<p>Okay, this is going to sound queer. But here's a phenomenon I came across several times now, and I do not know how to explain it - perhaps one of you can help?<br>
I do product photography for an online clothes store, and generally the work is easy enough. However, some colours - mainly red-tinted purple, but also some fluorescent yellow and vibrant pink - just <em>won't be photographed</em> the way they look to the eye. The purple just looks a lot more blue than ruby, and the yellow and pink look deep and saturated and loose their fluorescence. <br /> No matter how I fiddle with the white-balance (custom) or exposure or what way I turn the polarizing filter I shoot with, those colours never look the same in real and on the photograph. It isn't just a slight difference, either, but they look two completely different colours.<br>
It's not a problem to adjust the colours in Lightroom later to fit the original. But <strong>I would like to know how the discrepance ever comes to be, what could be the cause and how to eliminate it.</strong> It would safe me some time post-processing, and also, that's one of the most fascinating phenomena in photography I've come across to date. It's a complete mystery to me.<br>
I found some information on <a href="../photo/edscott/spectsel.htm#01">Spectral Selectivity</a> here on photo.net, and I thought it might have to do with the way certain colours are processed in the eye that the camera cannot imitate. But surely someone would have thought of a work around by now?<br>
Equipment used:<br /> Nikon D200 with kit lense <br /> Polarizing filter <br /> White carton backdrop<br /> 2x 300W flash with umbrella (for the main subject) <br /> 2x 600W flash with umbrella (for the background and sometimes backlight)<br>
I'd be thankful for any information or educated guesses.</p>
