Exercise 9 Scene Dynamic Range.

This first image was taken indoors late in the afternoon.  Measuring with the camera meter set to spot mode I measured a dynamic range of 8 stops from the brightest area to the darkest.  The histogram shows that most of the image is on the shadow end of the histogram and I am a little surprised at how little of the histogram is taken up by the window area off the scene.  The dynamic range is quite high and the histogram shows that.  If I zoom in on the subject the shadows and midtones are full of noise.  This is not an ideal situation for the perfect exposure and I think here you would be well advised to take it a different way.

This second photo is a low contrast or low dynamic range image.  While the histogram shows a full range of tones I would say than most of them are on the left and in the centre of the histogram.  I measure the scene dynamic range as about 2 stops.  I thought that the darkest part of the image would have been the book cover but it’s not, it’s the right hand top corner in shadow.

The next scene has approximately 6 stops in the difference between the darkest and the brightest areas of the images.  I would say that this histogram is on the high side in terms of dynamic range.  I guessed and measured the darkest area to be on the left under the tree and the brightest is on the right near the centre in the clouds but actually I think the brightest area is near the top right hand edge so in fact this could be nearer to 7 or 8 stops.

This image is a low contrast image.  The difference between the brightest and the darkest areas of the photo is 2 stops.

A high dynamic range.  I measure the difference between the highlights and the shadows as 10 stops,

HOW I GOT HERE Of course, I wasn’t always a full time photographer. I spent a lot of time in the corporate world. I had a job which paid well, but just didn’t excite me. I remember the day when I had had enough. Enough of selling myself short, enough of dreaming too small, enough of doing what others expected of me. I had put away my dreams and told myself I would get back to them later, but somehow there always seemed to be something else that had to get done first. A friend of mine had recommended I take the NLP Business Practitioners course, and although I was really busy, I decided to do it. During that time, I began to imagine the different paths my life could take from here. While I had a hazy picture of what this other life might look like, I had a clear picture of where my current life was going if I didn’t change. It was a scary moment, a bit like standing on the edge of a cliff deciding whether to jump into the great unknown or stay on the cliff, safe but trapped. I jumped. The transition to the life I wanted was challenging The transition to the life I wanted was challenging but I would never go back. After that day I resolved to do what I love, to follow my bliss.  Picking up a camera after several years away, I found that many things had changed, the digital age had arrived. In the intervening years, I was too busy to pay any attention to my photography, and occasionally when I took something I really liked, I would think “how do some photographs seem so captivating and others leave me completely cold?” I knew this is what I was meant to do Somehow though, I knew this is what I was meant to do. I dedicated myself to learning everything I could about being a photographer. I took many, many courses and I read every book I could get my hands on, I still do. Since then, I have dedicated myself to helping other creative photographers achieve the results they want. And what a journey it has been. Last year I qualified as a coach. My main area of interest is creativity and helping others to express their vision. WHAT I BELIEVE Along the way, I’ve learnt that there are no rules. Experiment, explore, play. My advice is to make your art from your heart, not for the praise or the money.  Lighten up. It’s important to take your photography seriously, but it's a mistake to take yourself too seriously. Finally, you get what you want when you never, ever give up so enjoy every minute of it and just do it!
