Guys

I have just become the proud owner of a £3 white balance lens cap from Ebay!!!

I have tried it today and I wonder if anyone can answer a really stupid question???

When taking the initial image (with the cap on) to use as the customer white balance picture - what WB setting do you have the camera on??? And does it actually make a difference???

Confused!!

that works?? wierd...
anyway it shouldn't
the WB is the processing that goes on from the 'normal' that comes into the camera
warmer or colder
so when you take the pick and decide that 'that' is white..then you just set that as the custom
afaik the original setting shouldn't make any difference

Set the lens to manual focus
Put cap on
Point at light source not subject
Pre 'preset WB' until it flashes (in a Nikon anyway - you may call it something else RTFM ;))
Fire of a shot on auto exposure
If the top-plate flashes 'good' (on a Nikon) the WB has been set

REMEMBER to reset the lens to auto though, or your next shots may well be OoF

Soz to labour the point - but it's really easy on my Nikons, and I have no idea how to do the same on your Canon - hence RTFM on how to set it to read a WB shot :)

Dave,

My understanding is that Canon's use the NTSC system (never the same colour) so white balance doesn't matter:lol::lol::lol:

what he said - infact it is so quick - you can do it every 10 shots, or from room to room etc..
 
It's a good question, and I too found it hard to get a definitive answer when I got my Ebay exposcap.

I have found this apparently taken from the Expodisc manual, it's #3 your looking for.

From the expodisc instructions:


White Balance Using Flash
1. Determine Exposure
2. Select Manual Focus on the lens and Manual Mode on the camera
3. Set WB to Auto
4. With the Expo/Disc attached, using flash, aim at a neutral middle value object and
make an exposure using the reflected white light provided by the flash to record a gray
frame.
