Distortion, Pincushion and Barrel = Nerdy post

Hi,

Following up on a comment by Paul / Nick on distortion I wanted to add some photos but can't in the comments so hence fresh post.

Both pincushion and barrel distortion are caused by non liner magnification across the image. They are in the same effect but opposite.


Barrel is when the edge of the lens is weaker than the middle. This is the most common and normally seen on wide angle lenses. You often see the tops tall buildings leaning inwards and not vertical with the frame edge, this is barrel distortion.



Pincushion (all one word) is when the edge of the lens is stronger than the middle. this is normally from low end telephoto lenses and not as common these days.



What can you do about it ?
- Keep the image plane (film or sensor) parallel with the subject, however this is difficult if shooting "up" at a building. This evens the effect out rather than correct the problem is though. Paul did a good job this way in Doha.
- Tilt and shift lens, VERY expensive but these you can tilt the lens off the parallel so takes care of the above issue. Both effect are lesser with expensive lenses but not gone.
- Photoshop. You can correct both effect in photoshop but the part of the image is cropped off.

(Images are of Google, same image in multiple sites but think it's thanks to Wiki originally.)

p.s. Sorry for the nerdy post !

Cheers,
Richard B.

Reflections on Water

Well, here come my offerings for this month. As Richard so astutely pointed out, with clouds hanging low and pendulous with precipitation, there was going to be no shortage of the wet stuff lying around waiting to be photographed. I tried to avoid the obvious 'taxi plunging through puddle', because there's plenty of those circulating on the interwebs.


Gate
Nikon D70s
Sigma 50mm
F/2.8 1/45s

Tried to get some symmetry here, with the gate lights and their reflections in the puddle. The hosepipe also counts as 'water', partly because I liked the splash of contrasting colour and also because I wasn't about to clone it out. That treatment was reserved for the obtrusive red 'No Parking' sign on the wall opposite the gate.


Minaret
Nikon D70s
Nikkor 18-200 @ 112mm
F/16 1/60s

Having retrieved my camera from the car, I was heading back into the office with intent to take a particular shot that I had in mind. Whilst that shot never happened, I saw the minaret reflected in a puddle and liked the texture. I simply inverted the image.


Anchored
Nikon D70s
Nikkor 18-200 @ 170mm
F/5.6 1/250s

Dubai Boat Show offered plenty of opportunities for 'Water' as the subject matter. I tweaked up the red gelcoat using a mask so that the red would 'pop' without the water developing a reddish colour cast.


Bow
Nikon D70s
Nikkor 18-200 @ 29mm
F/4.2 1/20s
Auto ISO

More Boat Show. It got dark, and I knew from experience that tripods on floating boats and pontoons is a recipe for camera shake, even if some oaf doesn't kick it all into the oggin. So I used the trick of setting the film speed (on a DSLR - Hahaha!) to Auto so that I could hand-hold the camera. There's a little bit of cropping and cloning to get rid of distracting bright lights. Look at the symmetry of the boat in the water, and also note the metalwork at the waterline that just hints of Poseidon's trident.


Reflections
Nikon D70s
Nikkor 18-200 @ 38mm
F/4.8 1/10s
Auto ISO

Again, hand-held in the dark (don't you just love vibration-reduction lenses?) at the Boat Show. The whole frame is of a sexily lit speedboat, but I thought the coloured reflections were more interesting. The graininess is caused by the high 'film speed' and also the cropping.

I should also note that I wanted to freeze the ripples in the water, so long shutter speeds that would allow blurring were something I actively sought to avoid.

Water - Steven's efforts

I have a couple other ideas but just in case I don't get around to it here are a couple of water shots to keep you all going:

Lighthouse on the Rocks
f4.5 1/2000 ISO200


Washdown Area
(f8, HDR, ISO 200)

I know these two are fairly spurious links to water but what can I say, if it was straight forward it wouldn't be nearly as......as........shutterbug now would it.

The first is the lighthouse at Kiama and has water in the bottom corner.  The second is the showers on site at Sydney Airport in the "Aircraft Dump Bay" which is the lovely area where the airplane toilets are discharged into.  Imagine a GIANT public toilet and proportionally smelly.  This is one place you DON'T want to have a reason to use the emergency shower!!

Nick's weird take on water

I actually have another idea I want to try out for this month's homework, which I figure is actually the point of the whole exercise. However, I found myself shooting these the other day. The first is my vaguely customary B+W:
"what the hell is this?"
f2.8; 1/100; ISO1600; 24mm

Then I thought it looked better in colour, in a modern art kind of way. And less slimy, too:
"No seriously, what the hell is that?"
f3.2; 1/125; ISO1600; -1 step exposure; 40mm

The reflection of the light is intentionally placed where it is to contrast with the dark colours, but I feel it's a bit too bright. And the dark colours are not as dark on my laptop as on the back of my camera in bad light. I could gimp it, but I can't be bothered. Anyway, for all those who want to say I should lose the spot altogether, I couldn't get rid of it and still have the water showing up so clearly. So to speak :) And for the techies, the spot is a ceiling mounted 50W halogen.

Now, I also have a cool back-catalogue water photo which is on the other computer, so you'll have to wait for that, along with my intended homework exercise, until my next posting.

Minature / Small World - Richards Effort

Hi All,

Better late than never, so here is my attempt at last months "Miniature / Small world". Following Paul's non photoshop with water I thought I'd be brave and bare all! These are all straight out of camera, not even a watermark !



"Out the toy box"
16mm, 1/13sec, F5.6, Av
Manual Focus (measured)
Tripod (yes inside the box)
Off camera flash top right.



"Abseiling"
16mm, 1/5sec, F5.6, Av
Off camera flash top center, to help texture.



"Run"
50mm, f5.6, 2/5sec, Av
Total -2/3 ev.
Flash low left.



"Back Step"
50mm, f5.6, 2/5sec, Av
Total -1/3 ev.
Tripod
Flash high right -1ev.



"Long grass"
100mm Macro, f2.8, 2.5 sec, Av
Tripod
Flash top right



"Freedom"
50mm, f5.6, 25sec, Av, ISO 200.
(it was dark hence 25s & ISO200).
Tripod
Flash low right.


As always, comments, abuse and questions welcome.

Cheers,
Richard B.

WATER: Paul's first pass

I'll post more later this month, but here's a small taster from my back catalogue. No PhotoShopTM.

Goslings

Nikon F80
Nikkor 28-200
Scanned from a negative, so no EXIF data

Spring is here. This springtime shot of a Canada goose and her brood of goslings was taken in May 2001. Say, "Aaah." Located at Crofton Pumping Station, near the summit pound of the Kennet and Avon canal, I remember being distinctly cold and damp. The overcast skies are why the water is that foreboding gumetal grey. There was no heating in the boat, nor running water.


Reflections of Doha

Nikon F80
Nikkor 28-200
Scanned from a negative, so no EXIF data

At the time, 2001, this was called the Doha Marriott Gulf Hotel. It's now simply the Marriott. I was on the roof of one building, and happened to spot the reflection of the rig support vessels moored nearby.
