Exposure is a plug-in for Photoshop and Paint Shop Pro that claims to be the closest thing to film since film. Peter Bargh checks it out to see if he can re-live his wonderful days with the likes of Kodak Tri-X.

Exposure is from Alien Skin, the people behind such great plug-ins as Eye Candy, Xenofex and Splat. Unlike the previous software, where strange effects could be created, this is for the more serious photographer and offers more serious results.

The idea is simple - a set of controls that let you adjust grain, sharpness, colour and saturation in the highlights, midtone and shadow areas. Doing so allows you to create the subtle differences that you would have found when exposing and processing a conventional roll of film.

You could do most of the things you can here with the controls available to you in programs such as Paint Shop Pro or Photoshop, but not with the ease or clarity that Exposure allows. The program is so simple to use, and what makes it even more foolproof in mimicking your favourite film is that a series of presets have already been worked out for you. These include black & white films such as Kodak T-Max, Konica 750 Infrared and Fuji Neopan or colour films such as Kodachrome 25, Fuji Velvia 100 and Agfa RSX II.

Installation couldn't be easier. The program comes in a plastic VHS video sized case, I'm not sure why they couldn't stick it in the more convenient DVD sized case, but that's no real gripe. The instructions provided include a few bits of basic technical data about grain structure etc to help you understand how the program works along with very helpful sections on each of the manual effects tabs. The developers actually put films under the microscope to help create the engine for this program, so it's not just based on pixel pushing, but on real film!

In use
When loading the CD, the existing image editing program's plug in folder is automatically found and everything slots into place with no effort. Restart Photoshop or Paint Shop Pro and the plug in appears in the filter menu.

Now when you open a photo you can select the Alien Skin Exposure filter and go straight to the Color (It's an American company!) or black & white film presets lists.

Below are a few of the controls and a short explanation of what they do. Click on each photo to view a higher resolution version to see the palette clearly.

First tab is the settings menu. It's here where you can select one of the many pre-created film types. Here's the black & white options. The filter menu lets you select Colour or B&W. The preview window can be split so you can see the before and after versions. Red indicates the after version. I've changed the split on the various screenshots. The preview can also be magnified using the Ctrl and +/- keys and moved around using the hand tool.	Each film type can be selected and then modified using the various tabs. Here I selected Kodachrome 25 which shows an increase in saturation on the red and blue channels in the colour tab. By playing around with these controls you can emulate more or less any emulsion going, providing you have a good eye for colour.	The tone tab gives you control of contrast in the photograph. It acts like Photoshop's Curves but makes it easier to understand as you are in control of adjusting tone in the Shadow, Midtone and Highlight areas. When you adjust any of the sliders the palette shows the corresponding curve adjustment. I selected a cross processing effect from the colour menu for this example pic.
There are a couple of soft focus film effects to choose from and then you can click on the Focus tab and adjust the sharpness or blur (softness) to taste.	Here I first selected Kodak Tri X preset and then adjusted the grain. You have control of grain in Shadow, Midtone and Highlight areas and while playing I stumbled across really good lith printing effects which, when applied with a suitable tone, are very realistic.
Some of the film types appear true to life, although a few do go over the top. I never remember Agfa RSX II looking so red, although I do like the effect and it can be toned down using the colour tab. Also the box says you can recreate discontinued films such as Velvia...so where's Velvia 50???	From memory Ilford SFX gives a very life-like conversion, almost how it would look when exposed with a Red x8 filter. Sadly Kodak HIE looked way off the real thing.

The preview is almost instant and the processing is quick, unlike some plug-ins I've tried. One thing that is frustrating is the magnifier always defaults to high and top left corner, so when you change film you have to reset the image in the preview window to a preferred size using the Ctrl and - key. I thought there would be an option to change the default and looked up the preferrences...the only option here is to set the duration that the program checks for updates, some preferences!

Some of the preset effects I liked

Original	Blue Toning - Full tone	Selenium - Split Warm Cool
FSA red bleach	Soften - Glamour shot	Sepia - Mid Band Split Toning
Kodak Tri-X Pushed 1 stop

Verdict
This is a very easy to use plug-in that's fast and has some realistic emulations of some classic film and processing styles. The editing is easy to follow and the creative options are fantastic. I'm sure there are many freebie plug-ins/actions to be found around the world that do parts of what this does, but the hassle of trying to find them may not be worth the effort. $199 is steep for a plug-in but the time saved creating the effects makes it worth while, especially if you're a fan of old processes and certain films. It's a winner in my book.

In summary the positive points of Alien Skin Exposure are:
Very easy to use
Realistic results

The negative points:
Magnifier defaults back to top left
Expensive for a plug in
No Velvia 50!

Manufacturer's feedback
Alien Skin have read this review and have the following comments to add:

"Saving zoom and thumbnail position – Good idea. We’ll probably add an option to reset or use last position/zoom setting.

"Another feature to highlight – There is a before/after toggle for the preview pane, located top left above the preview window. Some folks like the split screen preview, but it can be turned off completely if desired. The before/after toggle is always available.

"Inaccurate and missing film types – No, we’re not going to get them all just right, but our preset system is infinitely expandable. It’s also easy to tweak the factory settings and resave them as your own. In addition, it’s very easy to import, export, and email Exposure settings as attachments. The manual, available free from alienskin.com, describes this in detail:

"Importing new settings is idiot simple. Just double click the new settings, like the ones on our message board, and they’re routed to correct folder on your hard drive.

"Price – True, $199 is expensive for a plug-in, but Exposure is for professional photographers who spend thousands of dollars on a new SLR and hundreds on lenses. For existing Alien Skin customers, we offer $99 upgrades for registered users of any other Alien Skin product. There’s also educational pricing available to students and teachers."
