That of course should be Flip/Blend/Twirl (II)

Anybody fancy a re-run of this one? Adding a bit of twirling into the mix.

It was a fun and slightly different challenge.

Use one original in as many layers as you like by flipping/rotating/warping/blending/twirling create a fascinating abstract
Extra: Single original source photo which needs to be included in the Photographer's comments.

Flip and Blend

Here's a thread from the side challenge back in 2014

archival would be fun, but not a deal breaker

A good challenge to do whilst still in Covid 19 lockdown.

Like it!

Oh dear, if I have any sort of "specialty area" this is probably it, likely making the result even more disappointing than usual. :-)

I've made some prints which incorporate this principle -- Each has eight variations made from the center image.

I believe there's an error in the challenge description. "As always in advanced, you may not use more than one source photo." should read "As always in standard, you may not use more than one source photo." Right?

True :-) I'll go fix it...

All fixed. Thanks for the sharp editor's eye :-)

Any time :)
09/14/2020 03:13:54 PM · #12
I've searched...

Is there a tutorial about how to do this, please?

Lydia - these are from one of the side challenge threads. be warned it's addictive.

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.


ETA: Link to original thread

Ha! Thanks bunches, Sarah!

I did one!

That was fun! :D

The instructions say to use difference blending mode, but I prefer some of the others. Difference can create too much detail. And with some blending modes one can create asymmetrical images.

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

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

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 ...

If this is going to be discussed more here, it might pay to get rid of the archival reference as the challenge is not archival.

Good idea :-)

How about if in one of the layer, I apply erase to remove some area? to make it look different. In here not from the original image but start from original, do bunch of flip and blend and during the time one of the layer apply erase to remove some portion.

Probably not legal for standard editing.

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.

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.
