    Default Colour Temperature

    I am new to digital photography and want to get by with what I have if possible. I have a constant light source comprising 2x 400watt tungsten/ halogen lamps each with a colour temp of 3000K.They are R7S lamps. Does this mean that the colour temp is 6000K or still 3000K please ? I have already used them bouncing off an umbrella with very acceptable results ( by my beginners standards )
    Second question is will it be better to use a bounce technique or shoot through ?

    Doubling the number of units doesn't change the temperature...still 3000

    Can't really say which is better..it really depends on the quantity, quality, and the characteristic of the light you are going for. So, no real right or wrong

    Color temperature equals color of light. So if you bounce the light it picks up some of the color of the surface reflected off of. Same for shoot through except it picks even more of the objects color.

    I might also add changing voltage to lamp changes color temp. So normal power line variances change the color temp.

    Default Colour Temp

    Thanks for that Guys. I am now looking at changing the lamps but the only option I have for voltage change is to 110v from 240v.. However, LED lamps are a possibility and some are 5600K but the power of these is reduced . I am having to photo Ladies Fashions for my wife's business on-line. So the only pics I will need to take are clothes on a live but mostly dummy model. Can anyone please tell me what is the minimum wattage you think I need for this task in incandescent terms and the I can convert it to lumens.Only then can I decide which LED will do the job
