[Notas - Normas] Nota do Artista
Yesterday I uploaded a bonus photo as a workshop. The critique I received from Evelynn made me decide to post another close up of the travertine, but this time as the main photo. Others also appreciated the bonus photo, so hopefully this one will be critiqued the same way.

I had some difficulties with this photo when I made it and today with the enhancements.
As you all know photographing a clear object causes a lot of reflections and exposure problems. I used my CP filter to block most of the reflections, but I did want to have some reflection in it otherwise you wouldn't even see the water. So I opened the CP filter untill I saw the reflection.
I had most problems with the USM in my post processing efforts. It was either too much or not enough. So I really hope that I came close to a sharp, but not oversharpened, photo.

The rock travertine is a natural chemical precipitate of carbonate minerals; typically aragonite, but often recrystallized to or primary calcite; which is deposited from the water of mineral springs (especially hot springs) or streams saturated with calcium carbonate. When pure, travertine is white, but often is brown to yellow due to impurities. When carbon dioxide-rich water percolates through rocks in limestone areas, the water dissolves the limestone and becomes saturated with it. When the water resurfaces later, the sudden drop in pressure and the change in temperature cause the water to release the carbon dioxide gas, much like fizzy drinks. The calcium carbonate then recrystallizes, often over minute underwater plants. The resulting rock is typically quite porous with numerous cavities. When exceptionally porous it is known as calcarious tufa.

Hello Niek,
I can totally appreciate the difficulties you had with this shot, both in the taking and the post processing. I think you did a great job, and thanks for the explanations.
The texture is just amazing. AND I can clearly see the water running over the rock. Quite a technical feat. Congratulations.
Great composition, sharpness, light, and colors. TFS. : )
P.S. What is travertine?

Wow, Niek. I missed this incredible detail. But this shot renders it perfectly. The compostion is really pleasant with all those shapes and curves. Thanks for showing us.

Hallo Niek,
Leuke, bijna abstrakte compositie. Fijn dat je uitlegt hoe je de foto hebt genomen. Als ik beter kijk kan ik uiterraard het water voelen, meer dan echt zien.
Well done and TFS

Wow that is a tough shot to handle Neik. It's also even more challenging having to resize the photo for posting here, so even more detail is lost. Maybe take some food colouring with you for the water next time hehe.

Wow, what a cool photo Niek. Very interesting subject and well handled, exposure, light, texture, color, sharpness, composition and enhancement...there...did I leave anything out? : )

Thanks for sharing both the photo and note.

Evelynn : )

Really interesting rock formation again Niek!
So unusual, it look like a piece of glass art.
Wonderful golden-yellow colours, nice composition the way the water flows down the rock. Nicely framed and interesting notes too.

Hi Niek,
Wow, amazing crstalline structures, almost as if Mother Nature herself has sculpted a landscape scene. Excellent work on cutting down the reflections, great detail and colours. Excellent shot with an interesting note. Great work!
Regards,
Adrian

Hi Niek !
This isa fabulous picture ! I love the textures and the colors very much, and I can see the water running on the stone formation. Details, exposure, colors, composition, everything is excellent here. Very well done !

Very good shot Niek,

I really like the composition. The flowing lines and seams make a good composition. Great shot, well done.

Hello Niek,
Amazing textures and the details come out very well!
Interesting lines in the composition, attractive colour palette!
Greetings,
