[quote=“Ray Meketa”]I took that quicky eye test and passed with flying colors (pun intended). As my eye doctor told me at my last checkup, “You’re eyes are fine but you have a bad case of O-L-D.”
I was going to ask about using a blue light bulb instead of a white. Back when cameras used film, indoor photos were shot using a special blue bulb that somehow enhanced the colors. I’m not sure how it worked but was wondering if possibly this would be an answer? I’m not talking about a standard blue bulb but a special one made just for photography.
Anybody know about this? Maybe this is what EOD was talking about?
Or should I simply get a gizmo like Gourd suggested with LED light? Or an LED flashlight?
Ray the reason for the blue bulbs was that outdoor film was built / balanced to record true color at 5200 degrees Kelvin. (a light color degree measurement standardised as the overhead sun on a cloudless day) The colour of an light bulb in a lamp was often about 2800 to 3200 Kelvin which was/ is quite yellow, so the blue bulb brought the light back to 5200 & the film recorded the correct color.
There was an indoor film made but it was not in common useage for most photographers, unless they did a lot of work photographing interiors with lamps normally in the scene, such as Better Homes & Gardens & etc. Although some photographers did substitue a flash bulb for the conventional light bulb to get correct color light but it was hard to do because when the light was tuned on the flash went off! Also good way to have fun? with your friends!
Thats the deal with flim response, nothing to do with seeing / judging color.
I should also add the same color shift is true with digital cameras
With out changing your set at daylight white light balance (if your digital has such a control) take a photo outside then walk inside and with the living room lamps on and with the flash off take another photo, and you will see a yellow cast to everything, put your flash on (it is balanced to daylight 5200 K.) & the room colors will appear true but look closely at the areas around the lamps and you will still see the yellow cast.
clear as mud? Well I should hope!
