agrokid Posted April 30, 2012 Share #1 Posted April 30, 2012 Advertisement (gone after registration) The big, square lens hood on Digilux-2 doesn't suit round ExpoDiscs. Take the lens hood off? Very difficult with my deformed fingers. I know I could use a WhiBal card, but I'd rather get the capture right in the first place than adjust in post processing. Perhaps all I need do is keep a sheet of translucent white plastic in my pocket, maybe cut from a domestic food container. Even with my dodgy fingers I could probably hold the plastic in front of the lens with one hand, and click with the other. Has anyone tried something like that? Who knows, it might even function as an incident light meter - but I'm getting carried away now. Better walk before run. Link to post Share on other sites More sharing options...

Blindjock Posted May 1, 2012 Share #2 Posted May 1, 2012 The digilux 2 has a white balance sensor on the case front (in line with the shutter speed dial. I don't know whether it also uses data from the ccd but I would guess so. Link to post Share on other sites More sharing options...

My preferred method is to set the WB in camera by shooting a calibrated grey card (ColorChecker or WhiBal) at close range in ambient lighting. It holds good and accurate until you change location or the lighting changes. If so, repeat the process. Easy! Simplifies post-processing. Just check the method of doing this with the D2.

jaapv Posted May 1, 2012 Share #4 Posted May 1, 2012 Ummm... As far as I know white balance on the Digilux2 is set by the double sensor on the lefthand side of the camera, not through the lens. That makes an Expodisk rather useless for the purpose. The camera is has one of the best WB systems anyway, it does not really need such things.

I learn something new every day. "..one of the best WB.....does not really need such things." Well it has never yet let me down, but when I read all the trouble other people go to it makes me feel I should be doing more. Well now I won't. Unintentionally this thread has produced yet another reason to keep my D2. It really is an astonishing little camera. Thank you for your help, Jaapv.

That makes an Expodisk rather useless for the purpose...... Jaapv, I think of you as virtually infallible. However on this occasion I believe you are wrong. Leica Digilux 2 Instructions Page 129 shows how to do what I described above. On screen you see: 'POINT THE CAMERA AT THE WHITE SURFACE AND PRESS SHUTTER'. My white surface is a WhiBal or ColorChecker card. I find the latter rather easier to use 'in the field'. So it must be working on transmitted light, not what an external sensor sees.

mija1789 Posted May 1, 2012 Share #7 Posted May 1, 2012 Advertisement (gone after registration) Jaapv, I think of you as virtually infallible. However on this occasion I believe you are wrong. Nope, he is 50% correct. There is indeed an IR sensor for the WB on the left hand side. But the other sensor is not a sensor. It is the self-timer LED.

jaapv Posted May 1, 2012 Share #8 Posted May 1, 2012 If you point the camera at a white surface, you point the WB sensor at a white surface at the same time.... And yes half the double window is a selftimer LED. I see I formulated confusingly. I used the description double for easy identification. Sloppy.

Hi, Just set the white balance on my D2 manually for the first time by putting a piece of white card in front of the camera as per instruction booklet. As I too have problems with my fingers and constantly lose things in my pockets when out walking I cut out the white paper and 'stuck' this on the back of the lens hood cover, which because of it's size I never lose. Probably would be more accurate with calibrated grey card cut to size. Hope this helps. David Welcome, dear visitor!

DavidE Posted May 7, 2012 Share #11 Posted May 7, 2012 It is probably too small for accuracy. Hi Jaapv, Point taken. Quickly took these indoors hand held - no tripod (apologies for images out of focus) :- First image taken after manually setting white balance from A4 white sheet Second image taken after manually setting white balance from close up of back of lens hood covered with paper from same A4 white paper attached. I was suprised to find that this quick test under artificial light showed very slight tonal change, but to my old eyes no significant difference. David Welcome, dear visitor!

jrethorst Posted May 10, 2012 Share #12 Posted May 10, 2012 The D2 manual, in the section "Manually setting the white balance", p. 129, says: "Aim the camera at an object that you know is white or neutral gray. It should fill the frame in the viewfinder/monitor." This suggests that white balance is measured through the lens in addition to the sensor on the front of the case. I've had good luck with an Expodisc clone (same size, about $10). I set the zoom to 90mm and hold the disc in front of the lens, filling the frame in the viewfinder.
