Travels with an orb

By Tianshi_angie
I have put the orb much closer to the tree and I have tried to focus on the orb - but that seems to be quite difficult - possibly because the orb has many focus points! BUT solved the problem of how to hold the orb in place - it is on a gorilla pod - which has a flat screw - which fits exactly the holder for the orb! So not super safe but much easier to deal with - so camera is on tripod and remote connected. Now things are easier. So please - suggestions and gratefully received.

Two suggestions, Angie:

1 manual focus; and
2 camera very close to the orb, and both a good distance from the tree.

Yes that is the ideal John but this was one of those 'experiments' - which I had to try! I was manually focussing but it would seem that either the orb - because of its shape - throws everything out of focus, or that the focus point in the orb is very small and I couldn't find it!. Obviously if there is one it would be in the middle (I think) but the magnification doesn't give me any idea where the middle is. But now that I have such a good solution to placing the orb the logistics are easier to play with.

Angie try holding a wooden ruler of pencil, level with the centre of the orb, then focus using the rear screen until the ruler/pencil is sharp at the side of the orb, you then have focus on/ very close to the centre of the orb, you can then do the same to bring the focus closer or further from the centre which ever is better. for the shot/look you are after Smile

You won't believe this Ian but I have two rulers - one wooden and one metal and I can't find either - the elves have eaten them or are playing tricks on me!!! But I get the idea and will investigate a substitution. Thank you - so much to learn!

The image through the orb won't necessarily be within the same plane as the orb. It may be way in front or (my first guess) way behind it.

I may have to go and experiment with my Lensball - if this happens, there'll be a blog...

Focusing manually is immune to whatever is going on in the orb, you should see whatever you focus on sharp on the screen before you take the shot, However, it wont look sharp IF the lens is too close to the orb.

In this mage, the orb at the front is reasonably sharp here, so somethin worked, At f/19 the rest of the tree is trying to be sharp! If you wanted out of focus blobs, then use a wider aperture, and do what dudler said, - orb and camera further from the tree.

I've played. And I was wrong about where the image through the globe is, optically. The long and the short of it is that the image visible in the Lensball (which is very similar to your globe) is in the same plane as the ball. With a 45mm Samyang on my camera, that put the ball at 40cm, the minimum focus distance. I shot wide open for differential focus, and I'll put it up as a blog tomorrow.

To get closer (which I'd ideally want to do) will take closeup gear of some sort - sets of cheap close-up lenses are around a tenner...

WOW that is dedication! Thanks for that John.

Oh - I have one of the raynox clip on 'close up' lenses - Later I will try it out - but I am doing some cleaning at the moment. Badly in need of it so it is taking me a long time, but exhaustion is beginning to get the better of me so I may have to give up before it is finished - but there is always tomorrow!!
