From my 22nd photo shoot I went with a different technique through experimenting with exaggerating the inherent contrast in the motive:Though the edit is simple, the preconditions here are essential. Down bellow I’ve made an attempt at analysing how one could replicate the effect.
The first precondition which I think is the most essential is the values of colour in your image. Bringing up the histogram you can compare your values to mine to the original vs the grainy version. While I won’t (and can’t) get too technical, there are a few prominent characteristics :
- “Suspension bridge shape”
- The RGB values (Red, Green and Blue) are similar making for quite a flat image
- Quite a lot of grays
You can get this particular window by following the short video bellow. (A lot of other photography applications/programs include this, even the simpler ones including apps). You can preview the video if you right-click it and select “open in another tab”.
So with these three key elements in place lets look at the contrast curve I set for the image. Using the curve tool in Photoshop I am able to manipulate the levels of which colours that will be expressed in the image.
The video bellow illustrates the effect (Filter-pixelate-mezzotint-whatever type you would like) I have added to the image to effectively removed certain colours from the image adding more gray.
So analysing the curves side by side we can see that I have moderated the values to the left while exaggerating the levels on the right of the spectre That makes for the gradient look. A video bellow illustrates this perfectly. The curves in the curve tool is similar to the curves of the original photo. I am not entirely sure what that makes for but I believe by having a curve similar to the shape of the histogram, you to a higher degree preserve the colours in the original photo.
Actually “Inverting” the curve makes for this result:
