How To Simulate In Photoshop Orthochromatic Film On A Color Image

So, here is the layer stack that I used:

At the very bottom is the original colour image.

The next layer upward from that is a Black & White adjustment layer, one of PS's native tools. The settings I used are shown here:

The idea behind these settings is to simulate a B&W film that just has sensitivity in the bluish and a fleck of the cyan expanse of the spectrum. This blows out the sky, which is exactly what we want and is what is on "Layer i" of my layer stack.

To convert this to a simulation of a high contrast negative, duplicate this layer, hit cntrl-I to capsize it, and then employ image/adjustments/curves to farther increase the dissimilarity. The reason behind this last step is that for the purpose of this demo, we actually want to blacken the bluish sky and have almost no result on the other hues, so nosotros want these to come out very white on the simulated negative. The event is shown below (ie, the layer titled, "negative+curves" in the layer stack):

At this point, nosotros tin can simulate clamping the negative to the original. Nosotros do this by turning off all the layers between the fake negative, and changing its blending way to multiply.

I at present hitting cntrl-alt-shift-East to make a copy of the result on a new layer at the top of the stack. This is chosen, "Layer 2" in the layer stack, and is shown below:

This is the same as what I posted yesterday afternoon, and used most exactly the method I summarized in post #6 of this thread.

Patently, in that location are many possible ways to tweak this method to needs of any particular image, eg, where you want the sky slightly darkened, but not black.

I feel obliged to add that in that location are much more directly ways to become effects that are very similar to the above, simply the method I described to a higher place nearly exactly parallels the old schoolhouse moving-picture show steps, which is what you requested.

For case, one could simply select the sky (with whatsoever of several tools or methods), and apply a "levels" or "curves" transformation to just the sky. A quick & dirty version of this is shown below. Because this wasn't exactly what you lot were interested in, I did non spend any time accurately masking out the power lines, so they turned black along with the sky. However, on the plus side, the non-sky parts of the image are inverse less using this method. This might or might not be to your liking.

Finally, to be honest, I have never turned a heaven completely black before this. However, once I did, it occurred to me that this might be a quick way to become started with a day-to-nighttime transformation, e.k.

There is lots of fun to exist had with these methods.

HTH,
