Came across this really thought provoking and inspiring post on 500px today – I’ll certainly be trying this out as an approach in future and will share some of my attempts …

Always shoot at top quality…

You never know where your photo will end up. A few weeks back, I got a call one day from Carmel Mannion at Jump The Moon PR asking me if I had a photo of the name plaque on Pieta House. I did actually have such a photo, and vaguely remembered shooting the front of the Centre in Lucan several years back. I was sitting at my computer, and while I was being told the reason for the request, was firing up Lightroom and using Pieta House as a keyword, managed to locate the shots.

Now they were taken 4 years ago, and for no more than general photos for possible use in internal website publicity. But I always shoot in RAW and at the highest possible resolution, because of just this type of situation. The requirement was for a hi resolution image suitable for use on the iTunes icon for the Aslan single in aid of Pieta House, “Catch Your Fall”. I pulled a few together – I had actually shot a set of exposure bracketed images, and the one below was selected – great to be able to be a tiny part of this great awareness and fundraiser for a charity I have supported for many years now.

You can download the single from iTunes at https://itunes.apple.com/ie/album/catch-your-fall/id633956107?i=633956108 please do, it's only €1.29.

Pieta House is Ireland's only completely free professional service aimed at the prevention of suicide and self-harm. For more details check out www.pieta.ie or call 01 601 0000.

 

Taking 80 year old photos with an iPhone

Old negatives brought to life!

As a long time photographer, its always fascinating to try a new technique for creating images, and coming across such opportunities can get rarer and rarer. I had a fascinating evening figuring out a little photographic problem the other night. As part of The Gathering celebrations in Ireland this year, many towns and villages are hosting reunions, and Drumgowna in Co Leitrim is basing theirs around the old school – see their website at http://www.drumgownaschool.com .

A friend of ours who is living in the area came across a lovely find recently – an old shoebox full of old negatives. They looked really old, and were obviously well before 35mm film. I did some research and the film looks to be 116 film, which is 6.5 x 11cms and introduced in 1899 by Eastmas Kodak. As with any negative, holding them up to the light gives an idea of the image, but it's always difficult to really get a feel for the real image until it's been converted into a positive. So Reg arrived for the evening with the envelope of negatives and the question – could I turn them into photos she could see, and maybe then use as part of the village celebrations?

My first thought was that I might be able to use my new photo printer/scanner, but scanning the negatives just gave me very dark versions of the negative, so that wasn't going to work. then my wife reminded me that we had seen an app previously which claimed to be able to convert negatives, so I went on-line and soon hit on HelloPhoto. On visiting the Apple App Store I found that I already had the app, just not installed on my current iPad, but that only a took a few seconds to download. Reading the help screen I saw that this needed the app installed on my iPhone as well, so I did that, and was ready to begin.

Negive on iPad mini kit by HelloPhoto

My iPad mini was used as a light box – basically a light under the negative to make it stand out clear and sharp. HelloPhoto lets you set all kinds of screen sizes, colours and intensities, but I just set it to the maximum brightness (5500k) and full screen, then put the negative on the screen.

The next step was to fire up the app on my iPhone, and set it to photo taking mode in the app. Holding the phone about 12 cms above the iPad and negative, the iPhone then took a photo of the negative lit from below by the iPad, and then as if by magic, turned the negative into a real photo.

The buzz I got the first time I did this was something else! I never did film developing, only coming into serious photography with the advent of digital cameras, so the transformation and bringing to life of these old pieces of thin celluloid to images of real people from long ago was like magic.

It took a few extra steps to get to a workable process. I found that the negatives were not lying flat on the iPad screen, and after a few seconds the heat of the screen would make the negative curl up. I fixed this by finding a piece of card about the size of the iPad screen, then cutting a hole in it the size of the image on the negative – this could be placed carefully on the negative and held it down on the iPad screen with the card pressing down on the outer edges of the negative, just letting the image itself show through.

This had another benefit of reducing the upward glare of light, which was giving me an apple shaped reflection off the back of the iPhone. I got rid of this by cutting out a bit of paper the size of the back of the iPhone and sticky taping this onto the back of my phone, so there was no reflection.

Finally I had a bulletproof process, and the 30 or so negatives took about 15 minutes to turn into photos again – the first time these images had seen the light of day for over 80 years. I've reproduced a few of them below, and I think that the folks over in Drumgowna are going to use them as part of their exhibition for the School Reunion – check their website for more details of their events.

Cat and Mouse

You don't scare meMouse 1Mouse 2Mouse 3Hmmmm - dinner...

Cat and Mouse, a set on Flickr.

Round at Mary’s this weekend and the cat found a little mouse in the yard. Plucky little thing – the mouse that is – and I spent a few minutes trying for a good shot of the two of them, with the first one in the set I think the best – the mouse was actually jumping up at the cat trying to scare it away!

I’m sorry to report that the story didn’t end well for the mouse, poor little chap…

Getting the shot – Powerscourt Lion

Powerscourt Lion – Joe Houghton Photography
Nikon D300, Tokina 12-24mm lens set at 12mm, F13, 1/500th sec, ISO 250

We had a great photo walk recently shooting the magnificent Powerscourt Gardens in Co. Wicklow, and for this post, I want to take a look at the process I went through to produce the shot shown here, because the original out of the camera looked VERY different.  Read on to find out more…

Composition.  Before you take a shot, you should be considering the elements in the scene you are facing.  Around the house at Powerscourt there are numerous statues, urns and pots of beautiful flowers, and the lions on their plinths caught my eye.  Big scenes often benefit from something in the foreground to start the viewer’s journey through your image, and such foreground interest should typically be located on one of the thirds lines.  My lion and the vertical of the plinth below his head is a little further left, but this was necessary to compose the house behind as well.

Verticals.  Especially with a wide angle lens, it can be difficult to maintain straight vertical lines.  The key ones here are on the plinth, so I made sure to keep them vertical – means the right hand side of the house tilts a bit, which I could adjust using perspective correction in Photoshop, but I didn’t this time.

Depth of Field.  Another creative decision for any shot is how much of it you want in focus.  For this shot I wanted everything from the foreground to the house at the back nice and sharp, so I used A (Aperture Priority) mode on my camera, and selected F13 to give me this.  Selecting that on the bright day we had gave me a shutter speed of 1/500th sec – plenty fast enough for a sharp shot handheld.  If you are using scene modes on your camera, set your scene to the mountains icon to get a wide depth of field where most of the shot is in focus from front to back.

Focus.  The general rule with large depth of field shots is to focus about 1/3 of the way into the scene.  Difficult in this case, so I focussed on the lion’s face and trusted the F13 setting to give me enough focus all the way back to the house.

Polarising filter.  I’ve written about this indispensable piece of kit in an earlier post, but on a lovely blue sky day it really comes into play, enabling you to darken the sky giving real “pop” to the clouds, lion and the house.

Check Your Histogram.  A lot of people, especially beginners, shy away when they run into the histogram display on their camera, but it’s a very simply and VERY powerful information source which you should at least understand the basics of interpreting.  Basically all you need to know is that the lines towards the left edge of the window are showing dark areas of your shot, whereas lines over to the right show that there are whiter areas in your shot.  If the lines touch the left edge, you’re underexposed, losing detail in the darkness, and if the lines hit the right hand edge, you’re overexposed and blowing out your highlights, losing detail and whiting out areas of your shot.

On the left here is the histogram for the original shot in the camera – quite dark with no bright areas or white in it.  After I’d made the post-processing adjustments I describe below, the final image’s histogram looks like the one here on the right – you can see the tones are much better spread and with no “clipping” on the right or the left.

So what did I do to change my original shot into the final one?  By messing about in Lightroom for a few minutes – adjustments to an original image to change it is known as…

Post-processing

Here are the shots before and after processing, so you can see how different they look.

I deliberately chose a really dark shot for this post to show just what a bit of post-processing can do to an image, especially if you’ve shot in RAW.  As long as you don’t over-expose on a bright day, you can pretty much rescue any dark shot as there is much more data stored in the darker end of the image than the bright.  My programme of choice is Adobe Lightroom, but the same principles apply whether you use free software like Picasa from Google (a great choice for those just starting), Adobe Photoshop Elements, or even the big daddy of them all – Adobe Photoshop.


So everything up to now has been done in-camera, but it was a very bright day, which makes capturing a shot with high contrast like this quite difficult.  I was also using my wide angle Tokina 12-24mm lens, and with the polarising filter on the front you can see some vignetting in the corners where the filter is showing at the extreme wide angle setting of 12mm.

Lightroom processing history for the final image

So, reading from the bottom up (because that’s how Lightroom records the changes), here’s what I did to the image.  Note – all changes to images in Lightroom are recorded in a separate file from the original RAW image, which means you can always undo them.  Hovering your mouse over each line in the History shows the image as it looked at that point in the editing process.

Exposure was my first adjustment – and the original was so dark that I needed to increase by +2.26 stops – that’s quite a lot but you have up to 5 stops either side to play with when shooting in RAW, so as long as the detail is there and you didn’t hit the edge of the histogram, you can bring all the detail back.

Highlights is an adjustment which only affects the very brightest areas of your image, and after bumping up the overall exposure this then added even more punch to the clouds and the roof of the main house, also accentuating the relative darkness of the blue sky behind.

Black Clipping affects the other end of the spectrum, and the minus 13 adjustment here just made the blacks a little bit darker.  After doing this I pushed the Highlights even brighter to punch the relative contrast even more, then a very small push to overall Contrast brought things to where I wanted them, with detail retained in the sky but also in the stone of the plinth and the grass in the plinth shadow.

Clarity was my final tonal adjustment – it’s a wonderful setting in Lightroom which punches up the micro-contrast across the whole shot, like sharpening but without the nasty edges which that can leave.

That just left a bit of cropping to lose the vignetting from the filter, moving the image around a little to keep a sliver of grass down the left hand edge, and I was done.

Getting the shot – Dublin Quays Panorama on iPhone

I’m often asked – how did you get that shot, so this is the first post in a series called “Getting the shot” where I will post a photo and then discuss the process of seeing, taking and processing it to a final image. I welcome comments and critique, so feel free to have your say!

Dublin Quays panorama – cropped version processed with SnapSeed

This image was taken on a night photo walk around Dublin’s Bord Gais Theatre and the south side of Dublin Quays earlier this week, and for this shot, rather than using my Nikon DSLR, I thought I would see what I could get using my iPhone 4.  Low light poses a problem for the tiny lens and sensor on phone cameras in terms of getting quite grainy looking images, but nothing ventured…

Pre-visualization is a photographic technique which basically means having an idea in your mind’s eye of what you want your final image to look like.  With a panorama shot, especially such a wide one as this, the image you end up with is actually quite different from any single view your eyes see, as to capture the 7 shots which make up this 1 image I had to rotate from left to right 180°.  I wanted to get some sky, the buildings and also almost an equal depth of reflections, so for this set of shots I turned the iPhone portrait mode – so the individual shots were taller than wide.

The app I used for this composition is AutoStitch, but there are other good iPhone panorama apps which will do a similar job – Dermendar is one I reviewed here, and Microsoft have their PhotoSynth app which is also very good.

The reason I used AutoStitch is that it allows you to set quite high resolution settings for both the images, the blending process and the final output panorama – it can save a single panorama shot of up to 18Mb which makes for quite a large image.  As you start to take your shots, and move round to the next position, you can see a ghostly image of the edge of your last shot which makes lining things up much easier.

Tip – always go into the settings of any photo app and set everything to the highest/best possible settings – anything less and you are really compromising the already limited abilities of the camera lens & sensor to deliver clean images.  

There are many tripod mounts available for iPhones these days, but for these shots I was just standing very still and hand-holding – a bit crazy at 9pm with the light going fast, but hey – it was an experiment to see what I could get.  Gotta have fun with your photography, and trying out stuff to see if it might work is all part of that.

So I took my 7 shots, then pressed the button to set AutoStitch to aligning and stitching the initial panorama together.  Once this is done (which took about 10 minutes with the top quality settings and 7 shots to process) you end up with a raggedy looking wide panorama which you then need to crop to get a clean rectangle.  AutoStitch automatically offers you the biggest crop area it can and generally I just accept that to lose the raggedy bits.  Here’s the shot at this point of my process – note the quaysides showing at both edges of the shot showing that this is a full 180° panorama.

Dublin Quays panorama – initial version before additional cropping

Now, for many shots this is job done, but being an inveterate tinkerer I like to run photos through some post-processing just to see if things might be improved at all.  This can of course be done on the iPhone screen, but I will generally wait until my photos have synced onto my iPad at home and then do editing on the much bigger iPad screen.  My app of choice these days for most photo editing on the iPad is SnapSeed by Nik Software – it is simply superb, and quite the most powerful and easy to use photo editor I have yet tried – and I’ve tried pretty much everything out there!  In the image version below I’ve applied a bit of selective brightening to the very dark building 2nd in from the right, and also applied a touch of “structure” from the detail menu in SnapSeed, which also brightened the sky up a touch.

I actually quite like the initial version’s composition as I think that the composition lines of the quayside at each edge of the shot work in taking your eye out to the other side of the river and the lit buildings.  Penny, my wife suggested I try a crop to lose the quaysides and focus more on the lit buildings and reflections, which is shown below.

Which do you like better, and why? – please do post a comment and let me know :).
