Exercise 1.1

These are photos taken a minute or two apart with the same camera set up (I used a tripod). The object of the exercise is to show how the histograms change even within a short period and these are caused by changes in the light. I used Picasa and the Snip tool from Windows(i e a screen shot).

The subject is a display stand for jewellery which I make occasionally .

My camera and lens are worth a mention. Pentax their manufacturer did not change the size of the hole for their lenses (k mount) when they switched from film to digital so you can easily get cheap secondhand Pentax lenses and build up a respectable collection (ebay, Oxfam – I remember once I bought an old Pentax film camera plus lens just because I wanted the latter ). Sometimes the lens will work straightaway or you might have to adjust your camera which is relatively fiddly (see here from youtube https://www.youtube.com/watch?v=gUE0aQBy2D4 ). The lens I used was an Auto Chinon 50 mm prime (good for portraits – a prime lens being better than a zoom lens for sharpness).

Note below nice large photos! Finally figured it out when I read this http://malborkmalbork.blogspot.co.uk/2013/12/how-to-make-your-photos-larger-than.html . I am quite happy with 'extra large' though.
