An appealing image that meets the challenge
The fog has added another quality to your image by softening the bright glare from the fireworks and the lights and the water reflections add yet more interest to the image. I particularly like the fog halos around the lights and their reflections, your composition in placing the fireworks to the right has enabled them to balance each other with the blue blue lights mimicking the fireworks shape, good 'seeing', well done.
As regards the challenge brief of f8 this is probably not the best way of making the most of the aperture, for the purpose of the challenge I think it would have been better to show its use through DOF. The choice of subject, there is nothing here to identify with f8 or f16 they would both look similar.
Thanks for your submission, Sid |
