Just to note that a 'circular-polaring filter was added to the lens for all the photographs shown here. The lens was 'manually'-adjusted during use and I didn't use a tripod. However, for the landscape shots I steadied the camera on top of a fence post.
This first photo is a portion of the Cerro Colorado Mountains just North of Arivaca, Arizona. I made some basic adjustment with the image's brightness, contrast and gamma, bring-out the features in the photograph.
The second photo below showing Baboquivari Peak was adjusted later in Photoshop Elements. I like the resulting texture in that shot.
