Every couple of years or so I visit the Bedfordshire (UK) Steam Fair and take tons of photos. This time I kept it down to just over two hundred; amazing self-restraint! I concentrated on unusual angles, detailed close-ups, and the like. This is part of the works of a paraffin (kerosene) fuelled vintage tractor. I cranked up the saturation a little in the first image, and later I thought I'd try it in mono. For that, I desaturated it and put it through the HDR persona to increase the local contrast, as well as the overall contrast. (Sometimes I find a better B&W result can be got by turning down one or more of the colours in the Black and White adjustment, but I didn't need to in this instance.) And if you're wondering where this lot fits on a tractor, here's the whole thing ... (If you want to see the other 217 photos, let me know!)

What I would really like to see is a new shape to create involute gears, which are one of the most common types. The Cog shape doesn't work because involute gears have rounded sides to the teeth. Maybe contact or pressure angle could be added to Cog. The pitch diameter would also have to be specifiable or indicated as this would be different from the outside diameter controlled by Transform.
