Exercise - Higher and Lower Senstivity

f/10 / 1/13 / ISO 200

f/10 / 1/20 / ISO 200

f/10 / 1/8 / ISO 250

f/10 / 1/13 / ISO 320

f/10 / 1/20 / ISO 400

f/10 / 1/8 / ISO 500

f/10 / 1/10 / ISO 640

f/5.0 / 1/200 / ISO 640

f/5.0 / 1/80 / ISO 800

f/5.0 / 1/320 / ISO 3200

f/7/.1 / 1/500 / ISO 3200

f/7.1 / 1/200 / ISO 3200

For this assignment I used my fish tank, the moving bubbles and few fish were fast subjects in relatively low light conditions. The change of ISO improved the amount of available light but the graineness especially once ISO 3200 was reached was noticeable. It is an option that I used to ignore but will start using more extensively.

Interesting Pics from other students

I have been looking at the forums on the OCA student website for assignment 4 and love the below pictures.

I will be looking for a similar type of subject for mine or possibly a model to pose.. not sure how efffective texture will be on a model though

Update

I had reasonably favourable comments for my assignment 2 and now working towards the third one which is due in Mid May. There are a lot of exercises on this one and one of them requires a whole day - Light throughout the Day..

Found an interesting article on the colour of light which is well worth a read and relating to this section.

Exercise - Measuring Exposure

Below are my images for the first exercise.

Dark photo aimed mainly at the ladybird head and the twig

Dark photo looking at a fountain mechanism

Light colours highlighed by the white flowers

Another light photo of a candle.

These are lighter and darker than a normal photo due to high amount of light colours or dark colours.

Above are five sets of photos all set at different exposures.
