ExpoImaging ExpoDisc 77mm Digital White Balance Filter - Neutral

I wrote a glowing review of the Whibal card not long ago, and while I still use and really like that item, I also enjoy using my Expodisc. When I'm not using flash, it's quicker and easier than my whibal because I simply put the disc over my lens, point to the light source and shoot. I've found both the Expodisc and Whibal to be excellent white balance tools.An added benefit, for me, is using this as it was originally marketed, which is a basic incident exposure device. After using it this way, I must say I'm impressed with how much more accurate my exposure's come out as opposed to relying on the reflective metering and histogram reading inside my camera. I'm sure more sophisticated (and expensive) meters would be even more accurate, with better functionality, but for me, I'm thrilled not having to spend as much time in Lightroom trying to fix the arguments my camera has with the software program as to which exposure reading is correct. Of course, I try and stay out of it, but usually side with Lightroom, as it has a monitor to prove its point.....Luckily the ED has done a good job of helping them kiss and make up.This doesn't mean I still don't take some bad shots....I absolutely make errors (especially with flash) that make my camera and computer team up on me where I have to sleep on the couch. However, I'm a happier guy these days with better white balance and exposure from the get go.If you're needing an excellent white balance product that you can use everywhere and won't cost you a lot of money, but you want something with a bit more research and engineering behind it than a napkin, then the Whibal card is hard to beat. As I said, I love it and use it when I'm taking studio shots and also when I'm using flash.If you're needing an excellent white balance device that's a bit handier to use when you're on the go, I've found the Expodisc to be great. I know, I can't carry the Expodisc in my wallet like I can a Whibal card, but I also can't carry my camera in my wallet either, so usually when I have my camera, I've got the ED handy via lanyard. As I've already noted, getting an incident exposure reading is nice too. Especially when you're trying to take photos under multiple light sources, with natural light not being one of them. After trying a recommended Pringles lid, I'm glad I opted for the Expodisc.Like the Whibal, Expodisc took the time to make a professional website with helpful video and written descriptions on what the disc is for and how to get the most out of it. I appreciate details like this, as I want to know what I'm getting and how to use it properly before I'm going to spend money on it. I also like the hand-documented calibration measurements I received in my Expodisc box. Nice!I can now see why so many people rely on the Expodisc, and highly recommend this to anybody that's been on the fence and overwhelmed with which white balance product to get. My personal recommendation: Get a small Whibal card you CAN keep in your wallet, and get an Expodisc you can wear around your neck when your planning on using your camera and you're constantly changing photo subjects. Whether you get one or the other, or end up buying both, you'll be getting a very nice and easy to use white balance tool.Disclaimer: I don't really believe my computer and camera have feelings, nor do I think they want me to sleep on the couch....But if your camera could talk, what would it say????

I'm a semi-pro photographer and I was looking to speed up my workflow, particularly with weddings. I was using auto white balance in camera and color correcting in post processing. You can imagine how time consuming this process was. I saw several photographers recommend this product and I was skeptical. After a few sessions my verdict is: it really works!!I use it to take my exposure reading first, then custom white balance on my Nikon D800. That's it. You can change your exposure and don't have to take another white balance. If you change areas or the light changes, you have to take a white balance reading again. It takes a little practicing just to get fast with it. It's worth the 30 seconds it takes. The color is spot on and I don't adjust white balance anymore. I get that done during the session or event.You can take the white balance by standing where your subject will be standing and pointing the camera where you will be standing OR by pointing the camera towards the primary light source. In my experience both methods worked. I find in a shaded area, it's best to point towards the primary light source so that your white balance isn't too warm. Some people get caught up in the exact method, but really either works. You can watch video tutorials on their website.The other benefit of this method is that I can show a quick preview to the client from my camera and the photo looks really nice. Not all cold and dark like it would with auto white balance. If you're debating getting it, just do it! I must have for semi-pro or pro and good addition for photography lovers. I would order again without thinking about it.

So I got this little disc, because Kevin Carson a Photographer at Samy's Camera recommended it. It seemed like a good solution to accurate white balance. I was going to use it indoors and outdoors and in museums. The fact is it only really works for outdoor sunlight. If I use it for indoor lighting the colors come out wrong and are not accurate. I use to constantly change my white balance using the Kelvin system and fine tune it with the color grid. That works but it's time consuming. If your looking for an easy solution this seems more complicated then it's worth. Using the Kelvin system and modifying your color gird is what I recommend don't waste your money like I did.

This is an exceptional filter if you have IR converted sensors. I gave it a 4 out of 5 because the filter doesn't adhere to the lens or lens filter very well, so when in use you have to watch it when you tip the camera down, or ensure that the lanyard is affixed to the camera somehow to minimize the chance it will fall off when you tip the camera down. Yes, this filter isn't cheap, but if you do IR work it will be worth the investment, gives fairly accurate CB, and is much easier than using WB card. The only thing easier is to take a shot of fully lit, actively growing green vegetation for your custom WB shot.

Well the product does work as advertised. It gives you very accurate custom white balance readings. The problem is that you have to shoot the sample image back into the light source, which is not always possible to do unless you are in a studio or controlled location shoot. For scenics it is not very practical. I used it a few times but it mostly sits in my bag now. It's too much money for something that you don't use because it is a hassle. I am open to suggestions from other users if I am making it unecessarily complex or am misunderstanding how it is supposed to be used.

I found that it worked very well but at a venue it was not always easy to stand in the right position to get a correct w/b reading.Make sure that you purchase the largest one available so that you can use it with all of your lense

No es la ultima version del articulo que incorpora dos geles filtro para fotografia de interiores y nuevos diametros de objetivo.No obstante,cumple su funcionamiento basico.

En Exposition 18%, très bien; en balance des blancs, et multi-éclairages, pas évident à utiliser correctement...Article de bonne facture, j'en suis globalement content.

Was will man viel zu der Expodisc schreiben? Es ist ein super Teil für den Weißabgleich und kinderleicht in der Handhabung. Einfach vor das Objektiv halten, Kamera in Manuel-Focus umstellen, dann einmal in Richtung der Lichtquelle die das gewünschte Motiv belichtet knipsen. Mit diesem Bild dann den Manuellen Weißabgleich in der Kamera einstellen. Expodisc wieder abnehmen, nicht vergessen den Autofocus wieder einzuschalten und dann kanns losgehen.Erwähnenswert ist vielleicht noch die Verpackung. Die Expodisc kommt in einer Schachtel in der ein hochwertiges Nylonetui enthalten ist. Das Etui hat eine Schlaufe mit dem man es am Gürtel oder sonstwo befestigen kann. Die Expodisc ansich befindet sich bereits in dem Etui, sowie ein Halsband das man, wenn gewünscht, an der Expodisc befestigen kann. Weiterhin hatte ich eine Testkarte mit dort drinn, auf der Handschriftlich die Testwerte der Disc eingetragen sind. Jede Expodisc wird von Hand auf ihren Grauwert getestet. Meine erreichte 17,90% von den Perfekten 18%.Mehr gibts eigentlich nicht zu sagen. Der Preis ist leider recht hoch wie ich finde. Dafür bekommt man aber ein wirklich nützliches Teil und braucht keine lästige Graukarte mehr mit sich herumschleppen. Von dem Gedanken das im Fotobereich überhaupt irgendetwas "billig" ist hab ich mich sowieso längst verabschiedet. :D

Je viens d'acheter cet article suite à de nombreux avis favorables sur les forum photo pour le réglage d'une balance des blancs correctec'est effectivement bluffantPour ceux qui comme moi se demandent s'il s'agit bien du modèle neutre (le plus polyvalent) ou du modèle portrait (plus chaud); mes messages à avides ne m'ont pas permis d'obtenir une réponse à cette question avant l'achat, ce qui est surprenant compte tenu que l'indication est clairement écrite sur l'emballage.J'ai donc pris le risque et surprise, c'est le bon...Envoi rapide et bien faitles meilleurs prix de web françaisla plus mauvaise désignation produit (aucune pour ainsi dire, et pas en français ni en anglais ...)je pense que ce commentaire aidera de nombreux photographes à acheter ce produit expodisc neutre, et avides à en vendre un peu plus ;oà acheter sans hésiter
