I apologise for the late reply.
I’ve tried to find something as specific to what you have asked as I could.
• Warning /!\ This post contains:
When looking for the reference in mind I was having trouble finding the correct image online, instead I have scanned some images from a book, and included an extract from it.
This is one of my personal favourite artistic reference books, and I highly recommend it for anyone who is interested:
All images are from the records of the Institute of Child Welfare, of the University of California, Courtesy Dr. Nancy Bayley.
Plate 88 (Below)
Plate 89 (Below)
Plate 90 (Below)
Plate 91 (Below)
”Plates 88 and 89. Phases in the development of a growing boy. The pictures were taken at at approximately two-year intervals under precisely the same conditions - the same distance, standard frame, ect. They are therefore directly comparable for proportions. These photographs, and those of the girl following, were taken at the Institute of Child Welfare at the University of California, and are used through the curtesy of Dr. Nancy Bayley.”
”Plate 90 and 91.- Phases in the development of a growing girl. The scale of this series is slightly larger than that of the boy. Within the series, the pictures are again directly comparable.”
I realise this may not be exactly what you are looking for, but it it is the closest thing to a photo reference chart that I can imagine.
As for older characters I would like to point you in the direction of this post [x]
Which is another question that our blog was asked.
”Do you know any good tutorials for depicting aged characters?”
The post features some charts for the ageing figure;
(Though admittedly it was harder to find an ageing female then it was to find an ageing male so the post is lacking on that level.)
If you do need images of literally the 13 year old boy and 40 year old female for your own work, I suggest (as odd as it may sound) looking to casting websites, or even dating websites.
Actors/non actors will put up photo references for themselves and you can look up a variety of faces under whatever age you are looking for.
And if you find no luck there, google images never fails.
