One Plus One Equals...

I am working on my lecture for this years American Osler Society's Annual Meeting to be held in Toronto in early May. As I was searching through the Medical Annals of Maryland, I realized that there is an image of the portrait of Tristram Thomas that we acquired from the University of Maryland's Medical Alumni Association a few years ago. You can read about it here. 

I decided to play around with Photoshop and combine the two images. The 1909 image from the Annals is much more detailed than the actual painting, which desperately needs to be cleaned!

Here's the 1909 image:

Here is the original painting, which is lacking a lot of the detail in the above photograph.

and here is the combination of the two.

I still need to refine it a little by making it a mosaic, but you can get a better idea of what the portrait will look like when it is finally cleaned!
