Hi

There are a few nice old trees in my area but I don't have a wide lens, so I tried to stich some photos taken with a zoom at 70mm

It's a little bit light in the middle zone - the sky gets lighter, then darkens towards the horizon, which is not natural.

With respect to the unevenness David noted, my guess is that you shot the pictures with the exposure in an automatic mode. While this can work, you usually want to meter, pick an exposure, set it in manual mode, and use that same exposure throughout the series. If you're shooting raw, you also want to process all the pictures the same -- using the "auto" in ACR (for one example) can and will produce differences that can be fairly noticeable. Some other raw conversion programs (e.g. Bibble) make it easier to apply a single set of conversion parameters to a whole series of pictures.

While shooting in manual usually helps, it still doesn't guarantee a good match. The normal variation in exposure is typically on the order of 1/4th of a stop, which is usually fine, but when you're stitching pictures together can produce noticeable variation.

And don't forget to set a fixed white balance, too! (And don't forget to return to normal settings afterwards...)

Besides the technical aspects, this shot deserves praise: I like the way you put it in the confining rectangle, very strictly, and the power of the tree that is shown through this confinement.

Thanks for all the much needed and welcomed advice,

I've been thinking that to improve my photo skills (which need much improving) instead of just walking around just taking snaps, I should pick a project than work on it till I'm happy. There maybe a few post of stiched trees over the next few weeks there are some old river gums around I want to shot before they die due to the drought.

I did shoot raw+ jpg, but the stich was made from the jpg's, I'm still fighting with processing RAW's, after playing with all the different converts, I found DxO optics pro, was the easiest for me to use, now I just need to learn it's in and out. I'll try again with using the RAW's.


Thanks again.
