Repetition

Very excited to finally make a critique - especially since I know how you feel about flower photos. Lee was exactly right - the flowers were all natural and most of that contrast comes from the BW conversion.

Hello, Lee!, I was surprised I made it to the critique. I´m the photographer who took the glacier bubbles photo that entered the last. The photo is actually taken with my mobile, and is part of a series I shot of closeups and textures on the Perito Moreno glacier, in Argentina, where I worked as a trekking guide. It is an up-down view (zenith) of a very small cryoconite, which is a typycal formation from temperate glaciers, in which there is a whole made by material deposited over the ice. As it is darker than the ice, it warms up with the sun and radiates, so it starts melting and drilling the ice. Eventually, some layers of ice are denser than others, and that dark sediment takes longer to melt the ice while forming a uniform flat surface. In this case, it was a very shallow but rather wide pool, with a depth of about 5-7cm (2-3inches) and probably a width of around 6-7 inches. When you zoomed in you saw two things, a lack of acuity, because the photo was shot on an old phones camera and focused around 2 inches from the bubbles, and the reflection of both, the phone and the clear blue sky on the upper part of the bubbles, which I did not cover with the phone. The big bubbles could have been 4-5mm wide and the small ones around 1mm. They occur at the beginning of the winter, as there begins to be some freezing in the surface of the water, but in the meantime the air trapped in the ice keeps getting freed, but still trapped by the layer in the surface. So, tu sum it up: the dark background is the dark sediment. The blue hues of the bubbles is the result of light refraction on water-based prisms and their corresponding light-absorbing properties. And, by the way, I agree, the photo of the patio furniture IS better. Although I havent thought about the difference in the viewing size, as it could result a bit cluttered, but I like it better anyway.
