ExpoDisc Professional White Balance Filter - 77mm lens thread - Get Beautiful Color in Your Photos and Video, Easy-to-Use, No Software Required, Save Time Fixing Color

Gone are the days of holding a white card up to my subject and framing it for custom white-balance. What a great idea! I have only one piece of usability advice: If like me you setup your camera to always display current set exposure (i.e. you set your viewfinder to follow how dark or light your exposure is prior to pressing the shutter release), when you place the ExpoDisc over the end of the lens you may need to temporarily adjust your ISO or aperture to let in more light to compensate and allow your camera to read the disc properly. Otherwise you may receive an underexposure error when trying to set a custom white balance. When your WB is set you then need to reset your exposure settings back to where you had them before. If, like most people, you do not set your camera viewfinder display to follow your exposure settings, then this is not an issue. I know this can be confusing. What I mean by "follow your exposure settings" is that your viewfinder will darken and lighten according to your settings. I am not referring to the settings information, such as ISO, SS, Aperture, and so forth that is displayed. This is predominately an option in mirrorless DLSRs such as the Panasonic GH5 and Canon RP cameras, but can also be an issue if you pre-stop your iris in other mirrored-cameras or when using fully manual lenses with on-lens iris control. While it sounds complicated, its really a no-brainer and is still a lot easier than using a white card.

I knew I would love this product. I heard about it, I read about it, I watched videos about it, and I priced it. I generally shoot jpg because I don't do a lot of editing. If you shoot raw, another choice would be to use a gray card but if shooting jpg, do this as part of your initial setup (aperture, shutter speed, ISO) and images are perfectly white balanced out of the camera.It does what it claims to do and some of the things I really liked about the 2.0 version:1. MADE IN USA (this is very important to me). The originals were probably made in China.2. I stressed out about which one to buy when I learned about the first models but the 2.0 is currently only available in 77 mm size (removing one decision I had to make about which lens to buy it for). They have always recommend buying the biggest size though.3. The other issue on the original was that there were two versions to choose from, an general use one and a studio version for portraits. The 2.0 is only available in what I would call the general use version. They have added a filter pack so that if you want to warm up the WB for portraits, you layer the included filter gels on the ExpoDisc (maybe when I take my annual Christmas card photo, I will mess with the gels).4. The 2.0 is about half the cost of the original (also very important to me).I am pretty sure this is the only thing I've ever rated 5 stars. If you were on the fence about buying one, jump off because this is definitely worth it. I will probably end up getting another one for a spare because I don't ever want to be without one of these. Seriously.PS - I shoot on Nikon D7000

Way better than a balance card!. With a balance card you have to make sure you tilt it in the right angle to get a good read....annoying espcially if you have 2 or more different light sources with different color temps hitting the subject you are photographing(like indoors where not all lights are equal).This is meant to be the size of your lens or larger so dont try and find anything smaller than the 77mm. For example i have a 72mm diameter on my 24-240mm lens. I bought a step-up lens adaptor from 72mm to 77mm to accommodate this ExpoDisc and then bought a lens cap for that step-up adaptor.I love this thing because of the prism element in the front and the 2 portrait warming addon filters just to give it a slightly warmer look(very subtle and not at all over done)when you want it. Its not metal like the first version but due to its use(constantly on and off so I like the durability of a good plastic) keeps me from scratching my lens frame and camera frame when constantly detaching and reattaching.Just watch the videos on YouTube. Trust me. Get this thing if you are even remotely serious about photography from new hobbyist to extreme pros. And stop annoying yourself with guessing the right white balance or using the auto white balance.Tons of expodisc youtubers with Nikon and Canon. I have a Sony A7s ii and if you need any pointers with using this disc on a sony a7s or a7r. Email me. I tested this thing every which way. And i dont mind helping [email protected]
