ExpoDisc 77 mm 2.0 Neutral and Portrait Balance Filter - White

I have always used white cards for colour balance with mixed results. Depending where the card was placed and the angle in relation to the light I would often get a colour cast, so I'd try again....and again. Using this gizmo takes only seconds and the result is spot on first time, every time. I even tried it with an ND filter attached the lens and again got a perfect result which I never could using cards. The only thing I've found is if using indoors, whilst the colour balance is bang-on, the exposure it suggests gives an image way too bright once the Expodisc is removed and the shot taken (about 2-stops) however shooting outside it's spot-on. Maybe I'm doing something wrong with the indoor usage but it's not a major concern as I just adjust the exposure back 2 stops and I'm good to go. BRILLIANT product - everyone should have one!

I saw a review comparing this to a cheap Chinese one and the results are not surprising.I think if you use a DSLR and you are wanting to take your pics to the next level, this is a must.If like me you ever used a light meter, this is basically how this works....Remember the inver cone light meters? incident and reflected readings?Cameras all take reflected light meter readings which is why they don't always work well, the old analogy of a white wedding dress in a white backdrop or the groom in black against the dark interior of the church, difficult to meter, incident readings are taken from the subject toward the camera, its the light coming to the subject and is the most accurate way of taking a reading.So you place the disc over your lens and take a reading looking toward where your camera will be. Thats an incident reading.The WB issue is also a must for digital users. OK so your not going to use it all the time, but those pics you want to be impressive, keepers, you will benefit from this. ie, sunsets if you ever took any sunsets and were disappointed at the result, the colours will not be as strong, why? because auto WB will try to rectify the light which is approaching the red band of the spectrum and correct it. Using the disc will give a setting for the true WB at the scene, the colours in the sky should then show up as you saw them, also use the disc at that time to take an exposure reading, as, that is also something difficult for your camera to expose for.I have tested this under some fluorescent lights and noticed my 60D gave a magenta cast in auto WB with the disc I didnt, I got pure white, the shot had a whiteboard in it. I wouldn't have seen the magenta cast to be honest with having used the disc, is was the true WB of that pic which showed up the magenta in the auto WB shot. I would say its worth the money, its seems to be calibrated and certified etc, also a nice lanyard and pouch and no light leak, like the Chinese copy I saw a review of. In this kit you get 4 filters, they are 2 of each +1 and +2 blue gels. These are for portraits.Why blue? because the disc will correct the colour in the blue gels thereby making a slight warm tone in your selected shot with the gel on to select the custom WB.'Update' after having this for a couple of years, I lost mine, so got another, they come in a silicone pouch now so even easier to get in and out,I have a G7X2 now as well as the DSLR's and I had a go with that, Canon dont make it as easy as some to set up a custom white balance but its fairly intuitive and once you have selected a menu option at least its there next time you go into the menu.I didnt bother deselecting auto focus on the G7X it coped ok, but the results are quite astoundingly different especially under different light.I think best that can be said is, if youve ever looked at some shots and thought, there is something not quite right, its good but not amazing? I would say usually the missing link is white balance is off. I took some sample pics of some plants in a window against the light and used both the white balance setting and the meter setting of the disc, the camera was then telling me that the settings were way out when I took the shot, but although the window was blown out, if I cropped the picture to get the plants it was perfect, true colours and well exposed.If you have been reading this and your considering the disc, give it a go, it will take a few practice shots to get it right, its a workflow thing but the results will amaze you.If there is ever any dominant colour or a general 'hue' in the shot, like taking a family shot against a brown shed in the garden, your camera will try to compensate for the brown shed, or if lots of people wore blue in your shot, you see auto white balance only has what the camera sees to determine a colour temperature.

These are very good and in my opinion superior to a grey card. You need to learn how to use it and understand that it is for incident light and not for reflected light. In some situations this will not matter but if you are stood in bright light and the subject is in shade or is lit with different light your reading will be off.For colour this is very accurate and it can also be used to set your exposure - watch the you tube videos.overall very quick and accurate to use when you get used to it and very good for getting things right in camera when the lighting is mixed or a little difficult. Yes you can do this in post but this is a better solution for white balance and tint in one hit.

Excellent product. Really helps me get consistent white balance - vital while shooting events. You can use it smaller lenses too, just have to hold it by hand. Ideally take the lens hood off before taking a reading, in my experience.What I've been doing at events is making sure I have at least one shot with the correct white balance in every lighting situation. After that point it doesn't even matter if the others in that situation aren't set to that preset balance, as that can be simply be synced across in post-production (as long as you shoot RAW).Occasionally I have to shoot at very high ISOs at events and getting the white balance right from the get go helps get cleaner images with less colour noise. Try it!Very pleased with this, and happy to answer practical questions...

very good at what it does ,ie give you a neutral white balance, not always the most pleasing effect however ,which is why we take photos during the golden hour ,it works very well far better than a grey card or white card, you will struggle with on camera flash unless you can bounce the flash off a wall and have it come back at you as it reads as an incident meter would by pointing it at the main light source . Fantastic for weddings etc when you need white balance spot on.Build quality, the first one was better in my opinion being made from an alloy , but they have dropped the price by a third with this plastic one ,is it more accurate well that worked to 18% grey also so cant see how . On the whole a must for all photographers you photos will look a lot better out of the camera especially if you shoot in jpeg .Raw well we can change the white balance post production but its great to start right .if they went back to the metal version then it would get 5 stars .

Used this thing to white balance (3) cameras for a multi cam shot and everything matched perfectly . So much better than using the grey card.

Lo he usado poco aún, pero me parece genial y fácil de usar

Simpel aber extrem effektiv.Passt auf (fast) alle Objektive. Aufstecken, in die Hellste Lichtquelle fotografieren, Bild als Weißabgleich festlegen, fertig.Toller Support, Tolle YouTube Videos und Hardcopy Anleitung. Was will man mehr als Fotograf.Alle folgenden Bilder sind in bester Lichtfarbtemperatur und Weißabgleich wie man es brauch. Man spart mind. 10 min je Bild bei der Fotoshop Nacharbeit.Für mich ganz klar unverzichtbar. Müsst ihr haben!!!

If you need to get your white balance accurate in the click.. go for it. Remember to be set your white balance against light source not targeting to your subject.

Je suis amené a prendre de nombreuses photos de sport collectif et de gymnastique.Mon ennemi : l'éclairage des gymnases !!!Je ne parle pas des éclairages cycliques qui sont une vraie plaie lorsque l'on prend des photos de sport en rafale (heureusement, les boitiers reflex modernes gèrent ce phénomène), mais des couleurs en fonction du type de lampes utilisées et des grandes baies vitrées qui font entrer de la lumière en fonction du temps qu'il fait dehors (jaune ou bleue selon l'ensoleillement).Avant, je me baladais avec ma feuille A4 blanche que je prenais en photo afin de calibrer ma balance des blancs. Je devais refaire cette manipulation plusieurs fois dès que les conditions de lumière changeaient à l'extérieur.Aujourd'hui, j'utilise l'ExpoDisc que j'ai découvert grace à des forums photo sur lesquels il était plébiscité. Et bien je ne regrette pas l'achat. C'est nickel. La précision de la balance des blancs est juste incroyable et il est très facile d'utilisation.Bref, je le recommande vivement.
