[Note Guidelines] Photographer's Note
well for No.101 we have one from the ark as far as I am concerned, taken in auto mode before I learnt to use the camera's other bits, the shooting details were lifted from the Exif file attached to every digital image that comes out of any digital camera and providing you have the original image unaltered you will have those details available to you.

What we have here is a pair of Common Garden Snails (Helix aspersa) mating as you can see from both their seperte male organs joining them, no funny stuff here snails are hermaphrodite which means they each have both sex organs male and female and both are active at the same time (For more details about the sex organs look at this site here. The mating seaon is from late spring when things warm up to early summer, but as you can see from the date 26th June of this it can be a little flexable especially if a dry spring has occoured.when 2 snails meet one or both will inject a sharp calcium dart which also contains hormes which it is thought to help make the reciepient snail use more of the spem packets (spermatophore) passed during their mating instead of those of a previous one, which may be 2 or 3 times before conditions are right to lay the eggs.
The stored spermatophores arestored seperatly to the eggs and are only combined intenally just before laying in a chamer in a damp spot under ground or I have found them under logs and pots.The eggs take a about 14 days to hatch into tiny pin point almost see through little snails. from observation these babies seem to restict their diet to nice soft algae in the surface, they of course move on to tuffer things much to the regret of gardeners the world over :0(((((#
This one has been on file for quiet a while, it has not been posted even to Trek Earth for a couple of reasons, 1st i wanted to know more about what was happening here and needed to do some more research before posting. Also there was a problem with the image, because i was still learning the camera I used centre wieghted average light metering, this ment the camera read the dark shell and the 3litre black plastic plant pot allowing the white of the male sex organs to burn out a little and lose some detail, I tried using burn tool to try darken it to bring up the detail still there, this was not entirly successful so it sat on file till I got PS8 (CS) in which Shadows and Highlight was a new tool found at the bottom of the image>adjustment list,
use the expanded list (you need to tick the box)and try experimenting with the sliders (remember less is more as is usual in PS) and this inclueds colour crection towards the bottom.
burntool at 10% was still used to darken the white bits but this time it worked after S&H
sharpen with USM
crop to size
save to web

Fascinating shot, you have rescued this image well, if you hadn't have mentioned it I wouldn't have noticed the Shadows and Highlights work. Well done.

Snails aren't easy targets even when taken one by one, and you got an excellent result on the two loverboys here with your just F-2.8. Good light, great details and a very interesting note that taught me something I didn't know and would never have figured out by myself - I just couldn't imagine any critter with the privates placed this close to the mouth.. Oh well, you have to keep an open mind, I suppose ;-))

Very nice shot Robert, I like it very much. The strong thing here is to held the sharpnes on whole the photo. It's really a fantastic pof and a good details, the note is great, very good job.

An excellent photo with a very good detail. A unique perspective of something that most people would not see. Great notes!

Very interesting post Robert!
I like your idea of showing this scene from above - maybe photo looks quite strange because of that, but I think it works well and the subject is even more interesting from this angle.
Thanks for posting.

Great image and a very informative note, both about the snails and the PP technique.

The image has excellent sharpness and DOF. Very well done and thanks for posting

Hi Robert, I have been recently due to my work to a farm which was being prepared to grown this ones, maybe I will return with my camera :D. I eat almost every thing, but I dont like "scargots"
Nice to see this scene.

Lovely details and colours on both shells and bodies Robert. Perfect diagonal composition. Very informative note - thanks a lot. I always wonder how different the paterns on the shells are.

Great capture Robert, sharp and clear, good colours, interesting PoV and fantastic note.
Well Done!

Yes Rob this is an interesting shot revealing very nice detail. Well done.

Remarkable DOF for F2.5, Robert. Interesting subject and a rare moment caught. Now this is a "lover with a slow hand" :) Brilliant write up, I always enjoy reading your notes. You leave nothing unaddressed. Great work. Thanx.

You are lucky Rob to capture this scene! I remember Gerald Durrell in one of his books wrote about this kind of activity between snails and how happy he was to see it. It is rather rare occasion to view this kind of situation. Very interesting note completed by extraordinary picture.

And this is good case to talk about critique - I bet for most people on TN this is ordinary scene - two brown snails, no cute cats or colorful birds, nothing special, no need to give points. But if somoene loves biology and is interested in Molluscs, for this person your picture is great.
Sorry, points tommorow.

Good shot Robert of the snails. Details and colours are all very natural and well done. But reading all the Tech instructions - how long does it take to learn all this??

Hi Robert, Sorry, I just do not get around, the site is growing and that is good, but it also means less time to look at every thing. I Barely get time to browse through those who comment on me. This is a beautiful sho, composition wise and also good details, a shot I have also be after for a long time. Details are great as is the note.
Maybe a wee bit more contrast towards underexposure, to give morenood, but that is just IMO.

Personal assessment of the photo: great
Aptness of the photo for the site: excellent
Personal assessment: difficulty for the photographer during the capture: easy shot I think (I was wrong here)
Personal assessment of the note: more than excellent
Robert, I test at present a new and personal way of writing my critics and you are among the first ones to whom I send it.
Any comment will largely be appreciated.
A post like as like them.

Robert, please allow me:

And that's why birds do it, bees do it
Even educated fleas do it
Let's do it, let's fall in love

Cold Cape Cod clams, 'gainst their wish, do it
Even lazy jellyfish do it
Let's do it, let's fall in love

I've heard that lizards and frogs do it
Layin' on a rock
They say that roosters do it
With a doodle and cock

Some Argentines, without means do it
I hear even Boston beans do it
Let's do it, let's fall in love

Great action here; although it clearly is at a snail's pace!Yet very occupied in "love"!
All the same I'm not sure what that says... ;)

Interesting PoV of a basic function. Educational shot!

Tfs, Jay

Dear Robert

Thanks for this educational photo and notes.

I have travelled NESW, but never before seen mating snails, and I add your work to my theme "animals' sex life.

Thanks for sharing
