65 Feb 20 Comment Another wonderful water drop collision image with a plethora of interesting detail. I am enjoying the color and the reflections in some of the drops of the surrounding area. The edge-on view is also a somewhat different way to present this event, so kudos for that aspect for your capture.

I do find that the image feels overly constrained; being that the actual collision "mushroom" fills so much of the actual images. I would have like to have bit more of the environment that the collision is in. It has an "in-your-face" quality that to my eye is a bit overwhelming. I also feel that the back half of the "collision table" (the cap of the mushroom) is lost some and blends into the bright background. If there were my image I would be tempted to darken the background just a bit to slightly tone it down some, and to allow the "collision table" to stand out a bit.

65 Feb 20 Comment I had some difficulty with this image as to my eye this really was neither a close-up or macro image, so it may not be appropriate for this study group forum.

One definition of a close-up images are images who's subject is roughly the size of a loaf of bread to the size of the camera sensor (close to the size of a postage stamp), while a macro images are images where the subject is the size of the camera sensor or smaller. Why the differentiation? Well in close-up images, one can increase the apparent depth-of-field by reducing the aperture (increasing the f value), while with macro images decreasing the aperture has little or no impact upon the apparent depth-of-field. This is why in macro images we often need to apply alternate techniques (such as focus stacking) to improve our depth-of-field while this tends to less of an issue with close-up images.

To my eye the subject appears to be the torch supplying hot air into a much larger hot-air balloon, and as such is really not a close-up image. This is not to say that it isn't a good image, only that perhaps is not the most appropriate image for this study section.
