lightbulbs....
lightbulbs that are labled "soft or warm" white are going to be yellowish in tint they are designed to feel like old fashioned incandesents and candlelight they are the MOST common type on the shelves in the fluorescent section they are low on the Kelvin (measures the color-temperature of the light) spectrum (about 3000).
lightbulbs that are labled "sunlight or natural light or daylight" are going to be more pure white with a hint of blue and will seem harsh if you are used to the yellowy ones. they are much higher on the Kelvins (4000 to 6000)
the "reveal" lightbulbs by GE are VERY blue and are designed to make plant folliage look healthier and not wilty. they are actually coated with a blue film. not recomended for photo takeing unless you are going for an underwater or icy feeling
for photo takeing I use the fluorescent daylight bulbs in higher "wattages" 75 to 100 equivalants (1200 to1700 lumens) in multiple locations and one 40watt equiv (500 lumens). bulb in soft white to kinda balance the harsher shadows
for everyday living I have slowly been changeing all my bulbs to the daylight kind....somehow my kitchen doesnt seem as dingy, dirty anymore...after all that scrubbing and bleaching and curseing it was the LIGHTBULBS....grrrrr
my bedroom still has one warm bulb in the ceiling. it looks really sickly orange compared to the daylight bulbs which look white.
my nerdy knowledge comes from working in the hardware department for a year. lol
