Re: measuring ambient spectrum (and eye one share)

Thanks for all the replies, some really useful information to follow up. With the encouragement of Dana, off list, I have got the unsupported power PC version running under Snow Leopard! It requires not just Rossetta but another crucial step which I missed out... Turn the computer off and on again after installing! (I know, I know! 101). Thanks also to José who replied off list with the link to Canon's Light Source Measure Tool, which I had not heard of. No graph as he pointed out, but still useful for ambient light measurement. http://software.canon-europe.com/software/0038349.asp I am away from the spectro at the moment, so will fully test all this with the device tomorrow. All the best, Rob.
