As with the previous entry this was also taken in our local bus station. The image didn’t require much by way of post-processing other than some levels and curves adjustment, no change to the saturation, and some minimal sharpening. The only real change between this and the previous image is that I’ve removed the wide aluminium frame from around the image. I’d like to be able to say this was intentional but I only took a couple of shots of this poster and I cropped both a little too tightly; i.e. there wasn’t enough of the frame left in the original to include.

The sharpening technique I’m using at the moment involves converting the image to LAB colour and then using the following Unsharp Mask settings on the Lightness channel: Amount (160%), Radius (0.6 pixels), Threshold (8). This sharpens the monochrome channel of the image and, therefore, doesn’t affect the overall colour balance of the image, nor does it introduce any unwanted colour fringing.

When I posted the previous image I hadn’t looked at this one. What’s much more noticeable in this image is the distortion to the reflections. I guess I’d assumed that these posters were covered with glass but, having worked with this image, I would suspect that it’s perspex of some sort, hence the distortions (particularly noticeable in this image down the left edge; i.e. the reflection of the bus).
