      As an old time film user, I particularly like what I can now do in digital. This is an image I created during and after a train ride into NYC. I am extremely curious about using image creation to create that which is not there starting with something or using a camera to take images as the eye sees them, not like a lens.

      @billsaidel Hi Bill, welcome to the forums and good to have you here. Your image looks abstract. Do you use any technique to create images of this type? Look forward to seeing more of your works here 🙂

      Hi Bill, the image you posted looks really puzzling and I’d like to know more about it. Looking forward to seeing your photos!

      So here is what I do to create this type of image.
      First, I have a Nikon D-7100 and I usually use the zoom lens it came with: 18-105 F3.5 open all the way. I also start at 105mm. I use enough neutral density filters to reduce my exposure time to 1-2 seconds at ISO 100-400. I use low ISOs to reduce sensor noise.

      I focus on the buildings adjacent to the train or the scene at some distance. Then placing the front of the lens on the train or car window, when something interesting is encountered visually, I rotate the camera as it captures that interest while the shutter is open. At the same time, the zoom aspect of the lens goes from 105 to 18(or close to that) from the pressure on the window glass. (I’ll also lock the lens at one focal lengthby leaving a tiny space between the lens and window glass.)

      I end up with a rather dull and gray image (see the top of the accompanying image). However, it has all the red-green-blue planes of a colored image and each has a look-up table of 256 levels.

      Now comes creative time. In my case, I use Photoshop 3x in my desktop,but I also have used ON 1 and especially a free scientific image processing program called ImageJ from NIH (which I highly recommend you track down, https://imagej.nih.gov/ij/index.html.) The creation aspect depends upon manipulation of contrast, the number of retained LUT levels per color, insertion Literally I fiddle around with assigning colors to different pixel values until I obtain something that pleases me.

      My wife’s nephew is a professional sketch artist (Dan Springer…he’s really good. Look up his work at http://www.danspringer.net/caricatures.html) and he has been tutoring me about evoking emotions with colors, which colors work together, which create a visual dissonance. I find one can play with one image for hours. A problem,  for I am not yet retired, is that one train ride can result in hundreds of images.

      Any other questions, contact me. I find this technique quite enjoyable for I always end up with something I hadn’t imagined when I started with a particular image.

      I’m also beginning to post images taken with other ideas in mind. I’ll have them up as soon as I figure out easy posting in LightStalking.test image

      Here’s another style I use.  My profession is as a visual neurobiologist. I would like to figure out how to use a camera like an eye. What I mean by that is the area each eye sees (its visual field) is not homogeneous. One sees better with the region of the eye called the fovea and not as well in the surrounding visual area (the peripheral visual field). The peripheral visual field is exquisitely sensitive to movement so I’m trying to figure out how to emphasize detail and movement simultaneously in different areas of a photographic image.

      Here is one example so far.traveling test images

      Finally, there is the straight, not much manipulation, traveling car images. This one I took in the fall. Again, I used about an 18 ND filter so my exposure time was 2 seconds. (My wife is not so copacetic  when I drive and shoot at the same time, but I’m a guy. I can pretend to multitask!) Fall Colors

      This looks like a long process Bill. Thank you for sharing this with us 🙂
