Hi folks, Ive come to a decision!
Id like to thank everyone who participated this round, particularly in light of the conversation at the beginning. I trust that subscribers and non-subscribers alike will be keen to continue participating in the future.
Thanks as well to NedL, for helping barbara ann with the process of loading to the thread.
Ive carefully reviewed all the submissions, and my comments follow:
First, the 25 images in the APUG gallery:
Member - Title - Comment
nsouto - Holiday - Great timing, nice colour and it does tend to transport one to another place
macfred - under construction - More great colour, and it certainly suggests play to me
Bertus - Suggestion of a Ruin - A wonderfully dark and somber image, with a nice sense of photographic tension and some mystery - when I thought of this theme, I expected to see mystery!
JPJackson - Old Chestnut Shack - It suggests permanence, and is a very attractive shot
nsouto - The Power of Suggestion - Nice colour, and it is a great illustration of how photography can suggest that things are one way (of similar size), when in fact they are different. Nice use of the photographic medium
TheFlyingCamera - Lamp Post, Kennedy Center - A nice use of abstraction. It is a photograph of the somewhat commonplace, but without the title, it probably would have suggested many different things to different people.
barbara ann - Champagne for two - This was untitled, so Ive given it a title. It does a fine job of suggesting celebration. Or maybe something more intimate as well.
barbara ann - Fungi - Again, this was untitled, so Ive given it a title. Nothing like the suggestion of warm and dark and moist ....
barbara ann - Netting - Again, this was untitled, so Ive given it a title. The netting in front, with the blurred details behind suggests capture to me - another effective use of mystery.
NedL - kick back - A fun pinhole image. It suggests the beach to me, but even more it suggests a dogs view of the beach (to me!)
TheFlyingCamera - Gravelly Bend, Rock Creek, Rock Creek Park - This suggests serenity to me.
NedL - Sand, Sea and Sky - Another fun pinhole image. It suggests another world to me!
sly - How About A Bike Ride? - I like the shapes and detail and symmetry of this photograph. I really like the mystery as well - where are the riders? Are they kids enjoying their summer, or? Id bet this would work well with lith printing (hint!)
sly - An Ocean View - This is highly suggestive

. There are so many things that arent there, but are hinted at. Even the title could be accurate, or ironic.
NedL - Smokey - Dreamlike, and subtly suggestive too.
bergytone - muscle..lots of muscle - Nicely framed, and I can almost hear the growl.
TheToadMen - An Off Center Series-#s 1 through 7 - Im going to go out on a limb here and deal with this entire series as individual parts of a single whole. Individually, each image is interesting, but the series together is stronger than the sum of its parts. Together, they suggest the movement and energy and diversity of the city of Utrecht, The Netherlands in a way that normal, non-panoramic images seem to do. They sweep.
If I had to pick one image to stand alone, it would be number 3. The shop window suggests a turning of the corner in life.
TheToadMen - Self-panorama portrait #1 - Im not sure how well this photo deals with the theme, but I like it a lot.
TheToadMen - Couple-panorama Portrait #2 - This portrait does deal with the theme well, because it does a better than average job of suggesting a relationship between the subjects of the portrait, and their environment. I would suggest experimenting further with this.
Next, the 6 images posted only to the thread.
Member - Title - Comment
peter k. - Let it Go - An evocative image, that suggests childhood, and summers and games.
peter k. - Light at the end of the Tunnel - A strong image that suggests many things: escape, warmth from cold, Gollum
peter k. - On To The Reception - There is so much here that is in accord with the theme. It suggests an important event - either a wedding, or an anointment, or even a ritual sacrifice, or ???, but we wonder what happened. Has the celebration moved on, leaving the scene lonely and forgotten, or did it never happen? The image itself is visually appealing, and the mystery seems real.
peter k. - FOCUS - One - This is confusing and mysterious and beautiful all in one. It suggests a faerie world to me.
peter k. - FOCUS - Two - I like this one too, but it isnt as mysterious, so it is less suggestive and more literal. It looks really good though.
TheFlyingCamera - Bridge - This is striking visually, and has great mysterious tension. It is all about a suggestion - questions and only hints of answers.
After reviewing all the above, it was a difficult task indeed to come to a decision, but here is the result.
Second runner up (third place) goes to
barbara ann for Netting. It is subtle, it hints, and it looks great.
First runner up (second place) goes to
TheFlyingCamera for Bridge. Visually it is almost the opposite of barbara anns photograph, because it is dark and almost foreboding.
AND
The winner" (first place) goes to
peter k. for On to the Reception. The mystery is strong, and the image is striking. And there is always at least something suggestive about weddings.
This of course brings rise to the question we started with. peter k. is not a subscriber. I will send him a private message to ask him if he wishes to either:
1) subscribe himself;
2) accept the generosity of those who have offered to buy a six month subscription for him; or
3) accept the winner status as awarded, but defer to TheFlyingCamera for the purpose of choosing the next theme and judging the results.
Thanks again everyone.
