In Lightroom and Bridge (comes free with Photoshop) this Exif data is easy to find, the default program settings reveal this information clearly.  Not so in Photoshop where it is buried under the file menu (in Windows).

File — File info.… reveals the Exif data for any image you are working on in Photoshop. Click on the Camera Data tab to see the exposure information.

The keyboard short cut (Windows) ALT + SHIFT + CTRL +I does the same thing.
The keyboard short cut (Mac) OPTION + SHIFT + COMMAND +I does the same thing.

But if this is not possible, Photoshop can help you achieve that ‘near perfect’ shoe shot by extracting it from the background. Photoshop’s selection tools work well to get the job done. The quick selection tool is great for simple extractions. The background eraser is another great tool. Although many people loved the extract tool in Photoshop CS3, it’s missing from CS4. (If you loved it and still have CS3, you can copy it from the CS3 Plug-ins-Filters folder to CS4).‚ But depending on the subject, these tools may miss out on some of the finer details like a model with frizzy hair. In cases like these, manually tracing the edges with the pen tool and then converting it to a selection is ideal. Tedious yes, but it will give you optimal results.

Pluggins are also available for removing backgrounds if you’re up for the expense.
Who knew shoes could be so technical?!

Photoshop provides numerous methods to master the vignette. Want some insight? You can use an elliptical marquee tool, inverse the selection, and blur the four corners. You can also brighten or darken the four corners by working with the level balance on the inversed selection. Lens correction (Filter ‚” Distort) also works well for adding a vignette. These are only two methods, but there are certainly more.

But what about those who prefer working in a darkroom to achieve their artistic photo effects? In the darkroom, this is done by holding an opaque material with a circle or oval cut-out during the exposure.

Either way, a vignette can add drama or even soften a photograph all at once. The possibilities are endless.
