This product works amazing. Currently in my photo class we are going over white balance and we did some testing. we shot a gray card (has black, 18% gray, and white) and set that as our custom white balance and it worked good. We then shot just the 18% gray. We then used the expodisc and the results were almost night and day. The white balance was perfect. the whole class was amazed. the ease of this product can not be surpassed, your shots will come out noticeably different. I would whole heartedly recommend this product to anyone who is shooting digital.
