Who can see your viewing activity?
Hello Ruojing your sound is cutting out
For me Ruojing's sound is better now -- @angela is it okay now?
It is better now
are commercially available seeds from reputable seed companies considered acceptable in terms of seed identity?
Sound keeps cutting out
Your voice is still cutting out
Hi, Ruojing, your voice is still cutting off
Will this presentation be available?
Yes, the presentation is being recorded and will be shared afterward.
@czarina I will raise your question at the end of Ruojing's part of the presentation -- it is a good one
Ruojing: from Czarina: are commercially available seeds from reputable seed companies considered acceptable in terms of seed identity?
The webinar recording will be available in ISMA website as well.
Do you have a photography program and/or camera you would recommend?
We use CaptureOne and a Canon camera and lenses
can't remember what model camera it is
Medaline will provide more information for equipment and program
How about the microscopic seeds?
more on that momentarily
Paul L here. I work with the team and can chime in on our equipment. We use a Canon 5dmkiii with a 100mm Canon Macro and the 65mm MPE macro. For smaller specimens, we use a Canon 7d mkii with a microscope objective lens setup, using Mitutoyo 5x,10x, and 20x objectives. :)
Is that 65mm lens a zoom lens?
Tagarno microscope is about $10,000 depend on its model, please also contact to the company
The 65mm MPE lens is a 1x-5x macro lens
Do we have any software or application on the market which could help to compare a database image with a currently shut image?
Have you ever consider neutrual density lens filter?
Thanks for the camera details, Paul!
@Miklós I don't know about that -- @paul, any ideas?
In our current studio conditions and outputs we get, we haven't had the need to use ND filters. Can be a great tool though!
Madeline - have you used a silicone ring light skirt on your imaging scope?
@katherine I have not. Have you had good luck with this?
My stacked images using the silicone skirt have been good. Also, it removes air movement
Can you please provide some details on the stand used for the camera?
@moses let's ask @paul about that
Its is so easy to overexposure when taking seed photos, with the help from the lens filters might help to eliminate the overexposure. Also can help isolate the object from background------Just from my personal experience.
As Maddie mentioned, unfortunately the builder/creator of our system is retired. The system is by DunInc and we use Camlift as a programmed lift to move the camera in increments.
There are many other systems for purchase out there however. Sorry I don't know any on the top of my head.
Taran Meyer, CFIA
We have a similar camlift system.
Thanks for the information Paul. I was instantly drawn to it.
a resource for DIY and hobbisyst stacking setups can be found in this forum https://photomacrography.net/
