Light Meter Question

[Alexander McCarron]

Hi,

 

I have a question about a newly purchased Sekonic Studio Deluxe III L-398A light meter:

 

I'm really confused by the lumigrid (the attachment for reflected light). I just pointed the meter at my light table with the lumigrid and got a reading of 160 footcandles. I put in the lumidisc (incident attachment) and got a reading of 450 footcandles from the same poisition (a little above the surface of the table).

 

So it would seem that I would need to stop down more to photograph an object illuminated by the light table rather than if I pointed the camera at the light table itself. What's going on here?

 

Thanks,

Alex

I'm also wondering how sensitive this thing is.

 

With the high slide out it doesn't seem to give much of a crap whether if something is just kinda dark or absolutely black.

I figured out the first question. I read that you need to do the reading for reflected light in the same way that you do a high slide reading and then immediately forgot about it.
