gee-bug Posted October 5, 2003 Share Posted October 5, 2003 I bought a used Luna-Pro Digital F today at the Denver "Camerama" show. It came with a quick reference card, but didn't have the full instruction manual. I've figured everything out except for the "COR" mode. I know that it is for exposure compenstion, but I'm not quite sure how it works, e.g., what does "rF" mean when you push the "M" button? Any help on this or other tips and tricks about this meter would be greatly appreciated, thanks. Link to comment Share on other sites More sharing options...
Rob F. Posted October 5, 2003 Share Posted October 5, 2003 Ken, I've got one of those. As soon as I find the manual I'll let you know for sure, but I think it is for "corded" flash exposure. That is, the flash unit is connected to the camera with a cord, as opposed to a wireless slave unit. Now let me go rummage for the instructions.

Rob F. Posted October 5, 2003 Share Posted October 5, 2003 Or else it means that the *meter* is connected via cord, to the flash system. I think that's it. Still looking for the manual . . . Link to comment Share on other sites More sharing options...
Rob F. Posted October 5, 2003 Share Posted October 5, 2003 I found the mini-refeence card. It says, "Readings can be taken with or without the synchronizing cable. "_Select the (lightning bolt symbol) with the function buttons." But it doesn't say to select "COR" for use with a synchronizing cable. So I can't be sure that I told you right. I've got the full manual here someplace. I'll have to stop guessing and go look for it. Link to comment Share on other sites More sharing options...
gee-bug Posted October 5, 2003 Author Share Posted October 5, 2003 I read somewhere on the net that this meter can "learn" the exposure compensation value of a particular filter. I think the "COR" mode may be where this is done. Link to comment Share on other sites More sharing options...
dford Posted October 5, 2003 Share Posted October 5, 2003 When in the COR mode depressing the M establishes a ReFerence measurement. Place the filter in the path of the sensor and press the M button again. This measures the correction factor for the filter. The COR value will be used for all subsequent measuring functions. To clear COR value press M to display rf and then select any other function button. The box around the COR will disappear. Link to comment Share on other sites More sharing options...
gee-bug Posted October 6, 2003 Author Share Posted October 6, 2003 Thanks, Doug. This makes sense. Link to comment Share on other sites More sharing options...

nikolas Posted October 6, 2003 Share Posted October 6, 2003 In addition to what Doug said, when in COR mode, you can change the correction value manually using the value buttons (up/down arrow). The left-hand figure shows the correction value in stops and 1/10th stops. I understand that the right-hand value shows the extension factor, which is applicable for negative correction values in stops. Link to comment Share on other sites More sharing options...
melvin_bressler Posted October 6, 2003 Share Posted October 6, 2003 Ken: Find Gossen on the net and contact them. They are part of Bogen Photo. The will provide a PDF version of your meter's instruction book for down loading. I have the "Pro F" model, not digital, and the controls are different.
