Re: Amoeba (video)

Insects with a compound microscope are possible, but only if they are sufficiently small and transparent. Otherwise you see only black. Wings of flies, bees etc. are great to look at. To brighten up the insects, you can place them in a solution of KOH (others also use NaOH) or lactic acid. If they s...

Re: Amoeba (video)

But, correct me if I'm wrong, most of the really good photos I see on this and other groups seems to be taken by DSLRs, (and I supposed with higher quality microscopes). DSLRs do indeed have one significant advantage over dedicated microscope cameras and this is that they generally have a much high...

Re: Amoeba (video)

I believe all would yield better resolution than the Amsco USB camera. 10MP is a lot, much more than you "need". Do not forget, that many microscope objectives and specimens are not even able to provide the quality that the camera is able to capture (in other words, not the camera is the problem in...

Nice. What is "Wart"?
It is a small outgrowth of the skin. Most of them harmless. Some are caused by viruses.

Re: New filters

Hello, a few recommendations: 1. Make the filters black and not reflective, it might otherwise damage the lamp of the microscope (halogen bulb overheats, if you use halogen). 2. When making oblique illumination filters, I found out that the effect is stronger if the cut out does not go all the way t...

Re: dropbox test

no, not shared. Every folder can be shared anyway, but this is not done here. Call the folder "public" (without quotation marks) and DropBox should automatically recognize it as special. No additional sharing is necessary. Put the folder into the root directly (the topmost level).

Re: dropbox test

Create a folder called public in your Dropbox root directory (if it is not already there). Place your images into this folder and then you can link to them.

How do you actually do the background cleanup? Do you select, and copy-paste the specimen on near-white background? Or do you manually erase the "dirt"?

You can upload a picture to an external image hosting service (Photobucket, Flickr, etc) and then include the link to the picture inside the post.
