@Edgargraphics1 Glad to hear it. Thanks for your comment!

hello with the grey card do you take a picture filling the hole frame of the photo like you do with the white cards?

[MarleneHielema]

@xsjad0man No, you just need it in the same light as your subject. So if a studio portrait, I face the card towards the main light and if a landscape, I hold it at arms length myself and take a shot. I have examples in the blog post cited in the video description.

The grey card also sets white balance

[khashy87]

from which of the automatic white balance should you take the costume white balance from a gray card?

[MarleneHielema]

@khashy87 You can use the grey WhiteBalance card (if it's big enough). I don't typically use it that way though, I sample the WB card after the photo has been taken. I find the WB grey cards more accurate than using a white card for custom WB. Have a look at my related blog post in the video description.

if i shooting in RAW do i need that on location? or its just fine to set up on my computer? for my white balance.

[MarleneHielema]

@calizormc Yes, you need to shoot the white balance card in the same light at the same time as your other pictures. If the sun goes behind the clouds then do another WB card shot. Refer to the blog post (in the video description) that explains the process in detail.

[MarleneHielema]

@calizormc Yes, On location. Take a photo of the WB card at the same time you're shooting the rest of your pictures. Use it as a reference later when you get home and start editing your photos. Works best with RAW files. If you shoot only jpgs, then you might want to use an ExpoDisc or set up "in-camera" custom WB. That just takes a lot more time that shooting the card.

Interesting, never realized that. Can I use any old grey or white card? Where do I get these cards?

[MarleneHielema]

@cruisinaltitude Thanks for watching!

Check the blog post in the description above for more info on the types of white balance cards available and where to get them. 18% grey cards are available at any major camera store, but you don't really need one if you use your histogram and use exposure compensation.
