I'm seeing mountains where only molehills exist. In any normal, standard editing challenge I can make an altered version of the base layer, say a darker version, and I can layer it and change the mode, say to darken, and I can MASK that layer to only apply the darkening where I want to. I don't see any issue in this flip 'n blend process at all, once we've flagged it to allow the unregistered superimpositions. In Extended editing, on the other hand, there's NOTHING you can't do basically, so it seems much more straightforward to loosen up Standard for the challenge than to limit Extended. Either way, it's a fun challenge. Don't get so hung up on details, legality, and all that hoo-hah. As long as you work from a single image you're gonna be fine, unless you do something so outrageous we haven't even thought of it, and maybe even then.

There's a time and a place for worrying about making sure everybody is parsing the rules the same way, but this isn't the time and this challenge isn't the place :-) Let chaos reign!

Seriously :-) Lighten up :-)

But... I'm already in, so...

I don't care. :D

Yes, but that goes back to the point that Jake raised in this, we actually modified the original image. Not sure what that filter is doing to create that effect if that does all erase and cloning and all to create then how can that be a valid and not if I do erase of a layer and merge the image to parent and then do flip-flops.

Every request for validation asks for a summary of the editing steps.

Personally, I think you can adjust your image however you want; what I don't think is legal is duplicating a layer, erasing/manipulating part of it, and THEN flipping it and blending it into the unmanipulated version -- to me that is like merging two different pictures.

But you can distort a layer first, copy it and flip it and blend it back in -- I've found using the Wave filter on an image and blending it back into itself often yields pleasing "organic" curves ...

There's nothing standard about this and nothing that can be verified from the original image unless we're required to submit the final image stack for investigation as well. IMO it should have been Expert with the flag that we can only use a single image that, prior to any flip/blend/twirl application meets all criteria for Standard editing.

That is unless this challenge requires that you not do the Mezzotint and Radial Blur steps typically found in the tutorials for this technique - something not stated in any way.


I agree. I can see why a challenge that starts off as Expert can't be changed to Standard somewhere along the way without causing real problems. However, I don't see that the reverse is true.

And no one is suggesting here that we can't edit the original photo in ways that would be acceptable under standard editing rules before we start to distort, right? I mean I cleaned stray leaves and branches out of one before I started flipping and bending and twirling. That's acceptable, correct?

It's pretty clear that nothing can keep some of us from spending insane amounts of time flipping and blending and twirling, but it would be really nice to be able to do so with the confidence that we could USE our favorite outcome in the challenge :)

And should we be unlucky enough to be among the top five (which at least five people must inevitably be), please tell me that we will not have to provide a step by step tutorial that would allow SC to exactly duplicate our result. Do you have ANY idea how much note taking that would involve??

The answer to this, or the fact that it has to be asked, kind of makes me wonder just why a challenge like this is "standard" to begin with, because after the first to steps of any tutorial for this technique the image has already been manipulated in ways that would violate Standard editing rules were you to simply enter that. Objects have essentially been "removed" (albeit not in a traditional sense) and certainly not replaced with what was already there.

So this begs the question, is it the original that cannot be changed, or is it the initial manipulation of the original? Or is it the first twist of the manipulation of the original?

To your question directly, I can apply an adjustment layer to a standard edit and effectively "erase" (as you say) how it is applied to one section of that layer. That's not illegal. So why would it be here?

What if I decide to warp, resize, or otherwise alter the perspective of one of the blended layers? It wouldn't necessarily be illegal in a standard edit but since it's not the same as every other layer in my stack is it now illegal here?

There's nothing standard about this and nothing that can be verified from the original image unless we're required to submit the final image stack for investigation as well. IMO it should have been Expert with the flag that we can only use a single image that, prior to any flip/blend/twirl application meets all criteria for Standard editing.

Probably not legal for standard editing.

As mentioned you can use any blending mode, and sometimes asymmetry may be the desired effect -- there's no requirement for the final image to be symmetrical. If you are using Photoshop try using Filter>Distort>Wave with some high numbers ...

I'll go fix that....

Nevermind, LOL. The challenge instructions are non=specific, I guess this refers to the instructions in the thread. Soldier on, flippers 'n blenders...

Agreed . Much more fun to play with the different blending modes.

The Instructions:
In PS I do the following: (Gimp probably has something similar)

These instructions are for PS CS3 but may very well work for other versions of PS and maybe for other software.

Open the image you want to edit and make sure the layers palette is visible.
Duplicate the background layer
From the edit menu, choose transform and select flip horizontal
Change the blending mode of the layer to difference.
From the layers menu, choose flatten

Duplicate the background layer
From the edit menu, choose transform and select flip vertical

Change the blending mode of the layer to difference.
From the layers menu, choose flatten
Duplicate the background layer
From the edit menu, choose transform and select rotate 90 degrees (CW or CCW doesn't matter)
Change the blending mode of the layer to difference.
From the layers menu, choose flatten

crop to square (not always)

As you can see from the banter in this thread, these are only a starting point. Change them up, experiment and have fun.

Depending on the image, you may need to make adjustments in between flips and/or at the end as it may end up quite dark.

I tend to do selective exposure adjustments at the end to bring out the amazing detail in the center of the final image. I do this in Lightroom.

I've got this in an action now (everything but the crop) so I can see what an image will produce rather quickly

I've discovered that the plainest images usually produce the best results.

If you can't operate on layers individually then the duplicate steps can be to duplicate the image (in a separate file) then paste it in as a new layer before blending.
