I usually use a Nikon D100 but it just happens that these two were from automatic cameras. Glad you enjoyed the images. The windshield shot is with my Coolpix P90.
Exif data is as follows-
Shutter Speed,1/178
F-Stop,4.0
ISO Speed,64
Resolution (DPI),300
Lens Focal Length,4.59
The foggy scene is from my husband's point and shoot Kodak, to my surprise!
Shutter Speed,1/468
F-Stop,2.7
ISO Speed,80
Resolution (DPI),300
Lens Focal Length,6.0
I'm not familiar with "focus stacking" but I would love for you to enlighten me. HP Photosmart is what I usually use to create and save multiple exposures only because it is such a simple program. I've also used Photoshop (it bogs down my already bogged PC with its huge size) and my new favorite program is Capture NX2.
My successes have been with underexposed photos with good composition. "Perfect" photos don't seem to improve with HDR processing and neither do brilliant blue skies or waters.
I viewed some of your photos; I admire your work. I am just beginning to post as I learn the workings of this site.
