Camera Skills - post production techniques

Post by Micheál » Thu Jan 03, 2013 10:22 pm

Notice I'm not going to mention the "P" word since there are lots of other image manipulating tools out there.
Whilst I don't intend to stick a whole lot on here, I think it best to keep it in its own topic - ok?

Here how to correct buildings that have become distorted by a wide-angle lens (I'll use generic description common to many popular tools - not the terminology of any particular software). Remember this? The Town Hall all leaning in?

1. Dont crop before you correct - you'll be glad to have 'spare material" at the sides.
2. Straighten the image so that the centre of the building is running true vertical - dont worry where the rest goes. (If your camera was dead level, you wont even need to carry out this step)
3. Increase the size of your workspace (not the image, but the space it is displayed on) so you have about 30% "white space" extra on each side
4. Activate a grid so a sum copy is overlaid on the image (This is just to help you allign)
5. Ignoring the added space (Step 3), "select" your original image and convert that "selection" into an "object"
6. Leaving the bottom corners alone - stretch the top corners out into their neighbouring white space as far as it takes to align the building with the vertical grid lines. Be careful to stretch both side equally
7. de-activate the grid - you'll end up with something like this -

8. Crop the image to a standard proportion e.g 8x6, 6x4, 6x6 so that all of the white space is dropped.

The real lesson here is to plan ahead before you even take the darn picture. If you intend to apply this process, be sure to take a wider shot than you really need.

As you can see, in my shot, when I crop away all the white space , I'll end up losing the Church Steeple ( which in this case, adds a nice context to the main subject). If I had brought in more of Marine Road, I could have avoided clipping St Michaels in this way.

There are lots of great software tools out there. Most PCs come with one already on board.
I never stick to a single tool - I use whatever software I think is best/easist for whatever I happen to be doing. The ones I favour most are
Picasa - red eye removal, straightening, cropping, uploading
Flickr - uploading, providing links to DunLaoghaire County
Photoshop Elements - mostly for downsizing for on-line display & almost everything else - there's a first class, free on-line version here http://photoshoponlinefree.com/
Corel Photopaint - a very old version - but superb for complex editing, manipulation etc.
Colour Thief - not quite for image editing, more for analysing colour patterns to be copied when theming associated web pages etc. http://lokeshdhakar.com/projects/color-thief/

Wonderful how dynamic back-lighting can give a whole new look to the Town Hall.
Pity the two clocks arent in sync. A minute's a long time when you're running to catch the last DART. :) :)

I'm amazed that none of you questioned that photo I posted. A little Photoshop on the green and red,and cloned over a building on the right.

It's Big Ben folks! :D
