Temp of color using two strobe's z-240 in a Nikon D80

Recommended Posts

Hello

i am using a external converter for TTL (HeinrichsWeikamp), i have a Nikon D80 camera and i am using two strobe's Inon Z-240, and when i start to use the second one, my photos have a "strange"color.

i'd like to know, in the white balance, what temperature should i put?

 

thank you

Hi Bernardo,

 

What type of strange colour do you get?

 

I have the same setup. I can however not say that I get strange colours when I add the 2nd Strobe.

I just let the Camera do the "Auto" WB and then I correct it in Capture NX if needed. That works fine for me.

 

A rather elegant solution would be to have Grey fins, that can be photographed everynow and be used as a Greyscale.

5500-5600K is a good starting point for Inons. Alex

 

Hello Alex,

 

that was my start, and when i was using one strob that works just fine, but know i have more dificulties to understand the color in the photo

 

this photo is with one flash

and that one is with two

thank you

The second images do seem to have some issues. Not sure that it is all down to white balance, though.

 

How does the camera perform shooting them same subjects (single and dual strobe) on land?

i never tried on land to shoot with one, only

 

i tried with two and the results are not conclusive, i tried in some flowers in my garden, but the light conditions are diferent

i shoot always in manual, iso=100, wb= 5600ºK.

 

i dont realy understand what is happening...

I am also not really sure what the issue is. In the 4th Pic, 5739, the right hand flash is perhaps a bit stronger than the left hand. The distance seems short enough for TTL to work in all 4 cases.

 

I would take land pictures of the same topic with 1 resp. 2 Strobes and compare them, just as Alex suggests.

Hello again

o forget to tell that one oh the strobes is type II and the other one is type III, but i do not think that can cause the diference.

 

if i shoot to close of the subject, wiht two strobe's, the TTL do not work (+/- 5cm) in land. Underwater it work's perfect (but the color is not god as i told before)

 

the arms have 30 cm long

 

i shoot wiht a lense nikon 18-55mm and a 105mm and use a barbolight 04 as a focus light

I can not really imagine that type II or III makes a big difference, for this issue. Mine are both of Type II.

 

Hmm, I was just having a look at the Pic 5632. It might be a stupid idea, but are you sure that the Strobes fired?

Not such a stupid idea Erik.

When I first looked at the second photo in each sequence I thought the same thing.

None of the colors are showing strobe influence at all. . . . IMHO

Seems to me that by adding the second strobe you are losing contrast. To me, on my monitor, uncalibrated iMac, the colors look fine. But, by adding the second strobe you lose the depth and shadowing. If perhaps you could turn one of the strobes down by a couple of stops.

 

I use the S&S TTL III with dual YS-110's and have the same problems as you. It is a problem I'm trying to overcome as well, and it happens when I pull back from my macro shots on the same subject and on CFWA shots if I'm too far away to make the TTL effective.

Hello Erik

it's not a stupid idea, but i use both in TTL so i think both fired, could be bad oriented??

 

this photo was shot F/10, and 1/100. it was a night dive, maybe i shoud use F/>10?

Hello Bruce

 

is it possible config camera settings to change that? or could be because bad orientation of the strob's?

Hello IMSushi

 

i do not know if it possible turn one of the strobes down a cuople of stops, because, as i said, both are connected to the external converter.

your connection is electrical or optical?

Looks like the second image is not lit? Perhaps your strobes don't synchronize to the camera properly? Do you have the 'adv. curcuit'-button on the Z-240:s pushed in?

Hello Christian,

yes i do, because if i does not have it pushed, the z-240 does not work wiht the Nikon D80.

as soon as i get home, i am going to try to shot wiht one and then wiht two strobes, as Alex said...

and then i will show the pics...

 

i have try every thing i know, because i do not understand what can happened...

 

that's why i put the question is this forum...

Hi again Bernardo,

 

Bruce: Thanks

 

You can actually limit the max allowed Strobe dump, by having the advanced cancel circuit pushed in and switching from STTL to M -0,5 to -6. It is supposed to be for Film Cameras with TTL, but it seems to work.

 

Back to the Pic 5632. If it was a night dive F10, 1/100s and assumed ISO100. Then Contrast seems too low for a strobe hitting it. What was actually your ISO Setting?

Then it should "just" be to get it working in that wet element as well.

 

I would expect the normal "suspects":

* pointing the Strobes correctly,

* not waiting long enough for the Strobe to recharge &

* the "advanced cancel circuit" button not pushed in etc.

 

Been there, done that and still happens :lol:

Hello Erik

 

i hope so,

but underwater, in portugal, the water is dark green, and increases the dificulties, the viz is +/- 5mts at the places i use to dive...

i am going to Malasya by the end of this month, and i am trying to have everything ready, including all this questions...

 

thank you all
