Task 1A TIME.

This technique is called double exposure, double exposure is the repeated exposure of a photographic plate or film to light, often producing ghost images.

Another technique is called  burning negatives. it is done by burning the negatives or the picture that was made.

Sandwiching negatives is as technique that ends up looking very similar but it is created in a different way,it is created by putting two negatives or slide into the film carrier of the enlarger and printing it on one piece of paper  

Painting with developer is a technique where you expose your chosen photo then before putting it into the developer you get a paintbrush and dip it into developer and paint over your exposed picture.

Solarization is a technique where it creates the effect of almost inverting the colours or in my case the black and white, you can do this by exposing your image then you put it in the developer but as it starts to develop you take it out and expose it again under light.

The next technique is called baseboard distortion, this is made when you expose your image you move the baseboard around or on its side and it creates a curved or blurry effect on your photo.

Scratching negatives is a technique where you put scratches preferably with a needle or pin onto the negatives and it makes white scratch marks on the photos just another way of experimenting with your negatives.

adding textures in the darkroom is created by doing as normal but when the paper is ready to be exposed upon you put a texture over the top of it preferably a translucent texture so you can see the original image as well as the texture. (i couldn't find an image for this)

A photogram is a simple image created by placing objects onto a sheet of photographic paper, and exposing the paper to light. 

Distressing a negative can be many different things and doesn't have to involve the darkroom at all, it is mainly just about destroying and ruining your negatives to use it as an effect, some include standing on them, use sandpaper on the, bend and twist them about just anything to ruin them a bit.
