steve_frens Posted March 1, 2008 Share Posted March 1, 2008 Hi, Does anyone have experience with lux meters - for example, like the ones offeredon ebay for low prices? Seems hard to find good reviews about them on theinternet. The ones I'm looking at go from .1 to 100,000 lux. I have found somegood info about converting lux values to the ev scale. This is what the auctionsays, but is it believable? "This lux meter features an extremely precise accuracy (?4% rdg) through0.1-100,000 Lux readings in four ranges...Photo, and Film Enthusiasts have ratedthis as the HIGHEST QUALITY and BEST SELLING Lux Meter on eBay." I work mainly using the sunny f16 rule with pinhole and an old minolta srt witha broken meter. The info from this site, http://www.fredparker.com/ultexp1.htmhas helped me a lot with estimating exposure values but I think a meter woulddefinitely improve things. The lux meter seems like a good option as it'saffordable. A .1 to 100,000 lux meter can meter on the EV scale from roughly EV-4 or 5 to EV 15, which is good enough for me. But again the question is, hasanyone used these kinds of meters with success? I suppose they just read ambientlight and not reflected light which is ok with me for now. Thanks for any input, Steve Link to comment Share on other sites More sharing options...
craig_shearman1 Posted March 2, 2008 Share Posted March 2, 2008 Can't tell much from the photo, but if this meter reads out only in lux you don't want it. Lux is a measurement of light intensity (I believe one lux and one lumen are the same but double check that.). All meters read lux. But rather than giving you a reading in lux, they usually translate it into an exposure setting of a given f-stop and shutter speed for a given ISO. If they only gave you the lux reading and you had to go look up in a chart what that translates into for exposure, that would be a step of about 50 years backward in the way that exposure meters work. Not sure, but a lux/lumen/footcandle meter might be used in some cinematography applications, but not generally in still photography. If you want a meter, get a standard meter. Sekonic is probably the most popular brand. Link to comment Share on other sites More sharing options...
