Technical controls












the aperture task

this task required us to set are cameras to AV this is aperture priorate this allows to change the aperture but the camera changes the shutter speed Changing we where very simple set the task of taking two different photos displaying different depth of fields one with a large depth of field and one with a short depth of field using the Russian dolls as models  i came up with 


small aperture value




by increasing the aperture value to F/22  we decreased the size of the lens which decreased the amount of light aloud in which intern increases the depth of field which means everything is in focus. this means that the iso we then changed the iso to 100 but we found it was too dark so we set it to 200 because we where taking the photo inside but because we were  which  abled us  to capture a shot where all the focus  is on the  closet Russian

large apperture 





by decreasing the aperture value to F/2.8  we increased  the size of the lens opening  which increases the amount of light aloud in which intern decreases the depth of field which means only part of the picture is in focus. this means that the iso will then be lowered.




the aperture is set at 5.6 which is still quite a wide opening which is why the  image has a shallow depth of field the iso was set at 500 which is fairly light sensitive but not as high as it would need to be if the aperture was set at 22 




with the aperture set at 16 which is a relatively small aperture opening because of this there is greater depth of field as you will be able to see the iso would have to be increased to 1250 as apposed to the iso setting of 500 when the aperture was set at 5.6.







shutter speed task


we where set the task of taking different photos changing shutter speed we set the camera to TV this stands for  shutter priority  this means everything is automatic except the shutter speed this allowed us to mess about with different shutter speeds with out the photos coming out to bright because of the increased time that the shutter is open for so the camera changes the iso to counter the extra light movement looks such as having a faster shutter speed creates a more sharp image where a slow shutter speed allows more light in and any movement blurs. 




for this photo i was set the task of  creating a sharp moving image so I set the shutter speed to a  fast shutter speed of 1/50 which allowed me to capture this   sharp image this is good for sport photos the downside to fast shutter speed is there is little light a loud in so the iso is increased by the camera to counter this effect. some photos still came out dark.

when the shutter speed is to low to much light will enter and this will cause  a white photo as shown  we had to lower the iso to compensate for the increased amount of light .





in this photo i set the task of capturing a photo which had a blurred movement effect i did this by setting the shutter speed to 1/8 which is a  faster shutter speed then the first photo but slower then the photo above the slow shutter speed allows a lot of light in but also allows us to capture movement in a different way giving it the  blurred effect 






i set the shutter speed for this photo at 1/40 which is a slow shutter speed which allows a lot of light into the photo the aperture because it was set on tv was automated so it compensated for the extra light by reducing the size of the aperture.the increased shutter speed means that the photo blurs  




i set the shutter speed for this photo at 1/32 which is a slow shutter speed which allows a lot of light into the photo the aperture because it was set on tv was automated so it compensated for the extra light by reducing the size of the aperture.the increased shutter speed means that the photo blurs  








white balance 

in this photo shoot we where set the task of creating a customer white balance photo you'd use this feature to  remove unrealistic color casts, so that objects which appear white in person are rendered white in your photo. Proper camera white balance has to take into account the "color temperature" of a light source, which refers to the relative warmth or coolness of white light.  and can create unsightly blue, orange, or even green color casts. Understanding digital white balance can help you avoid these color casts, thereby improving your photos under a wider range of lighting conditions.you would set white balance by  

Position the card
 position a piece of white paper so that it is in the same lighting as your subject.  place the paper where your subject will be, and make sure that it is facing where you are going to be shooting from.
Shoot the card
 fill the frame with the paper and take a picture of it from the same direction as you will be taking your main shot. The exposure of this reference image isn’t critical, as long as the picture isn’t completely over- or under-exposed. You need to switch to manual focus.



Delve into the menu
you need to navigate to your camera’s  menu and find the list of white balance settings. you then simply select Custom White Balance from the list of options that appears.







Set the white balance
Select the picture of the paper to set this as the white balance reference image. On press OK twice to set the white balance. then switch automatic back then  take your photo.











a few discussion notes about the colour temperature.......  


Auto white balance 
this tries to get the picture as close as possible to the colours that your eyes are seeing 

daylight/cloudy/sun/shade 
if you set the setting on daylight you will tend to get an orange look on your picture because its not taking into account the tungsten light 





Still Life Images

we were asked to arrange a number of objects on the table and organise the lighting for a dramtic still life image. the objective of this task was try out a range of camera  settings and composition arrangements until you are happy with the final look



I set the aperture to f/4 when you applied this camera setting a lot of light is allowed through the lens and as a result this image has a shallow depth of field and the background starts to become a little blurred if i was to take this photo again i would use a lower aperture maybe 2.8..I set the shutter speed at 1/100 which is a slow shutter speed which allows a lot of light in to the lens and it also means i needed to use a tripod to remove any shacking Iset the Iso to 3200 to compensate for the large aperture and large amount of light

I set the aperture to f/5.6 when you applied this camera setting a lot of light is allowed through the lens and as a result this image has a shallow depth of field and the background starts to become a little blurred if i was to take this photo again i would use a lower aperture maybe 2.8..I set the shutter speed at 1/100 which is a slow shutter speed which allows a lot of light in to the lens and it also means i needed to use a tripod to remove any shacking Iset the Iso to 3200 to compensate for the large aperture and large amount of light






I set the aperture to f/4.5 when you applied this camera setting a lot of light is allowed through the lens and as a result this image has a shallow depth of field and the background starts to become a little blurred if i was to take this photo again i would use a lower aperture maybe 2.8..I set the shutter speed at 1/100 which is a slow shutter speed which allows a lot of light in to the lens and it also means i needed to use a tripod to remove any shacking Iset the Iso to 3200 to compensate for the large aperture and large amount of light





















I set the aperture to f/3.5when you applied this camera setting a lot of light is allowed through the lens and as a result this image has a shallow depth of field and the background starts to become a little blurred if i was to take this photo again i would use a lower aperture maybe 2.8..I set the shutter speed at 1/100 which is a slow shutter speed which allows a lot of light in to the lens and it also means i needed to use a tripod to remove any shacking Iset the Iso to 1000 to compensate for the large aperture and large amount of light










I set the aperture to f/3.5 when you applied this camera setting a lot of light is allowed through the lens and as a result this image has a shallow depth of field and the background starts to become a little blurred but the decanter top is still in focus which is the point of interest ..I set the shutter speed at 1/100 which is a slow shutter speed which allows a lot of light in to the lens and it also means i needed to use a tripod to remove any shacking but because i wanted a high angle shot i had to go free hand but be very still.  Iset the Iso to 1000 to compensate for the large aperture and large amount of light












I set the aperture to f/2.0 when you applied this camera setting a lot of light is allowed through the lens and as a result this image has a shallow depth of field and the background starts to become a  blurred but if i was to take this photo again i would use a larger aperture because this photo is to blurred is becoming out of focus ..I set the shutter speed at 1/32 which is a slow shutter speed which allows a lot of light in to the lens and it also means i needed to use a tripod to remove any shacking if i was taking the shot again i would use a faster shutter speed to reduce the amount of light let in .  I set the Iso to 200 to compensate for the large aperture and large amount of light









I set the aperture to f/2.0 when you applied this camera setting a lot of light is allowed through the lens and as a result this image has a shallow depth of field and the background starts to become a little blurred but the pumpkin  is still in focus which is the point of interest ..I set the shutter speed at 1/32 which is a slow shutter speed which allows a lot of light in to the lens and it also means i needed to use a tripod to remove any shacking .  Iset the Iso to 1000 to compensate for the large aperture and large amount of light
