Apertures and ISO control photos& Photoshop filters


I experimented with apertures first,changing the F.stop size that the light goes through to see the effect it would have on my photos. I set it to a thin depth of field first,so that the front of the image was just in focus (the clock) To achieve just the foreground in focus i used a aperture of F3.5 which gives a small depth of field. As you can see only the hand and clock are in focus the background remains blurry. I learned in dark settings the aperture must be large as the F.stop hole bus be bigger to let in a lot of light. In Lighter conditions the F.stop size would be smaller as it doesn't need to let in a lot of light,therefore outdoor weather would be best to use.
I then used an F.stop size of F11 to gain a medium depth of field,this image would be more in focus than a smaller F.stop but not completely in full focus.
I then used an F.stop size of F29 to gain full focus and a maximum depth of field. The whole image should be in focus by using a large f.stop size. 


I then experimented with ISO settings,these are the cells that react with light. The ISO effects the graininess or noise of pictures,it is used frequently by artist for a distorting effect. The higher the ISO the more noise the picture will have, I firstly used a ISO of 100,this is the slowest setting and should be used in good weather conditions (bright) as it is the slowest setting to react with light. The normal setting for an ISO is around 200. If in a dark place a much higher ISO will be needed,i used an exptreeme ISO and changed the settings to 3600 which is the highest and fastest setting. Im not sure if the photos were effective in displaying the grainy effect as the camera seemed to blur more than create noise. I continued to experiment and some of the photos have 'noise' but i was disappointed with the outcome.






The above appear more grainy,the picture also looks darker and less fresh,this is due to the extreme ISO setting of 3600.I think these two above were the best experimental outcomes of my ISO testing.


I then experimented on Photoshop using filter effects,this was very fun and added a unique creativity to my photos;
Firstly i experimented with the lense flare filter,adapting the size of the light flare and the intensity. I started of minimal and then experimented using a wider range of light streak expansion.

I then edited the contrast,brightness and saturation of the image which added colour to the filter and highlighted and emboldened the background. I think this adds a life and intensity to the photo which it didn't previously have.

I then experimented with motion blur filter and the intensity levels of it,the faster the blur the less of the image that became clear. There were many types of blur i experimented with,smart blur,shape blur,surface blur.

I then experimented with the difference clouds filter,which changed the colours of my images like a heat signal camera would. It was an interesting filter to use but i thought it looked childish and the negative colours were very unnatural.
