Wikipedia:Featured picture candidates/Morchella elata asci
- Reason
- A high quality image of the microscopic features of fungi, taken with high quality equipment. This sort of image is hard to come by, and having such a high quality and freely licensed image is brilliant. The image is already featured on Commons.

- Support as creator -- I'll note as an additional comment that this image is also a nominee for a WikiMedia Picture of the Year in the Plants and Fungi category. Peter G Werner (talk) 15:48, 17 February 2009 (UTC)
- Support Very good EV. Makeemlighter (talk) 06:02, 18 February 2009 (UTC)
- Support To noone's surprise that saw me suggesting it to J Milburn as a great photo of Fungi =) Shoemaker's Holiday (talk) 05:38, 21 February 2009 (UTC)
- Comment It's a very nice picture. But is there some way of giving it a sense of scale, like stating in the image description the diameter of an ascus? Narayanese (talk) 22:42, 23 February 2009 (UTC)
- This probably just reflects my complete ignorance in the area, but does "40x objective" not mean that it has been magnified to 40 times its actual size? J Milburn (talk) 22:43, 23 February 2009 (UTC)
- ° Actually, it depends on the magnification of the eyepiece. the 40x objective is usually coupled with a 10x eyepiece, for a 400x magnification... but here we're taking a photograph down the microscope, so we've probably changed the eyepiece for a camera attachment... and now have to figure out the camera magnification.
- Luckily, our task is made easier: We don't know the scaling up applied by the user's monitor, so we literally cannot say the magnification level.
- However:
| “ | Morchella elata... Asci are 200-300 x 15-22 μm and contain 8 elliptical ascospores 24-28 x 12-14 μm which produce a cream spore sprint.

- I'd suggest working that into the descriptions and Image description page. Shoemaker's Holiday (talk) 01:37, 24 February 2009 (UTC)
- 40X objective only means that a 40X objective was used when taking the photograph. Additional magnification in excess of 10X was added by the camera. However, making a statement about actual magnification of an image is problematic, because unless you know what size the image is displaying at, you simply don't know how much the magnification showing in the image is. It is possible for me to add a scale bar to this image, its just that I thought it looked better without one. Peter G Werner (talk) 05:13, 24 February 2009 (UTC)
- Unless the scale bar could be made completely accurate - which is probably difficult at this point - I think it's probably better to just describe the size of what's being shown. Shoemaker's Holiday (talk) 08:10, 24 February 2009 (UTC)
