- Plan and prepare which image you are going to use- Plan at least 2 or 3 different fabric material to work with as it might not work the first time
- Create extra solutions in case your material doesn't work
- DO NOT USE a wood which as polish as waterproof on it.
- DO NOT USE POLYESTER

It's a photographic process which prints an image in cyan blue. It was first created by an English chemist and photographer John Herschel. This techniques as some disadvantages which are the exposure time. It is the best process for beginners as it is simple to do and the materials are cheap. It is possible to buy a ready made cynotype solution but it isn't difficult to produce one.

5. In the darkroom in the dark, paint  your material with the final solution. Try do paint  and leave it to dry in a place where the light from the door doesn't  touch the material. The reason why, is for after when you are going to exit the room

6. While drying print go on your computer, open photoshop, choose an image, invert it and print it on a transparency paper.

7. When the object where you are going to create the cyanotype is dry, go in the darkroom with your transparency. Put the image on top of the object. If using paper it's advised to use some clips for the picture to stay.

8.Once you are ready go outside and exposed it. About the timing it depends on how much sun there is and also if you want to overexpose or underexpose.

9.Go back to the darkroom and develop it, fix it, wash it and fix again. For every chemicals we have to leave it in for 3mins.

4. Mix both solutions A and B in the darkroom with the safety light. Once you have mixed the solutions, the liquid will become a yellow colour and will become sensitive to light. SO DO NOT EXPOSE IT TO LIGHT!!

1. Solution A mix 10g potassium ferrycyanide with 100 mL distilled water

3. Store each solution in 2 different containers. You can save both solutions if you conserve them at a fairly low temperature and in a  dark place

The plastic didn't let the light go through. Went blu all around instead. When light went through the glass.
Thanks of the blue lines that have been created around the plastic we know that it wasn't a chemical problem.
Polyester fabric didn't work, the liquid went everywhere.

Changed material which was paper.  And also because I haven't used plastic on top of the large format negative (also named transparency). Haven't put anything on top.
Left it longer exposure: 25 mins

Fabric material which was wood. Didn't work because of polish used as waterproof.
We know it wasn't a chemical problem as the colour of the chemical turned right eventhough everyone's attempt didn't really work. And also some of the glass we put over the transparency was plastic so it didn't allow the UV lights to go trough correctly.
