Farther along in the RBG, as part of an art and sculpture display, this tree was a red oak that had been destroyed by gypsy moths. It was cut down and the "resulting work is the entire tree, from the largest sections of the trunk to the smallest branches cut into cubes and packed as a solid block in its original location".
The original picture turned out a little lifeless (no pun intended) and this effect is the result of it being warmified and sharpened, then a lot of soft focus was added to add concentration to the stump and the block.
I'm not generally a huge fan of photoshopping. Sometimes a photo could use a little bit of help, but I find too much saturation annoying rather than enlightening, and often these 'soft focus' ones just make me want to rub my eyes and squint.
BUT, there seems to be some amazing techniques out there that I knew nothing about, which make my attempts here look very basic and simple. I urge anyone who is interested and who doesn't normally check out the other SundayStills contributers to do so and see some of the creativity that photoshop can produce - if you have the right program!
