> Me: If I want to blend 50% two images what should be the opacity of first image and opacity of second image?

> GPT: To blend two images equally—so that each contributes 50% to the final result—you should set the opacity of both images to 50% when layering them. The combined visual contribution of both images should total 100%.

It just keeps repeating this mistake no matter what I do. Btw correct answer is 100% opacity first and 50% opacity second. With 50%+50% the result is 75% opaque.

		Huh, mine corrects itself. Not sure what yours is up to If you want to blend two images equally (a 50/50 mix), then each image should contribute 50% opacity. Image 1 opacity: 50% Image 2 opacity: 50% That way, when composited, each pixel in the result is exactly halfway between the corresponding pixels of the two source images. One subtlety: If you simply stack one image over the other and lower the top layer’s opacity to 50%, you’ll effectively get 50% of the top image + 50% of the bottom image. But if you lower both to 50% and put them on separate layers without special blending, depending on the software, you might not actually get a true 50/50 blend — it could look faded. The cleanest way (in Photoshop, GIMP, etc.) is to keep one image at 100%, put the other above it at 50% opacity. That produces a proper 50/50 blend. Do you want me to walk through the math of why lowering both to 50% doesn’t give you a true 50/50?
