Shutter Speed Practice and Histograms the basics
Histogram
Histogram graph is an available preview setting usually used in photo editing post production images. However you can browse the histogram whilst taking photographs on the camera this can be used as a guide for whether the images you have taken are too underexposed and those that are too over exposed.
On light-room these are some examples of histograms graphs. You can see that there are 3 colours and maybe additional greys and whites, I would call these the tone colours. the three colours are Red Green Blue ( RGB for short). The graph itself is used to understand how exposed your photograph pixels are, if your graph is gathered to the far left it is most likely the photograph is under exposed [ seen in graph 1] . The far left side represents black and in correlation the far right is white, if the graph is crowded to the far right it may be too over exposed [ seen in graph 2] , the key to obtaining a balanced photograph is having a central histogram [seen in graph 3] because the Mid-tones are more accurate to the situations.
​
There may be instants when the pixels could have far too much information and they may become dead, this could mean you'll have a single pixel which is just red, or green, or blue. This could because the lighting is far too overexposed and could damage the image because its too much.

Using a lighter and a tri-pod i set the camera to 8" and moved the flame around myself to capture the light, this is possible with a slow shutter speed because any light that enters the shutter remains in the shutter until it shuts. I used a tripod so that I could get the background and foreground in focus any form of movement would blur the image which was not the result I was looking for, after all this was a practice to demonstration how using slow shutters can capture light.
This photograph with the 4 ladies was done using a fast shutter speed. 1/80s at f3.5 on a 35mm camera, this allowed me to capture a moment in time, In reflection I would most likely use a fast shutter speed however I am happy with the result because I had lined the 4 women together at an incredible moment, this documents how quick the camera shoots at so that the legs of the people are frozen,
in hindsight to improve this it need to be a quicker shutter speed so making it 1/200 might be successful or 1/250. 1/500 to get that pin sharp moment and using a tripod would benefit the photograph.

Train spotting was a successful practice, using a tripod and a moving train from a platform at a station. The moving train was quick and this shows that the train is moving because it has a motion blur, typically because the camera captures the position of the train and retains that information in the camera and creates a ghostly line effect seen below in the two images,
