Colour Filters for Phone Camera

Today, we will learn how to make colour filters for a phone camera.

• Scissor
• Glue
• Cellotape

• Cardboard
• Coloured transparent sheets
• Paper fastener
• Paper
• Earphone Jack

Take 3 rounded pieces of cardboard which have the same radius, the radius of the pieces depends on the number of colours you want to have in the filter, if you want more filters, more the radius.

Here, i have taken radius = 4 cm. , Because i required only 3 colours(green, blue and transparent).

One of the disc should have an extension that would help you rotate the disc which contains the filter, Now on this disc make holes or cut-outs, this is where you would paste the coloured transparent sheets, make sure that the the holes are big and equal.THIS IS YOUR FILTER DISC.

Take the other two pieces and cut one hole(or cut-outs) on each disc, they must be equal to the one we made in the first disc.

Take the coloured transparent sheets and paste it on your filter disc.

Cover each disc with white paper.

Make holes at the centre of each disc.

Stack them on top each other, make sure that the filter disc remains at the middle.

Join the disc's together using a paper fastener.

Paste cello-tape on each end of the fastener.

Keep the filter on the lens of the camera and mark the point where the earphone hole touches the filter.

Paste the earphone jack on that point.

You have made the camera filter!!!!

You could also use the charging jack for this purpose
