Banana stem section [Large file: 3.6 Mbytes]

[gekko]

Just to show that I am not completely averse to sectioning , I am reposting an image that I posted a long time ago on the old forum. It shows an unstained radial strip of a cross section of a banana stem, starting from one edge at the top to slightly beyond the midpoint at the bottom. I used 16 images taken with my 4x objective and stitched in Photoshop Elements.   Edit: Please see below for an explanation of the image size and to see the full size image.

... and I scrolled and I scrolled and I scrolled! :) :)

That is the Eveready Bunny of bananas.

I didn't know you could take landscape portraits of a banana!

(That is a great image gekko!)

[einman]

Very nice and clear!

75RR and charlie, sorry guys .
Thank you, einman.

Wow, great image! I guess I missed it the first time around.

Everyone should anticipate that a picture of a banana is going to be long and narrow..... Duh!

Very cool Gekko! Lots of great details and structures to study. Great technicals all around.

Well done!

Impressive. Now you have to section something new.

Beautiful image, the colours are superb. Loads of detail and interesting tissue too! Now then, Jim sounds like he's ready for a sectioning-fest - go to it gekko! You two chaps (gekko & Jim) are producing some fine sections for us to enjoy - let's have some more, they're a real treat!

Very nicely made gekko, superb clarity.

How big is that picture - how did you fit it within the posting limits - it looks huge!
Great post!

Tell him Jim! As Mr Holmes may say - 'the game's afoot!'...

charlie, einman, CE, Rod, JimT, and John B, thank you all very much for your kind comments.

CE, the first time I posted this was about 2 years ago.

JimT, thank you, but I think I am just too old now: this was sectioned in my younger years when I had better vision and steadier hands

John, many thanks for your kind comments as usual. I wish I knew what I was looking at (other than it was from a banana stem). You asked about the file/image size: image size is 780x5324 pixels, and the size of the file I uploaded to Photobucket was 4 MB (I don't know, though, whether they compress it). I don't think the limitation on file size applies to images hosted on other sites, as only the link is posted in the forum, which I think takes only negligible space on the server.

That's an interesting way to put a picture into a post, I'll have to have a go. Well gekko, you've still got those beautiful sections under your belt, and there's plenty to enjoy if you can't make them yourself now, that banana is a work of art I'd say, that's how good your sections are!

This is remarkably good. I really like the unstained quality of it and it's 3 dimensionality. Masterfully photographed. When you start at the top, at the dermal tissue and slowly scroll, it kind of gives me the impression of one of those soil strata sketches, that describe the topsoil, A horizon, B horizon etc.

[KurtM]

Yep, I'd have to call that one of the most remarkable photomicrographs I have ever seen. Just as with an actual viewing through a microscope, one may "go exploring", which is practically unheard of in a single image! Thanks for posting, the span of two years has done nothing to lessen its impact.

It also makes me hungry for a banana.

John, thank you!
apochronaut, thank you very much! I am very pleased that you liked it.
Kurt, thank you very much! The problem was that I wanted to get an image large enough to show sufficient detail and to give a good idea of the whole, and, at the same time, I wanted it to fit on a regular monitor. Since the section had radial symmetry, I took overlapping images of a strip starting from one edge to slightly beyond the center, and then stitched them. Fortunately, when I uploaded it to Photobucket it accepted the whole thing. The Nikon 10x/0.45 objective gave an excellent image.

A long time ago (February, 2014) I posted a stitched image of a banana stem section, and I reposted it in February, 2016, above). The section is on Photobucket, but recently Photobucket started to no longer keep the size as uploaded but resizes the image (up or down) to match the size you selected for linking when you uploadeded it (max 1025x760 pixels). Consequently I no longer use it for hosting images. You can see in the original post above how it now shows the image that I uploaded in 2014. Today, I uploaded the same file to imgur as a test to see if it actually keeps the image size when linked to, and here is the result (which explains 57RR;s original comment ).

Nice to see it back again! :)

Many thanks, 75RR and seb.

I really like the uniformity of brightness & contrast through out
the image, excellent.
