I suppose the first thing to do is to put the two faces side by side so you don't need to scroll up and down.

Dunno how to make the images come larger !
PLEASE COULD SOMEONE (John or Rob or ...?) MODIFY THIS POST TO SHOW THE OPTIONAL LARGER IMAGE WE HAVE ON A PREVIOUS PAGE? TY
When comparing, I look for widely differing features, similar features and proportions or unusual features.
1) the dimpled chin on the third image is the most outstanding feature, but that alone would not completely convince me because Smithman kept his head down much of the way and apart from when he was near Aoife and maybe Peter the lighting was not good. Even when near them it was a very directional light from above and the lower part of his face might have been largely in shadow, but he might have looked up on seeing Aoife.
I think Aoife compiled the LH picture cos there is direct eye contact and a slight smile on his face. Pretty girl? Did he look up and take a good look at her?
2) The bald head of the third image also appears to exclude the third man. However over ten years have passesd and it is just possible that Smithman is now bald
I think that probably Martin and his wife compiled the RH image cos with the face looking fat, it means that it could be foreshortened due to Smithman holding his face somewhat down ... and the blurred image indicates poor light IMO.
That foreshortening could explain the difference in apparent width of the face. It is more likely that Smithman was slimmer faced as in the LH image IMO
3) Another thing that i notice is the very unusual bulge above Smithmans eyes.
Those bulges IMO point to two things:
i) That Smithmans eyes were NOT deeply recessed, but almost "surface" mounted
ii) That the light was catching the bulges, so therefore he was lit from above. This reinforces the fact that the LH. drawing was compiled by Aoife; She and he were lit by a VERY tall and it appears powerful lamp from above
Now likeness.
1) Both Smithman images show a fairly strong 5 o'clock shadow on the upper lip
2) Both Smithmen have similarly shaped eyebrows, altho the RH mans are less well groomed than those of the LH man. Could this be because of the difference in lighting and angle the head was seen at by Martin Smith??
3) Both Smithmen have down sloping eyes. The third mans eyes are level with each other and NOT sloping
There are other obvious differences between the three, but I think I have the main ones, except I haven't mentioned
a) the Jaw line. If looked at with his head tucked down, then the RH mans jaw line might well have bulged out ... and would be partly out of sight in any case, whilst if seen full face by Aoife it is likely to be more correct .... but perhaps some uncertainty.
I wonder, was the little girls head and shoulders close to Smithmans face and partially blocking ?Aoifes view of his jaw. Better to leave the image woolley / unfinished rather than
draw in a definite line and give out potentially incorrect info?
If I were given the task of deciding which image was likely to be most correct, I would go for the LH. one (?Aoifes image?), because it appears well lit, clear and full face rather than bent down as the RH one appears, which distorts the image.
I personally would put the third image on the back burner, but not trash it. Why? Becauwe if there were three images I had to choose from, this third image was less like the other two IMO. Two out of three is some confirmation IMO
Sorry this is so late and out of phase with the thread.
