Modified Orton Effect
Since discovering the Orton Effect, I have realised that it doesn’t suit all images (thank goodness!). However, some images that I would have expected to look good, just didn’t, so I tried an experiment. Going on the principle that if you use a diffuser over the camera lens, the highlights spread, and if you use it under the enlarger lens when printing, the shadows spread, I decided to try inverting the tones before and after applying the Orton Effect. The results are quite interesting:
Original image
Normal Orton Effect applied
“Inverted” Orton Effect applied
With the classic Orton Effect, there is a certain muddiness, whereas the “inverted” version is more glowing. I will do some more work on this, but thought I’d publish this first trial just now.
EDIT: 5th June 2009
I have now settled on 4 versions of this effect, which follow these approximate stages. For anyone trying to follow Peter Hill’s method and relate it to mine, I only duplicate the layer once before blurring, blending etc. Unless you want to preserve the original background layer to check what’s going on, it’s a redundant step:
1:
duplicate layer – blend:screen – flatten
duplicate layer – gaussian blur – blend:multiply – flatten
2:
duplicate layer – gaussian blur – blend:screen – flatten
duplicate layer – blend:multiply – flatten
3:
negative image
duplicate layer – blend:screen – flatten
duplicate layer – gaussian blur – blend:multiply – flatten
negative image
4:
negative image
duplicate layer – gaussian blur – blend:screen – flatten
duplicate layer – blend:multiply – flatten
negative image
There are 2 essential differences between these methods: whether the highlights or the shadows are spread (blurred), and a difference in how the midtones are affected.
Here are the 4 effects compared:

If any of this doesn’t make sense, let me know :) Now, go forth and multiply (& blur & blend…)!

This is really interesting discovery. Thank you for adding this info to the group. I will have to do some work on it myself.

Agree with you entirely, Duncan !! It gives a whole new glow and quality to the images, somewhat like an oil painting, depending on the subject matter.

I must admit, I don’t yet understand why this works. Using diffusers to achieve soft focus, you are spreading light, hence the difference between its use at positive and negative stages (where the “light” in a negative is actually shadow). However, using software, you are just blurring the image, and there should be no bias towards highlight or shadow being more affected. Maybe after more playing around, I’ll have a better idea of what’s going on.

Actually, the penny has just dropped – we’re not simply diffusing an image; the two other steps involved (screen and multiply), combine to produce a (probably complex) non-linear effect on tones, so there is bound to be a difference between the 2 methods. Now I just need to measure what’s going on, quantify the effects and draw some curves, and then I’ll be happy :)

OK, after a bit more work…
Normal Orton Effect applied

Orton Effect applied, using inverted image

Orton Effect applied, using blur before Screen blend stage

So, by simply using the gaussian blur before the Screen blend step, instead of the Multiply step, we get a different effect. In this case, it’s similar to the method using an inverted image, but lighter overall. So now I have 3 Orton scripts in PSP – let’s see if it makes any great difference to the images to come :)
