wstam Posted June 9, 2013 Share #1 Posted June 9, 2013 Advertisement (gone after registration) Hi, Has anyone tried using expodisc with M240? How to use it? I have tried it on M9 when I just got my M9. Didn't find the need to use it. It has been a while and forget how it was done (don't have M9 now). With the M240, the only way to measure WB is via the grey card measuring menu. From a few test shots, the WB were way off. I may have done something not correctly. Will like to see if anyone have tried it. Thank you. Link to post Share on other sites More sharing options...

Lindolfi Posted June 9, 2013 Share #2 Posted June 9, 2013 Yes, tried it and it works with great accuracy when using the greycard option in the menu item. Clouded sky 5450 Kelvin which agreed with my Minolta color meter II and the balance as measured in PhotoShop was perfect. You can also use a sheet of white paper, don't need a grey card, but select the paper on true whiteness (max reflectance). Link to post Share on other sites More sharing options...
thighslapper Posted June 12, 2013 Share #3 Posted June 12, 2013 Yes an expodisk is a good temporary solution the the flaky M240 WB. Takes 10 seconds - access greycard setting in menu , just put over lens, point at light source,shoot, then set. Accurate and simple. Easy to carry in a pocket (the neck loop is a menace is it keeps knocking into the camera). I have a 62mm which is big enough for all my lenses except the noctilux. They do 'warm' version as well for portraits thats meant to be better for skin tones but I haven't used it yet..... Link to post Share on other sites More sharing options...
wstam Posted June 12, 2013 Author Share #4 Posted June 12, 2013 Thanks both for sharing. I didn't get good result when trying it in a restaurant with mixed light last weekend. Will try again coming weekend. Guess has to point at some light sources or the brighter part of the scene. Cheers. Link to post Share on other sites More sharing options...

You would have to do a separate Expodisk for virtually each photo from the site of the subject looking back towards where you will be taking the photo from .... as the light mixture on each subject will probably be different....... unless you and the subject are static all night. It will still be better than auto WB or a fixed WB setting and will mean less adjustment in LR later. Link to post Share on other sites More sharing options...
