Hi,

I am in really need of some help. I just bought the big octa, 1.9 big octa and I was testing it last night.
I ordered the adapter for profoto so I can use my monolights with the big octa.

Put it together is a breeze, it is so big but so easy to assemble. When I installed the diffuser and turn on the light, I notice a dark spot in the center. I have seen many pictures and videos for the big octa, but I have never seen this before. I know the dark spot is the back of the light blocking the light.

I tried with multiple settings and it is a constant 1 stop difference from any point from the big octa compared to the small dark center. I can work around that, placing the model in different places, but It is a way to avoid this dark spot. Fix this?

Any thoughts.

I saw a youtube demo about the big octa and the guy is using elicnchrom 600 Rx http://www.youtube.com​/watch?v=6yp9dzzZiM0 (external link), if you have this head, could you tell me the dimensions so I can compare with the profoto head. I am thinking the profoto is longer and casting the shadow.

Help!!! The big octa gives an amazing light and it is easy to work with. It just need to let your imagination fly and it is magic, but it has a center dark spot :-(

I have this modifier and its GREAT!

I use it as a background some times. There is a dark spot. I have not measured it but I dont know if it is a full stop different. It really doest bother me because it doest affect my image that I can see. Even when its the BG its not noticeable


Don't try to confuse me with the facts, my mind is already made up.

i don't have a profoto D1 to try out on my octabank but just looking at the design of that strobe it apppears to me that it is more directional and probably not filling the whole octabank with light

my 600RX fills the whole octabank so much so there is wrap around the strobe leaving no dark spot in the center, i get the same meter reading in the center as i do on the edges

Changing the D1 to the optional dome instead of the stock flat glass cover over the flashtube will give you even light in the Octabank.

Just to keep it updated this post. I got some answers in another forum.
The ring adapter for profoto has a small reflector that prevents the D1 head to go deep into the speedring. I guess that and the D1 design is making the dark spot.
They suggest to remove this reflector, I did this morning and it indeed the head slide further this time. I now can use the dome with the head.
That is the same advise that I got from Elinchrom Europe, so I think I am in the right track.
I will test tonight when I get home.

I will keep posted.

Yes, it is almost even. The D1 are larger so I have 2/10 difference in the center. The difference is the black center is a lot smaller and it is just 2/10 of stop.
