The Microscope

And the microscope big difference is this is all in one mean, you got the focusing stage built in. You've got a nice x y movement. You can see what you're looking at. You got the objectives on it. So it's essentially, uh, these tabletops setups, but really refined, really fine and really, really fine movements. Um and allows you to work at it even higher magnification. You could do things like the grooves on a record. Okay, old thirty three rpm record. That's what the grooves look like, ok, you can get it instead of doing the insect. You can just you khun d'oh details on the leg. This is the leg of ah, aquatic insect. And how did you find creatures that you never even knew existed in the media? That makes a shell? These are things you can't see now. This is this is the next level that we've gone into the microscope. Little little little creatures that are feeding constantly with the cilia that move around dia tom's that are that are just gorgeous. Um, aliens from outer space or right t...

here in your backyard in your birdbath. Okay, this basically is the microscope. These are the components it's, easy toe to see this. You had the objectives you have the viewing eyepieces cameras mounted up top you have a stage focusing everything is there all put together for your very precise, very fine movements the lighting typically is trance illuminated in this type of comes through the base and you have this one has a vertical illuminated on it so what can you do with the microscope? The lighting is maybe a little more limited because with the other pictures were lighting it like a little mini studio we've gotto think sit up and we got our lights and are expensive ikey lights set up so you're lighting it like a little studio subject here you use lighting situations or lighting setups that are provided by the manufacturer this is the common one this is bright field every microscope gets going tohave bright fields so this is a mosquito wing on bright field you have a white background okay and the light comes from the bottom goes to the subject dark field is another very common easy to set up doesn't really get a condemned a special condenser for you khun do it yourself like I said a bright field you have a black background on this subject still illuminated very dramatic it really brings out certain subjects this is a snail eggs on dh this is a dark dark field so this is a a lighting technique you can modify dark field a little bit and it's called grinberg instead of having the black background you have you can have a colored background this is, um mosquito larva with a dark blue background sort of dark field but it's really ryan berg crossed polarizer a lot of materials you look at a mexican by refrigerate if you put a polarizing on top polarized on the bottom and jiggle it around a little bit things light up like the muscles in in an aquatic insects okay vitamin c crystals are very buyer a fringe and see you get these dramatic colors blue food dye crystallized by refrigerate crystals across polarizer uh plant aquatic plants, cell walls by refrigerant this is d I see this is now a little more exotic this a little more expensive level more that's a lot more expensive but it's a very nice type of illumination it's something you know serious you know biological microscopes love and strike for uh but it's a little bit hard to come buy used and it's quite expensive new so we don't dwell on that too terribly much this is phase contrast used to be used a lot it's not the greatest for photography but it does allow you to see things that are usually very, very thin um like amoebas and things like that bacteria but photographically I I just don't use it that much anymore I'm not too excited and then we have the reflected where we can take the kind of thing we're doing with these tabletops setups to sort of the next level. Um, a, uh, the camera chip. You can see the rgb, uh, filter's on the lower left and somebody electronics in the upper right.

Class Description

Photomicrography (photography through a microscope) and photomacrography (using a hybrid combination of microscope optics and conventional camera equipment), opens up vast new areas for exploration. Learn about the tools and techniques essential for exploring these fascinating approaches in Beyond Macro Photography: Into the Microscopic World with Charles Krebs.

In this class, you’ll learn about the most common equipment and techniques used in photomicrography and photomacrography and the difficulties photographers face when shooting such technically challenging images.

Charles will discuss the imaging characteristics and complications that arise while working at high magnifications and he’ll offer solutions for dealing with diffraction effects, severely limited depth-of-field, and vibration problems.

The world around us filled with fascinating subjects too small to seen with the unaided eye. Macro photography provides a peek into this world, but to fully appreciate many smaller subjects it is necessary to experiment with specialized techniques – find out how it is done in Beyond Macro Photography: Into the Microscopic World with Charles Krebs.
