Happy accidents. Serendipity. The silver lining on a dark cloud. Whatever you call it, its the moment when something goes horribly wrong but eventually ends up being really, really right. These moments are everywhere in art and photography. Back in the days of film, there were countless mistakes in processing and exposure that creative types turned from tragedy into triumphant special effect. A leading contender in the photographic happy accident category? Reticulation.
Film reticulation is caused by shrinking of the gelatin emulsion during processing. It creates a blotchy, grainy, spotted-looking photograph. Its usually due to a dramatic change in temperature during developingmoving from a very hot wash to a very cold wash, for example. The first time it happened, the photographer was probably upset. But maybe he looked at the photo a little more closely and decided it looked pretty cool. Now that were not processing much film in chemistry anymore, are the days of happy accidents behind us? I hope not. Even if actual film reticulation has gone the way of the dinosaur, the look of this happy accident can still be created in the computer.
To funk up your pictures with faux reticulation, look to Photoshops Reticulation filter. Dont let the name fool you, though: sure you
could run it straight and get a good effect, but by combining the
filter with some other powerful features like layers and layer
properties you can make the look as dramatic or subtle as youd like.
Start with any old shot youd like. You can convert it to black-and-white before you begin, since the most common reticulation effect was
seen in home B&W film processing, but theres no rule that says you
cant do it to color photos too. (If you do choose to reticulate a
color photo, consider desaturating it a bit before you begin. Bold
colors can certainly work well, but a little faded, antiqued appearance
often lends itself to the added texture of the reticulation.)
Regardless, if you ran the filter alone, it would convert the shot to
black-and-white automatically.
Duplicate your photo onto a new layer; this will become the
reticulation layer. In the Reticulation dialog box (found under
Filter > Sketch > Reticulation), adjust the density slider for more or
less distribution of those reticulated dots throughout the frame. For a
subtle look, go for a higher density number; a lower number means a more
reticulated, harder-to-read, photograph.
The foreground level and background level sliders, for all practical
purposes, adjust the brightness of the scene. Foreground means the
black reticulated dots, and a higher number here means larger dots,
more connections, and ultimately a darker overall look. Background
represents the lighter area behind the dots, so a larger figure here
means less reticulation in highlights, and greater blooming of the
scene highlights into other detailed parts of the shot. Strike a
pleasing balance between drama and detail. Keep in mind, too, that
well be adjusting this reticulation additionally in the next step, so
a slightly heavy hand isnt a bad idea.
Back in the layers menu, turn your totally reticulated image into a
shot that balances nicely between useful detail and special effect. To
do this, select the reticulated layer and, in the layer properties
drop-down menu, set the layer to Overlay. This makes the overall shot a
bit more contrasty, but it allows the original color and detail to show
through, adding the darkest reticulated parts to the scene without
obliterating everything in its path.
Adjust the layer opacity to fine-tune the amount of reticulation and
detail in the image. To further fine-tune the detail, work with a layer
mask or simple eraser. With the mask, just paint (at a low opacity and
soft brush) on the layer in areas where you want more detail to show
through. Continue building the mask until youve put back all the
detail where you want it. With an eraser, the same process
appliesremoving reticulated density to reveal the original image on
the layer below.
For a last little tweak, consider adjusting the sharpness of the
reticulated layer. This added definition to the reticulated edges can
provide just the kick this newly softer shot may need. I like Smart
Sharpen, but even functions like Find Edges and Threshold can give the
reticulation a further funky feel.
Just as with the original film process, theres no textbook way to
reticulate your photos. But thats the great part, too. Just as with film, some of the fun is the experimentation.
