    Fixer and the Environment

    in Black & White Practice

    Posted

    <p>Hello, <br>

    I am doing my science fair project on photography and I need to know why my teacher lets us dump the developer into the sink but wants us to put the fixer back in the bottle. <br /> Is there a specific reason for this? Does it harm the environment?<br>

    Thank you!</p>
