>> other wise you can end up wih very blue or orange photos, that cant be fixed in post.

Either it can be fixed in post, or it can’t be fixed by the camera too, since they are working on the same data.

I’m able to use two stacked polarizers (one linear, one circular) in place of a ND filter which gives a very very strong purple/blue tint to everything and still fix it in ACR in like 10 seconds.

I swear by my Expo Disc, using a 77mm for all lenses is the best way to go. Have both the ‘warm’ and ‘neutral’ and have just abandoned the ‘warm’ in favor of more natural skin tones of the ‘neutral’ filter. Using coffee filters, other papers just won’t cut it for me. As well, it can help with exposure determination if you don’t have a light meter.

Alot of Arena’s in my neck of woods are changing out the lighting to LED .I believe it would be cool but not sre.My Nikon d300s has no setting for such lighting and even Nikon had no view has to what setting I should try.Yet again another flaw with Digatel that seems never to happen with my F5.

If you read this far . . .

The real answer is to use a target, NOT the Expo Disk or similar device.

A Whi-Bal Card (the best) or the equivalent, will work on all lenses and all lights, like on camera flash and light tents. It only costs $35.00. Is non breakable, clean able and very fast and very accurate.

Even if you shoot RAW, you need to have a KNOWN neutral in your shot, IF you want accurate color. You can always adjust for TASTE, once you are accurate and can batch file process both for accuracy and taste.

It can also be used to help set contrast and custom white balances.

To the people who say who cares about the white balence, fix it in post – photoshop does not make the photographer. Spend time learning your craft, white balance is important, other wise you can end up wih very blue or orange photos, that cant be fixed in post.

Raw is not an excuse to be lazy or take crappy shots.

I own the Expodisc and It works great. I just put it over the lens, point it at the light source and I am good to shoot in raw or Jpeg or both. If you are using a small light Tent? Duh, take the reading off the white inside the tent before you ad anything inside of it. Its the color of the light you are measuring right? I have learnt many tricks with it too…. I have used it as a Light meter and on occasion I have put in on the lens and aimed it directly to night city lights and have captured the perfect color balance on the first shot. I own photoshop and I love “not” to spend hours in post processing when I can balance the color in camera in a 5 seconds or less.

Todays cameras color balance is way better than it used to be but for older cameras…. Just get a reading on the sun or light bulb or whatver the light/lights sources are and then chase after the kids with abandon whout having to worry about color balance.

When you shoot in raw did you know that most of the times if you color correct the midtones your whites and shadows may still be way off? If I want perfection RAW is just the begining and as with any tool…. it is only as good as the person who is using it. I like the whibal idea…. I could color balance darks, mids and whites and contrast range all at once…….. so I probably will try it next.

with mixed lights? guess what…. use it to balance right in between color temps….. for special effects…. for example…. I have color balanced between a light bulb and a white TV screen…… then I photographs a black item… oh the beautiful orange blue color effects with basically ….. no special lights

Just some ideas… have fun.
