  1. The Hummer Thread Vol.2!!!

    Sheila, interesting concept. There are water immersion and oil immersion objectives that are available for microscopes. With my 40x objective, the front glass element is extremely close to the subject. Almost looks like it's touching the slide. I guess you know this from your work with microscopes - that when using the 40x objective, you can only use the fine focus knob. If you use coarse focus, you'll ram the objective into the glass slide, breaking it. I'd imagine with a 100x objective (which are usually used for oil immersion) the distance between the front glass element and the specimen would be even tighter. Ive never used oil immersion objectives but I believe a special kind of oil is used with them. Both the front glass element and the specimen are immersed in oil. Apparently, if such objectives are used in air, the optical quality won't be that great. The oil is needed to achieve optimum quality.
  2. The head being cut off does bother me. However, the composition in which the model is looking into the narrow side of the frame is used in a number of movies. Placing the actor / model in such a way within the frame sometimes suggests some kind of tension or anxiety - at least for movies. Probably not the case here.

    Sheila, I'm not surprised that 500mm lens rarely stays in your camera bag! Jeannette, thankyou! This creek water is turning out to be quite productive. I had another look at it under the microscope this evening. This time around, there were mainly ciliates that were hanging around the vegetation. No sign of the cucumber-shaped things from yesterday. I really wanted to record footage of the larger ciliates but they were way too mobile. I couldn't properly focus on them because they wouldn't keep still. Focusing on organisms under the microscope in general is a bit tricky. Because to get accurate focus, I have to digitally zoom in on the subject in the camera's LCD screen and use the microscope's own fine focus knob to adjust focus. So during focusing, you've got a highly magnified view of the subject with an extremely narrow field of view. And it doesn't take much at all for the critter to quickly move out of that field of view before you've had a chance to focus on it. Really challenging when trying to focus on moving subjects and just about impossible with quick, rapidly moving subjects that swim all over the place. However, I did manage to record footage of some tiny little ciliates which generally weren't quite as mobile as the larger ones. There was this one ciliate which was chilling by a piece of vegetation / minding it's own business when another ciliate comes along and bumps into it and the two go swimming off together. I was hoping that there was going to be another one of those worm things but no such luck.

    Sheila, a 500mm lens? Wow, awesome. A great wildlife tool no doubt. Years ago, I bought a 600mm mirror lens. And at one stage, I had a 400mm lens with the M42 screw thread mount but that seems to have mysteriously disappeared. Turns out that some of those stationary cucumber-shaped things under the microscope weren't stationary after all. When I fast-forwarded the videos, I can see them moving extremely slowly. I'll have to shoot them in time lapse next time.
  5. I would love to Know how

    Perhaps the title of this thread should be changed from "I would love to know how" to "I would love to know how to spread more spam."

    I managed to collect some water from a creek close to the main town. Was really interesting looking at the vegetation from the water under the microscope. I saw a worm-like creature in the water sample too which was really cool. It was wriggling around like crazy - wouldn't stop moving. Looked a lot like a nematode. I tried to record footage of it but it was too quick. Eventually, I lost sight of it and tried to find it again but couldn't. There were also these cucumber-shaped things. Not sure if they were diatoms. Most of them were stationary but a few of them were moving very slowly. I got footage of the stationary ones but then my camera's battery went flat before I could record the ones that were moving. I'll take another sample from this water tomorrow for another microscope session.

    Jeanette, I'm sorry to hear about the passing of your uncle. Sounds like your family did so much for him and I'm sure he appreciated all of your efforts, support and companionship.
  8. $1.50 Video Sale?!?!?!?!

    I agree. It's ridiculous. Not sure if there's an option to opt out of these though.
  9. $1.50 Video Sale?!?!?!?!

    Sadly, it's not a mistake. It's part of a new pricing plan introduced by SS not too long ago. If someone buys your video as part of a large clip pack, you get paid peanuts. Looks like you're one of the unlucky ones.

    That's a reasonable assumption.

    Sheila, that must have been quite a shock. I'm glad you were in safe hands in San Fran.
  12. Software for .mov

    Another question about One Shot - can you choose between interlaced and progressive options when you're exporting?
  13. Why do you use all caps when you're typing the title of a post? It makes it seem like you're shouting.
  14. Resurrecting old photos from film or slide negatives

    With regards to submitting a scan of a slide as vintage, I don't think this is always necessary. It depends on the age of the slide. If it's a very old slide that clearly captures a time period from long ago, yea sure. However, in some cases, a slide may have been exposed within the last few years or the last few months - hardly vintage. Ive submitted several film images to SS and Ive never had to provide a release. In the case of a vintage looking film image, perhaps this might be necessary.
