Yes
can you mix flashgun and stuido lights together or do mess things up
 
As long as both are around the same colour temp then it will be fine

Ive never had a problem with Sigma Flash units, should be same as studio flash.

Biggest problem is mixed lighting ie Daylight/Tungsten or Flash/Tungsen in which case you'd have to gel up a specific lighting source or use a filter on the lens for one or other source
 
Yes, you can mix them - but variable colour temperature can be a real issue with hotshoe flashes so you may need to experiment, find a power setting at which it more or less matches your studio lights and use it at that setting
 
thanks guys
i have one 150ex (5700k i think) shoot throu umbrella and sigma 500d super ?home made defuser
camera wb set to 5700 k
 
I mix my Canon speedlight and Elinchrom d-lites together fine. Although I usually only use the speedlight to over-expose white background when necessary....
 
kool i was gonna use it for hair light,
but plan getting another flashgun too
 
i have my cam set "k" 5700 cos the interfit are 5700 is that correct ???

Yes, correct - in theory.
But no flash units ever actually produce the colour temperature they claim. Bron is, in my experience, the best by far. Typically a difference of around 40K from max to min power, which is ideal but very expensive to produce. They achieve this by having a very large number of capacitors, wired in parallel. Basically reducing the power involves switching out capacitors, this reduces the power without reducing the voltage, this is important because reduced voltage dramatically increases the duration of the flash, which in turn reduces the colour temperature.

Cheaper makes tend to economise on both the number of capacitors and the circuitry, this means that the colour temperature (and the power output) varies quite a lot from one pop to the next, and also changes dramatically when the power is reduced.

As with most things, you get what you pay for - so the cheaper the flash, the less likely it is to produce accurate and consistent colour temperature and/or accurate and consistent output consistency. See this brief article on how you can test colour temperature for yourself.
 
thank you for that gary ,i ll have a read,
bigist prob is brown hair looking red ,not sure if its light,or cam setting

Well, if those figures are accurate you have nothing to worry about.

as best i could, naked light follows your test,so yeah fairly accurate i say,
there is a deferecne from dpp and cs3




so next would be camera setup
 
Hi If the browns are red, it may be worth trying a reduction in the lights/flash illuminating the hair, as it may be related to an over exposure on the hair. (Not sure though, just a thought).
 
think its more to do with either not enough/or light spreading around

subject, or white balance setting,ive just stuck some new photo in people section
