Hi All!
If your subject has depth, like a vortex marble, how do you get a photo that shows the depth. Mine are frequently blurry in the middle.
My hubby makes them, they range from 1" to 3", the vortex goes straight into the middle. They are encased in clear glass which creates a lense.
In person, they look like they are very deep, but when I photograph them, they don't, unless I show it from another angle.
Maybe it isn't possible, I don't know. I have a Canon Rebel T1i, which is new. Am I asking too much? LOL.
Thanks for your time, Jan
It is possible, but will depend very much upon the lens you are using, the aperture, and the magnification within the frame.
The closer to the marble you get, the less of it you will get in focus. If you use a wide angle lens, then it will be affected less, but will appear smaller in the photograph. Select a small aperture (needs a long exposure time and a tripod, or flash), as this will give you a greater depth of field (DOF).
There is another method that would help, called focus stacking, but this may be a little advanced given that you are new to the camera. Still, if you wish to look it up, here's the link.
Welcome to the site, hope that was helpful.

Thanks so much, David! I appreciate your time to answer.
I will fiddle with that today. I'll practice and see what the camera does for me. Smaller aperture, and use my tripod more often.
I think the focus stacking is quite over my head, but I found that article at the end very cool, with pics, Introduction to Focus Stacking
Thanks again, now I have a direction to go in.

I've never seen one of these so I'm not sure how it reacts to light shining on it, so my suggestion may not work, but worth a go. Try moving a lamp around at different angles (above, to the side, behind) to see what affect it has on the depth when you take a photo.
Are there 2 issues here? You mention blurry in the middle and David has given some pointers there... however, you also mention this:
Quote: In person, they look like they are very deep, but when I photograph them, they don't, unless I show it from another angle.
Does this "deepness" come from the fact that they are seen with 2 eyes and therefore you get the illusion of depth that being seen from a single point (i.e. a camera lens) cannot replicate?
If that is so, then there maybe some tricks that you can do with very careful lighting or use of light and dark card to add or remove light to help sculpt the vortex inside. Without seeing one and having a play at the lighting it's hard to say really.
Uploading a shot or two into your Portfolio might help people come up with some ideas for you Jan.
Oh, and welcome to the site
It may also help to hand tint the parts of the image that are closer to the view with a warm tone and tint the parts that are further away with a cool tone. This lends the illusion of distance. If its subtle enough it will be subliminal.
