Diptych and Texture Q's - DPChallenge Forums

Two questions and not related (yet).

I'm guessing you can have a border around both images so it would seperate them? (I've been away a long time so humour me please).

If I use a texture in a challenge image does it have to cover the entire image or can I mask areas (talking about standard editing challenges)

Thanks in advance :)

Yes, you may run a border to separate the images in a diptych. And you may mask the texture as well.

Cool and thanks :)

Didn't we have a DQ on someone only using a texture on part of their image... only the sky or something?

Has the rule changed? Or am I mistaken?

Many (many) moons ago I seem to remember issues with textures but have never used them so didn't pay (enough) attention. I'm wanting to try them now and wouldn't want to break any rules.

The rule must have changed with The Big Rules Shakeup, because I remember that DQ.

I *think* what you're referring to is that someone called a shot of clouds a "texture" and applied it only to the sky. ANY time a texture becomes the dominant visual component you are going to have a problem because we start treating it as a composite image. Textures, by their nature, need to be subordinate elements.

Thank you, Bear.

can u use a prime lens and change the focus rather than zooming in this challenge..:)
as it's not technically changing the focal length ..
I googled it .. !! .. ;)

I'd have thought not as it stipulates 2 different focal lengths in the rules (if it's not a DQ it may well be seen as a DNMC by the voters?. Maybe use 2 primes? or 2 cameras even?

Your submitted image must comprise two shots of the same overall scene shot at different focal lengths. For this challenge, you MUST use two separate images and they MUST be presented as a diptych (side-by-side or one over the other). without any overlapping of the images.

As always, not following a flagged rule will get you disqualified.

Where did the focal length diptych challenge come from? I'm really sorry if I missed critiquing it, if it was ever in the challenge suggestions thread (was it? please link to thread if it was, thanks). Can someone kindly tell me where its merit lies and why it's being run this way? Seems like an exclusionary challenge with a dq'able rule like this should have some point to it? Thanks.

It's a very interesting, purely technique-driven challenge, IMO anyway. It's akin to an exercise we'd use when teaching photography classes, actually. The idea is to get people to recognize the differences that come about by zooming in on a subject vs widening up in a couple of different ways. One thing you can do, obviously, is set up and shoot a scene, say a landscape, with a WA lens then swap in a telephoto and explore different ways of expressing the same scene by including/excluding more of it. This approach you could do by cropping of course, but you get better quality using the full sensor. The other approach, and potentially the more fruitful one IMO, is to shoot a scene from a considerable distance with a telephoto lens, then hike straight towards it until you are very close and can just frame it up with your WA lens. How does the mood change?

Are there emotional overtones riding on the differences between flat-field vs dimensional rendering? Is the scene MORE or LESS expressive of its essence when shot panoramically vs when abstracted to a few details?

And, of course, the same analytical exploration can be applied to, say, portrait shots or still life compositions. These are decisions the thoughtful photographer must make every time s/he sets out with camera in hand and a specific goal in mind. So it's about working on one small but vital set of techniques, the relationship of focal length to framing and compression vs expansion in the visualized image.

As to its provenance, it was proposed by

Paul in an SC thread on challenge topics. (Yes, we have one of those too over in our little corner.)

Googled diptychs different focal lengths and came across this Link

Another interpretation might be to use Diptychs to tell a story. Some of these examples are really unique.

Does this mean you can have a border - plain - top, middle, and bottom in a vertical or both sides plus middle in a horizontal? Please advise quickly as time is getting away from us on this one :)

Don't agree because as written, challenge description allows submission of a 51mm and a 52mm pair, but not a diptych shot with a fixed lens camera. Below explanation might have been more impactful in the public thread beforehand.

I think it's a great exercise. I'm hoping I have time to shoot it tomorrow. I know I have a tendency to stick with a particular lens and pretty much the same focal length. I rarely dabble with wide angle at all. And thus I don't use it effectively.

'Far and close' mighta done it. Or for you, wide angle only.

When I read the title of the challenge my mind went directly to Antonioni's film of the 60s "Blow up"

"Thomas (David Hemmings) is a London photographer who spends his time photographing fashion models. But one day he thinks he may have photographed something far more sinister: a murder. After taking pictures in the park, Thomas is horrified to find an ambiguous image lurking on the edge of the frame, which could be a shadow, but looks like a gun."

I thought that this challenge could produce good stuff, after all we found a whole bestiary in a sweet potato or a blade of grass....but unfortunately I did not have time to stroll to find something similarly interesting.
Nevertheless, why not participate in any challenges if possible, to use the verb "challenge" to its extent.
