Image Quality (Three Photographs)

Image Quality or IQ can be a very technical term, e,g, when lenses are measured against each other for resolution, color rendition, distortion etc. Most people would probably just think about the image in general, without technical specifics in a much less objective way. Soft focus, trailing lights, night photography, high and low contrast photographs all have their place. For example, a portrait where we want to flatter the subject might do with less clarity, a sporting event may want to show some movement in the wheels of a racing vehicle and so on. I have done three photographs here of a lily. In the first, all the normal basic fine-tuning was done to exposure, noise, contrast and sharpening. In the second color photograph, I made an effort in tone mapping the file to bring out color and stronger contrast, and in the third I converted the original image to black and white. This raises another interpretation of the quality of an image, how realistic should it be, or should we measure quality by the impact of the photo. IQ, apart from the technical aspect of comparing similar hardware is subjective and therefore hard to define. This is why I do not use the term. Does the photo resonate is a more interesting question.
