Hi. I am not good at taking pictures.
But I take pictures of extremely small insects to publish a scientific article.
A few days ago, I set new pieces of equipment.
Canon 90D + Canon 70-200mm + Mitutoyo 10x, 50x, 100x
I tried to use new ones.
However, when I took a picture using two strobo flashes with a camera flash, it was too dark even more than using the camera's flash only.
So I tried to use only one strobo in 1/128, then it worked. but when I tried with 1/16, it was darker than the latter.
How could this happen?
p.s. I used Manual mode. So It would not be from camera mode.
Please answer me

That is a puzzle! But here is a discussion about a similar problem, and maybe your answer is in here:

I read some posts in the link.
I figured out what was the problem.
I had no idea about TTL mode. In this mode, the flash fires twice very quickly. so, the strobes don't have enough time to recharge.
I turned off TTL mode, and it is fixed.
Thank you.

Good catch! That was a tricky problem, and I wondered what the solution would turn out to be.
