Photo-editing help

[PlutonianEmpire]

Recently, I've been trying to superimpose a Celestia screenshot of Delta Trianguli onto a photo I took of a sunset, but the only problem is, I'm unsure as to how to reflect the two magnitude difference in brightness between the two suns, as percieved by the human eye.

All I've been able to come up with was this:



I honestly don't know what luminosities of 0.178 suns versus 1.12 suns should look like to the naked eye, or even a digital camera.

Some help/feedback would be appreciated.

(And it may seem otherwise, but I did not erase any tree parts to put in the second sun. )

EDIT: Here's a more user-friendly image.

The distance from both suns for this photo-edit is supposed to be about 1 AU, the Earth's distance from Sol, and the Celestia screenshot I used showed the two suns at maximum apparent separation. The suns' distances from each other is 0.11 AU.

(For Belle Hades, the distance from the suns would be 1.14 AU)

So this might be somewhat more reasonable photo-edit, or not even that?

The Sun's image is saturated, though, isn't it? So it isn't obvious to me how much dimmer the other sun would be, especially since it's higher in the sky with less atmosphere to cause it to be less bright.

It's not obvious to me either, which is why I posted this thread.

What is the temperature of the small sun?

What is the temperature of the small sun?

4,590 Kelvin, in Celestia.

The big sun is 6,030 Kelvin.

Imho, at noon the small sun should be more bright. At sunset the small sun should be dark orange-red and the big sun light yellow.

EDIT LATER:
Another useful parameter about the atmospheric issues should be the min. and max. angular separation amongst them, if any.

I was wandering about the - possibly - rainbows' intersection and its behavior on colors. Another could be the diffraction's issues concerning the atmosphere when the suns are - possibly - closer.

I would saturate both suns. If they're both about the same brightness in the screenshot, then they should be about the same in the photo.
