Arcella crenulata

[cuxlander]

Hello,

this a nice image of an 124 µm wide empty Arcella crenulata:



It has its name from the crenulated rim of the pseudostome.
Stack of 6, Zeiss KF2 40x bright field, Touptek 5.1 mp Camera.

Greetings,

Very nice image - though I think I have to agree with your assessment that it is time camerawise to gear up.

Hello 75,
couldn't agree more.
I see that you use a Olympus E-p2.
I always thought that micro four/third should be a good solution.
1. do you use it without camera objective?
2. how is the camera connected to the laptop? Can you focus from there and save the image to the drive? (i.e. tethering)
3. how do you adapt the camera?
Greetings,
Hans

I see that you use a Olympus E-p2.

Yes, and though I am happy with it, I have to say that it kicks like a mule (lots of vibration), so I have had to isolate it from the microscope!
I have it on a tripod, and have even had to place rubber rings under its feet.
gekko also has an Olympus m4/3 - he has his fixed to a shelf behind his microscope.
I have heard that some of the Canon models are practically vibration free.

do you use it without camera objective

I use a Zeiss 12.5x KPL eyepiece to project an image directly on to the camera's sensor.

how is the camera connected to the laptop?

I only connect the camera to my computer in order to download the images.
I focus through the binocular eyepieces - best way I think - though you do need precise parfocality with the camera.

Bonjour
Très belle image.
La Canon EOS 1200d est très bien pour faire de la photo au microscope, car il ne crée pas de vibration.
Le mien je le connecte directement sur la sortie trino de mon Leitz Laborlux et je n'est aucun soucis le tout contrôler à distance avec le logiciel EOS utility.
Cordialement seb

Beautifully detailed and rich colors. Excellent imaging.

Very nice; excellent image.

I have heard that some of the Canon models are practically vibration free.

I use a Canon 60D with remote shooting. The mirror locks up so no vibration from that. Still have to be careful with the PC mouse to avoid introducing table vibrations. Sometimes I move the mouse to a separate table along side to avoid any vibrations.

My 2 cents' worth: some (but not all) Canon DSLRs have a "silent shutter" (electronic first curtain shutter) mode that eliminates vibrations caused but the shutter itself (as opposed to those due to the mirror). If I remember correctly, Charles Krebs recommends the Canon 5Ti (but avoid the 6Ti).
As 75RR mentioned, I do use a mirrorless Olympus E-PM2, and in order to eliminate shutter-caused vibration I mounted the camera so it is independent of the microscope.

Hello,
thanks for your comments.
I know that for best microphotos you have to use a DSLR or one with a similarly large image sensor.
(vaselle: particulièrement Canon ou micro four third)
Im am however still discouraged by the complex adaption. Also I like to be able to control through the laptop monitor. Thirdly I do not want the camera separate from the microscope. Having said that, I am still considering these options.
75RR: I am aware that my systems deserves an upgrade. Still I feel that the above photo of Arcella is quite well done under the circumstances.
I am starting a new topic in the "Camera systems and imaging"-Forum about my imminent problems with the Touptec Camera and software, false colors and flickering.
Cheers to all,
Hans

Hi Hans,
Excellent image of your Arcella crenulata, also thank you for your comment on my Difflugia 2-video
on YouTube.
Will be looking forward to your post on ‘Camera systems & imaging’. My OMAX 5MP camera has
Similar problems producing correct colors.
