One nice use of a large sensor digital camera is to use it with old Petzval lenses.

 

Girl with cat, modeling lamp, 4.75 inch long A T Thompson, Boston Magic Lantern Lens (Darlot France)-- modified with sepia and added noise. The original image was very smooth without noise. The lens didn't cover the sensor, so a black oval was added around the image. The image circle was not a circle, so I assume there was some off alignment happening. The cat was moving a bit. I'm waiting for my larger Petzval lens to be mounted, which appears to offer a large image circle.

Here is what the image mostly looked like before editing:

And another image with the lens:

Final focus was achieved by asking the model to tilt her head a bit forward or back till one of the shots seemed in focus.

 

Pre-shot: used a calibration frame to correct for the lens and for dust on the sensor, which brightened up the corners that would have been black otherwise, since the lens image circle didn't cover the corners. After shot: cleaned up some noise, enlarged the image, sharpened, added noise and blue effect with some texture.
