Midjourney V7 updates: Omni Ref, EXP & Q4 Parameters

Using 3D printed images of the 1936 Flash Gordon rocket ship as my Object in the Omni Ref, I explore some of the latest updates to Midjourney V7.

I found these cool 3D printed images of the Dr. Hans Zarkov’s homemade rocket ship from the 1936 Flash Gordon series, that takes Flash, Dale and Zarkov to planet Mongo on their first flight attempt. (1 year shy of 90 years ago!)

Using the first image:

Award winning Cinematic still frame from the 1936 Flash Gordon series, featuring Zarkov's homemade rocketship. The rocket is made of riveted shiny sheet metal. Industrial, somewhat crude appearance to reflect homemade. The rocket is a cylindrical, bullet-shaped vessel with a pointed nose cone and stabilizing fins at the rear. Background of deep space and the planet Mondo. --ar 16:9 --raw --profile ey96xs2 --oref https://s.mj.run/nb_G-6pLYKk --ow 75 --stylize 150 --v 7 --exp {0, 5, 10, 25, 50, 100}

Let me break this down just a bit. I am using the Omni Reference (using the 3D render) with an Omni Weight of just 75. I have applied a varied --exp showing the impact from 0 (none), 5, 10, 25, 50 and 100. The --exp parameter is a new, experimental image aesthetics parameter. What does it do? It is similar to the --stylize parameter, but it increases image detail, making the result more dynamic, creative and tone-mapped.

You will notice that as the exp value goes HIGHER, the prompt accuracy and image variety decreases.

—exp 0
--exp 5
--exp 10
--exp 25
--exp 50
--exp 100

A few of the above images were decent enough and sort of matched the original design sample that I uploaded as an omni reference - but it is a bit hit or miss with my omni weight so low.
