Lens- Captures the light from the subject and brings it to a focus on  film or detector.

Exposure control- size o the aperture and the brightness of the scene controls the amount of light that enters the camera shutter controls the lenght of time that the light hits the recording surface.

Health and safety rules in the studio
  • No eating or drinking- could damage equipment
  • No running or fooling around - only small area and could damage equipment
  • No coats or bags on the floor- someone could trip up.
  • Dry hands before using electric's- could damage equipment or hurt yourself.
  • Use tong to handle photo paper- the chemicals could hurt you.
  • Dot mix the wet and dry side of the darkroom.
Darkroom health and safety
  • No eating or drinking -chemicals around

  • Beware of cables on the floor
  • flash heads get hot- handle with care
  • Dont look directly into the flash light
  • Be careful when using the paper blackgroun systems
  • Handle all equipment with care.


Process
  For our Pinhole photography, we had to bring in a box. I brought in a Pringles box to make my pinhole camera out of. Next we had to make sure that our boxes were not letting any light in. We had to paint the inside of our boxes so the light doesn’t reflect in my box. We then had to make a small square in our boxes to make the lens; we then covered up the square with foil and put a pin hole in it to create the lens. After this we had to measure the length of my of my which was 72mm we then had to divide that the 0.8 , this gave us our focal point which was F90. We needed to know this so we knew how long it would take to take a picture. For my box I had to keep it outside for 30 seconds and inside I had to leave it for 2 minutes.
Next we had to create a flap to cover the pinhole up, so the inside of the box did let any light in. We create the flap with card and black duck tape. After are boxes were all blacked out we then inserted the photographic paper into the box. We put the paper in our box in the dark room because if we put it in, in the light it would ruin the paper and the picture will not come out.
When this was done we had to go to the locations where we wanted to take our pictures and had to leave our camera’s there for 30 seconds. Once we had taken our pictures we had to go back into the dark room to take our pictures out of our boxes and process them. Following this we had to place our photos into 3 different trays with different chemicals in so that the picture developed. The first tray we placed the paper into was called “the fixer this made the image come up on the paper. We had to leave the paper in the tray for 30seconds , after this we had to place it in the second tray which was the “developer” we had to leave it in the tray for 10 second and the last tray was “the stop” this kept the image the on the paper and we had to leave it for 30seconds and then took it out. If we were happy with the photo we had to place it in the “stop” tray for 5 minutes. By doing this it keeps the image there for longer. Once done this we had to wash the image in water and then put it through a dryer.  I then did this process 4 times.


When I had taken all my pictures I had to scan them into the scanner. Each of pictures that I scanned I had to change them into jpeg files. After this we had to make a g mail account and a bogging account on www.blogger.com. I then had to place all my photo on to Photoshop. Once all our images were on photoshop we had to invert them . This meant that we changed them from negatives to positives.

Analyse

Overall I think that all my pictures have come out well and I am pleased with them. Although I feel that the pictures that I took inside weren’t as good as the images outside. With my first picture I think I left it capturing to long (30seconds) I then took my picture with just 20 seconds this made my images come out much clear. For the next 3 pictures, they all came out really clear. My last photo that I took I didn’t come out very clear, this was because the paper that I had placed in my box wasn’t big enough to capture the image. After it had done this I got a bigger piece of photo paper and it came out fine. I also found out from my images that they were clearer when the shutter wasn’t facing the sun and was in the shade. If the shutter was facing the sun the image would come out completely black .The images in the sun didn’t take as the light was to bright.
Once I had put my photos on Photoshop I was very happy with them as they were clear and you could make out what the images were.
Research & development.
Since pinhole camera , it has made development in technology we use today. Pinhole photography was the first type of photography made. In the past 10 years there has been a huge development in photography . This is due to there being digital camera, the images that come off a digital camera are very clear and are very good quality. There is also been a big improvement in editing programmes were people can change the colour of the images, the size and add things in. This has made images better quality. There are now also camera phones which most people always have with them. Pictures that are also becoming clearer on phones as the cameras are becoming better. The lens has also had a big improvement in photograph as the lens has become bigger which is making the images better quality. Since 1935 there has also been the making of film cameras which lets people record special moments. Video cameras have also helped Computer games as people are able to base them on things they have filmed.
Camera’s have also change the way photos are stored. Photos used to be stored on pieces of paper like the pinhole camera and then there was a film that went into a camera which the photos went onto, when looking at this film the pictures was seen in negative. Now a day’s digital cameras have memory cards that store the images on.


These images are the positives that i have changed on photoshop. I did this by puting the images on photoshop , then going on ivert  to change the image from a negivtive to postivive.









These images are the images that i took with my pinhole camera.




Research




This image was taken in England and the photographer has called it “The Ghost of Portmellon Cove” They have called it is because where someone has stood in front of the camera it looks like a ghost. This picture is landscape as it is a image of the beach.

Justin Quinnell takes a range of different type pinhole photos. He does  Slow light like this on of Clifton bridge, Black and white , Colour and images done inside the mouth.
