First you have to upload it, then you have to select it from the dropdown box to actually include it into the post.

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...

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...

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...

Hello and welcome to the new forum! Glad that you are also now a member (again)!

Nice. What is "Wart"?

It is a small outgrowth of the skin. Most of them harmless. Some are caused by viruses.

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...

Argh!!! I just found out that the picture is only visible as long as you are logged in into dropbox. This is not good. This is really unfortunate. I will try to find a solution for this.
Oliver.

1. Save your picture in any folder on dropbox, does not have to be public (the public folder was relevant before 2012, I have an old account) 2. in Dropbox (in the Web Browser) click on the picture to see the picture on black background. 3. On the bottom right corner there are three dots ("More Acti...

Hmm. I found this one here:
https://www.dropbox.com/en/help/16
They did change something.
I still have an old Dropbox account and the public folder still exists. Now, however, things are indeed different. Will check this out.
Oliver.

I am using computer terminology, and this might be a bit unclear. When I say "root" then I mean the topmost directory in Dropbox. Notice the Public folder in the middle here: http://www.maclife.com/files/u12635/droplink_4.png There is the world on the folder and this means that the folder is treated...

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).
Oliver

Try placing the picture into the "public" folder and then linking from there. The moss picture above is also in Dropbox.

The link of the above picture should look like this:
[img]https://dl.dropboxusercontent.com/u/20001938/moss.jpg[/img]

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.



Oliver

Include the link to the actual image in [img] tags like this:
[img]http://www......filename.jpg[/img]

At the end you need the name of the file.

Hello,
Like every month, I would like to invite all microscopists to contribute images and articles to the magazine. Even short ones are fine! All microscopy related topics are welcome!
Oliver

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"?
Oliver.

There are two ways of making pictures visible inside one post. 1. 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. Copy paste the complete link (including the beginning http://) and then surround the li...

This is unfortunate: There were already two spam attacks one about handbags, the other one about sunglasses. I have now changed the registration procedure and new users have to type in the answer to a microscopy-related question. If this does not work, then I will make registration stricter and manu...

Thank you for suggesting this. I would indeed be grateful if I were given permission to use some of the pictures for the magazine!

Hello, Just a general comment. Having a background in bacterial systematics, I am not an expert rotifer systematics, but assume that there are similar issues/problems. Rotifer classification into families and genera is based, I assume, mainly on morphological criteria and not so much on phylogenetic...

Hello, Put the sample on a slide and allow the water to evaporate. Then put some NPM on top and a cover glass. Then evaluate the result. The drying process can cause shrinkage and the solvent in the NPM might dissolve the cholorophyll of the chloroplasts. But you simply have to check the result, may...

In the "old" forum there were posts in french. I think that most people here interact in English, and posting in other languages might not result in a response. If wanted, I have no problems also including sub forums for German and French, just to keep the forum more easily readable. By clicking the...

One of the things that I noticed is the mirroring of part of the image in the stack (on the left side). I have also encountered this when doing stacks with Combine. Any one have any idea why this is the case?

Wespennest: wasps' nest or vespiary
Haftwurzeln: attachment roots of the ivy

As always, very nice pictures.

Google Bot is visiting the site periodically to index it for Google search. It's a good thing. It is doing the same with the rest of the microbehunter.com website as well. It takes only a relatively short time for a new post to appear in Google search (maybe a day or so). It is registered in a separ...

Manfred,
Welcome (again!) from Upper Austria (near Linz).
in case you do not know it yet, there is also a very nice German forum at: http://www.mikroskopie-forum.de

Ok, 1024 should work now. max file size is 512 kb.
