All the shadows in this picture are in fact parallel.
If you measure each individual one they would all be in the same direction.
That's photography for you.
When you have a moment, could you please respond in any way you see fit to the claim by a poster earlier (sarliv on this thread: [You must be registered and logged in to see this link.]) today that you and me are one and the same?

I'm sorry to keep on but how can lens settings affect the direction of shadows ?
Focal length changes the field depth of the picture.
There's a brilliant scene in Jaws II where it's used to great effect (the background zooming away effect).

Where was this photo taken, an aerial view would be important to assess the straightness or 'curviness'.
At least with the pool photo we have an overhead view and can determine what is where and relate it to the information on the photo.

Here is another one that backs up the previous one with regard to position. This time the inner two lines represent the direction to the shade's pole and the centre of the tree trunk, which happen to be equidistant from the edge of the frame. The outer ones are 19.6 degrees apart which is the field of view on that camera with a focal length of 21.7mm.

Drawing a line from top of head to tip of shadow will give you a true sun angle if, and only if, the shadow was photographed broadside-on. View it from any other angle and the shadow will be foreshortened (that perspective thing again), and the results will be utterly meaningless.
The posts' shadows in the above scene were pointing in the same direction and had the same length, but that was not how the camera saw them. If we're going to find the sun's height from the apparent shadow length, we first need to find out where the shadow is pointing, and by how much.

However Tony I posted my view on the positioning on the "Another look at the Last Photo" thread starting around page 24, but that was immediately derailed onto "suit photo".
I've reproduced the summary picture below of the direction I believe.
This takes into account:
- A calculation of the distance of the photographer from Gerry detailed on that thread. I hold my hand up that it is an approximation of the distance due to the assumptions that have to be made, but should be the right order of magnitude, and on plotting it looks to be reasonable
- Taking into account a direct line from the photographer, "through" the pole of the shade, should line up with the corner of the paved area of the main pool
- And taking into account a line to the right of the tree should be just to the left of one of the main pool shades
- Note the image used is June 2007

rustyjames, thankyou. I had seen your post and it was that which made me go looking further.
I add, above, the site for the last photo.
I agree your camera (wo)man position as pretty spot on.
With Maddie looking over her left shoulder, sitting on the edge of the pool, her face would be pretty well southerly facing. Gerry's line of vision being just fractionally to the left of Maddie's line of vision.
I look forward to your independent observations later.

My posts have been about the angle of attack relative to the sun and the geographical orientation of an object and a fixed time.
Once those points are established one can work out what light will be shining where and what shadows will be cast.
Any 'modern day playing' with photography /distortion in photo/picture finish may be due to a curvature in a lens or some other 'artistic intervention or technically distorting trick' but as I said this is a bog standard family photo, or would like to appear as a family photo, without any other evidence of distortion either within the picture or around the edges of the picture to indicate specialist lenses with distorting curvature.
The only things that are 'distorting' are primarily the long shadow on Gerry's T shirt when his stance, his angle towards the sun, his geographical orientation, determine his shadow to NOT be the way it is presented.
For that I summise that some manipulation has occurred to the photo and in layman's terms, that is called 'photo-shopping'.
The importance of determining whether the picture has been interfered with is to be able to have free run to determine what exactly happened to Madeleine and not try to fit facts into a fixed but possibly incorrect timeline which may implicate the wrong person and lead to a breach of justice.
The reason I asked if the road was curved or straight was that if it is curved then the shadows are completely compatible with a light-source somewhere behind the fence, the shadows fanning out as they respect the curve of the road.
If however the road were straight, then something like the fairground hall of mirrors would have had to have been involved in the production of shadows that fall from an apparently vertical barrier with parallel, juxtaposed bars or wooden posts, and yet do not respect the expected travel of shadow which according to the laws of physics would be estimable.

Re: Analyzing position of sun in last photo
Thankyou for the replies so far everyone.. I hadn't quite anticipated the direction the discussion would be taking :)
@rustyjames - thankyou for the 'findmyshadow' link - I hadn't seen that one before.
@bobbin, thanks for your reply, and confirming the angle of the sun was 68deg - thats certainly what the suncalc software seems to be telling us it was on 3/5/07.
Just wanted to comment on a couple of assumptions I think I'm seeing in the comments. Primarily, that the camera settings would affect the picture being taken, or would affect 'parallex', perspective, angles, that kind of thing:
It is my understanding that camera settings do *not* affect the perspective of an image, so are not important to the analysis being proposed. Specifically, the focal length of a lens has no effect on the resulting perspective of the image being captured. All that happens when you zoom in/out, is that your angle-of-view changes (i.e. how much of the 'image' you can see).
For example, you can take a photo of a subject with a wide-angle lens (i.e. zoomed out), and then take the same picture again with a telephoto lens setting (zoomed in). If you crop the image that came from the wide-angle lens so that it includes the same area that was captured with the telephoto lens - and then enlarge it so the pictures are the same size - the resulting images will be the same. That's right, no change in perspective, by my understanding. They will look like they were taken at the same focal-length, ignoring any loss of quality because of the enlarging process. To reiterate, a wide-angle lens will capture a wider field of view only (i.e. more 'stuff' will be in the photo) but it does not change perspective.
The only time perspective will change, is when the camera's distance to its subject is changes. i.e. when you walk towards/away from the subject. If you use a wide-angle lens, you need to be closer to a subject for it to 'fill' the viewfinder. That's why the resulting picture looks like it comes from a wide-angle lens - because you are closer to the subject.
I will continue studying this topic, it would be good to know either way if such an analysis could prove useful, and will report back if I get anywhere :)

Totally absolutely and utterly wrong.
Even without changing any settings on a camera, you ALWAYS have the issue of parallax and that varies from camera to camera depending on lens curvature.

'Some just don't want to hear'... ahem.
I suggested a simple experiment to prove what I am saying. Would you like to try it? If you have a camera with a zoom, take 2 pictures, one at a wide-angle setting, and one fully zoomed in. Stay where you are for both pictures, that's the important bit. You can review the pictures on the back most cameras these days. Zoom in on the wide-angle picture until the same area is being displayed. It'll look the same as the picture that was taken fully zoomed-in.
All I can say is... try it if you don't believe me.

"Wide angle lenses can help reduce parallax effects because a wide angle lens accentuates perspective"
Anyway.
Are you ignoring the point about parallax?
This IS the key issue as I have been saying over and over and over.
Parallel lines are not parallel in photographs - (see the shadows of railing picture that confused you).
Shadows from a subject in the centre of a picture are going to appear to be different angle to those further to the sides whilst in reality they are not.
Any "science" based on "angles should be the same" is bunk.
Saying the last photo is photoshopped because Gerry's shadow is at a different angle to the tree and background is pure rubbish.

Not sure what's being attributed to me here, but for the most part I generally agree with BlueBag, although I may disagree a little in the post after this one.
For example please see my post on posts (so to speak) earlier showing how the apparent angles of a row of identical posts are different, both in respect to the shadow they cast on the ground, and the apparent angle to the ground. The sun appears as a relatively small disc in the sky and the shadow and the thing making the shadow has to be tracked back to that position.

Re: Analyzing position of sun in last photo
The issue of perspective is the one I (mostly) disagree with. The biggest factor is movement towards or away from the subject whilst changing the focal length, i.e. keeping the subject the same size. In that case perspective will change.
Staying in the same place, changing the focal length and then cropping will give very similiar results - although for example a very wide angle lens will distort the image in a fish eye effect.
Some decent examples here - [You must be registered and logged in to see this link.] and here - [You must be registered and logged in to see this link.]
