Solarization

My best solarized print is of some tree branches. There is a grey blob on the left which is the sun, but because I solarized it, you can't tell that it's supposed to be there. I closed my aperture on the enlarger three clicks. I put it in the developer for around 15 seconds then exposed it to light for two seconds. This was my favorite print because the blacks are deeper and the whites brighter than on any of my other prints of the same negative. I think this is because I only closed my aperture three clicks, and on one or two of my others, I closed it more. I didn't change the contrast at all.
