Keep reading about AB color inconsistancies.
And not just that particular brand there are others that supposed have this problem but I still want some AB400s to haul around and not worry about . There seems to be only 2 brands that people say dont have this. So on the ones that do have inconsistancies , how bad is it ? Is it less noticible using light modifiers? What is the fix for it in photoshop? Anyone have a example of how this would look ? Is it usually just in one or two shots out of a hundred or is it more random and unknown? Are there chances of getting ABs that dont have this problem and its more related to a particular lot that was made? Jul 10 08 01:19 am Link I have 1600s and 800s, the shift is an easy adjustment in camera raw. edit: I see it less in the 1600s then the 800s Jul 10 08 01:23 am Link I use a meter and set my WB for sunlight, what do you set yours too? Jul 10 08 01:26 am Link custom white balance makes this a non-issue Jul 10 08 01:27 am Link 1600's here and I haven't actually noticed it. Mine seems pretty consistent from start to finish. But then my sets/looks tend to be pretty quick so it's possible the lights are cooling down before they start to shift color on me.

If you are not shooting commercial where color matching is critical it probably does not matter at all. They say the same thing is true with the White Lightnings but I am perfectly happy with mine.

(for 2 years) I find the lights very consistent per shoot, but twice now I had a bluish cast on everything. Jul 10 08 01:35 am Link Corwin Prescott wrote: makes it more apparent, in that you set to one and it shifts from it, some shots are very accurate, some are not, which is correct? Of course only matters if you want accurate to begin with, or at least want consistent all the same off factor Jul 10 08 01:39 am Link Try to measure the color inconsistency of almost any flash unit... you'll likely find you have better things to do with your time. The ABs exhibit some inconsistency at the low end of their power scale, so turn it up and move it back.

I thought the color shift was a fluke until I started reading about it here. But thanks!! that is something I will try next time - lower power setting. I would love to know the reason behind this!!

Also, remember that the more light you have, the less color is apparent. Put a gel on your light at full power then try that same gel at low power. Jul 10 08 01:43 am Link PhotoDancer wrote: It's true with nearly all strobes. Color temp varies by a few 100 degrees from highest to lowest settings getting red-er at the low end. For individual light, not an issue. Worst case is if you have 2 lights, one on min, the other on max. Jul 10 08 01:44 am Link If the shift is apparent at low power settings, instead of turning up and moving back like said above, it may be more beneficial to add an ND gel to your modifier so you can still control the quality of light while cutting a stop or however much.

But I can see if you have time constrants and want to do batch conversion it could be an issue . Jul 10 08 02:34 am Link |
