Light box question

The ones that came with the cheap kit I bought on Ebay. Like $40 for 2 lights on tripods and the tent itself. I swapped the bulbs to a yellower light though because I didn't care for the harsh blue LED light they came with.

Ah 6500k. Mine came with 5000k and they're harsh.
 
Never mind. Misinformation and not explaining myself well.

Off topic but what type of wood is that kuraki? Sorry new to this and can't identify woods yet!

I have dealt with a lot of spectral and lighting science. The higher the kelvin temp equivalent, the brighter and more white. It is very yellow at 3000K, more evenly white at 5000K, and getting into daylight blue at 6500K. The range follows the spectrum from red at 1000K to blue at 8500K. If the light gets above 15,000K it enters ultra voilet.Below 600K it is in the infrared range. Ironically, we call the lower temperature range around 3000K warm, and the higher temperature range around 5500-6500K cool.

The higher and whiter, the more harsh on the eyes. That is why room lighting is 3500K and store lighting is 5500-6500K. Jewelry is always shown at 6500-8500K to briing out purer colors of gemstones, and add refractive colors of diamonds.
 
Oh. Then I stepped back down to 3500k range with halogen bulbs.

Buckeye burl with some resin casting.
 
some advice on the lighting an expert gave me,
play around with the distance of the lighting around the box, that will have an impact
 
Thanks guys, time to start experimenting with lights, if they don't work for the light box I can always use them in my dim shop.
 
I don't think there is one answer. I have had to try several different bulbs and use a grey card and a hand held light to take out shadows and glare spots. If you don't have all the lights and light box then photograph your knives outside on an interesting background just before dark and use no flash. Getting great knife pictures is some real "trial and error" work unless you been professionally trained at a photography school. High polish knives are especially difficult because they show every reflection and glare spots. I do not have any perfect photographs but I share them anyway. Don't give up. Larry

Larry is right about polished blades. Capturing hamon well it's next to impossible too.
 
don't forget it's simple and easy to play with digital settings of the pic even from your smartphone
you get to adjust exposure, brilliance, brightness etc etc.
 
Experiment a bit. At least in the past white LEDs started with blue with a coating ! Colors used in backgrounds can change things too.

Man, I like diving into rabbit holes more than most, but if I can't take our 40D and spin the wheel to auto and get the level of quality I can be satisfied with because I set up the physical environment, I'm not going to do it. I would rather manually parse a 1,000 lines of G-Code looking for an erroneous decimal point on a computer with a cracked screen sitting on a table with one short leg while the dog humps my leg and someone in the same room plays youtube videos of babies crying than spend even one second contemplating what ISO means. It literally makes me want to smash my head on the wall.
