The Windmill!

By Jas2
This is a picture of a windmill on a lovely sunny evening 2 days back! I have 2 versions - the lead image with lens distortion corrected manually, the version 1 is the original without lens distortion correction. Which of the 2 is more dynamic ? Is it always essential to correct the wide angle lens distortion?

The original all the way for me! I really enjoy wide angle lens distortion, although it isn't to everyone's taste. It's about how other sorts of lenses see - the human eye is just one possibility of many.

The 'corrected' version looks awkward to me, and it also makes the tower look shorter and stubbier, whereas the original is dynamic and commanding. It conveys height. The original also creates a much stronger relationship between the tow buildings, leaning towards each other.

I would like to see a bit more space at the top and less at the bottom. And get rid of that little blob peeping in on the right side of the frame, plus there's a dust bunny in the sky at the top of the frame... Minor tweaks, mod to follow.

Excellent work, Jas! Voteable.

I'd either crop the original a little, to tighten the composition, or straighten a little bit less than in the lead. You need to leave just a tiny bit of leaning-in vertical to make a close viewpoint with a wideangle credible: the eyes expect to see a bit of convergence.

I like the corrected version all straight and very very nice, why not?

This is perspective distortion, not lens distortion.
Rather, to qualify that, the perspective appears distorted because you're very close to the subject. The ratio of the distance of your position to the base of the building to that of your position to the top is large.
If you were fifty metres back that ratio would be much smaller. So the lens is recording that 'correctly'.
So do our eyes but the processing engine behind them makes its own corrections based on what it knows about the shape of buildings.

The question then is how much to correct.
'Normal' converging verticals in buildings can look rather extreme when 'fully corrected', so something around 90-95% oftn looks more acceptable. We accept some tapering as we look up. I came across this on a Capture One webinar quite a number of years ago. Of coiurse, this will depend too on the nature of the building and the specific viewpoint.

I don't mind this type of distortion in some cases but when the subject is a building such as this I like to take some action. For example, in your original image the building does have a very pronounced lean (that would fail building regs I'm sure!).

So my mod goes someway to avoid that. I also take it that the building is narrower at the top in any case so that makes fine correction a bit of guesswork so I didn't spend too long trying to work something out exactly.
Purely correcting for convergence will produce a squat look so I increased Canvas Size and stretched the image upwards, otherwise the tip of the sail would get lost.

Bcause of that super deep blue sky I couldn't resist a mono conversion!

The distortion is extreme, so I would correct it at least partially.

First though get the centre line vertical, its needs some rotation, and then correct.

It benefits with the white balance being a little warmer.

Mod 6 shows the result.

As you can see, Jas, opinions differ: some want to see a fully-corrected (or nearly so) image, others like the occasional bit of distortion... So it's partly a matter of personal taste, like so many things in photography. Personal taste matters, though, and that's an important lesson in itself.

Another approach - I went back to my first mod (mod 2 here), used Perspective adjustment to reduce the extreme effect in the original, while leaving plenty of evidence of use of ide angle. (Why use wide angle for architecture if you don't want this effect??) But then I added canvas space at the top and used Free Transform to stretch the image up. This brings back the height of the windmill.

Just a suggestion.

This subject has always fascinated me, Jas, and I have read all of the above comments with interest.

Perspective can impact the appearance of straight lines, and we are always looking for good straight lines in our photography, or at least one or two. But any lines in an image will appear to converge the farther away from the viewer's eye they are or as they approach the horizon in the distance.

Buildings generally have straight lines that can draw attention to anything being a little off. Buildings are particularly affected, and will look as though they are thinner at the top when you shoot from a low viewpoint, also a person's nose looks bigger when a wide angle is used close up, or how about a road disappearing into the distance?
All these are results of perspective distortion and all affected by the angle of view and focusing point.

You will probably have heard the term "converging verticals". To reduce converging verticals when shooting with a wide-angle, you could try to find a shooting position that has some height. Not always possible.
But you can try stepping back from the building and see what difference that makes.
Try to choose your position carefully. You’ll find that unless you’re perfectly straight on and at a height that is even with the middle of the building, your vertical lines will taper towards the top.

Getting this right at the time of shooting isn't always possible.
In processing, to have an image like this looking natural, you won't need to completely straighten your verticals, and I find the 4th modification by Keith very satisfying. I also like Moira's idea of stretching the frame so that the windmill isn't looking too squat.

And, yes, this is called Perspective Distortion.

Hi Willie,

Just to clarify , when you say get the vertical straight , does that mean the Right edge of the windmill as that leans it further into the other building?
Sorry for my nativity!!

Hi all
Many thanks for all your comments- the bottom line seems to be - correct a bit of perspective but not completely!
I am uploading another photograph - slightly better perspective I feel and it more wisps of clouds in the background!

Sorry John and Moira- I have left the daffodils- my reasoning- it adds a bit of mood , informs about time of year , frames the buildings beautifully and acts as a leading line into the shot!

I hope you understand why I prefer it !

Looking forward to your comments - as in this latest picture the windmill has a bit more height - I believe because I lay on the ground and shot skywards at the buildings!

Regards

Hi, Jas -

I like the new version - perhaps a good compromise between extremes.

For me, extreme distortion is fine: I own a Samyang 14mm lens for full frame precisely to exploit distortion with nudes, and it's fun with architecture, as well. Really, a matter of personal taste.

Daffodils and adding information: I definitely understand the desire to give full information, and that is often a good thing. On the other hand, sometimes a picture is about the look and the mood, and to that end it's more important to exclude things than to include them. whatriveristhis is an expert at doing this in his images, and I've blogged about the idea in the past, HERE.

I like your latest version, it conveys height.

The daffodils are fine, I left a good strip of them in my crop. It's just a matter of balancing space below the subject with space above. You've allowed extra space at the top, which works.

Hi John,
Many thanks for the link..lovely blog ..love the comparison between a painter and a photographer as eloquently put by Alan!

Mnay thanks Moira for your advise and encouragement!
Just goes to say once you find an interesting subject jus click as many as possible to as many possibilities!
