Hand held, the vertical alignment goes off after the first shot (i.e. the left one). That aside, the photos merged perfectly. Only a little dodging required on the ground leaf cover in the 3rd at the 3 - 4 join.

the distinct 'Y' shape of this tree caught my eye

The softness of colour in the original reveals the uncoated Xenar lens produces a surprising amount of flare.

This can be compensated for in Photoshop by adjustment of levels and Local Contrast Enhancement.

As with the oak trees panorama these are hand held shots. The problem for the photographer is to keep the lens in the same position in space for each one. Without a tripod this is extremely difficult, and especially so with a folding camera due to the need to remove the camera from the eye to wind-on the film as well as looking away from the scene to read the frame number in the little red window. Even using an DSLR with motor wind there is invariably some vertical misalignment. Hence, preparation by repeatedly framing of the shots to memorise the position of key features, especially in the corners, is essential.

In this case the first (left hand) shot was framed as I wanted it, but vertical alignment goes high on the second although, curiously, second and third shots are well matched.

The final result should have been a wider view but I gave far too much overlap of right and centre frames. As a result less than 25% of the centre shot gets used. However, too much overlap is better than too little.

Merging was near perfect, only requiring some reduction in density of sky colour of the centre shot at the left/centre join.

What's good about this technique is that you get the angle of view of a wide angle lens but with the perspective of a standard lens. i.e. if a 24mm lens had been used the angle of view would have been the same but the trees in the background would appear to be twice as far away.

( the Xenar's flare problem is again all to obvious. A record shot rather than great photography. ....... just using up the last frame on the roll!)
