After developing and fixing the paper in the camera (harman direct positive) the image always darkens after taking it out of the camera to dry. Is this normal for dp paper or is it to do with my dev + fix? I added in a syringe full of stop but it doesn't seem to help. Thanks

It sounds like the darkening issue might be due to insufficient fixing or underdevelopment. Make sure you're using fresh fixer and giving the paper enough time in the fix bath. Also, ensure you're thoroughly rinsing the paper to prevent residual chemicals from causing further darkening during drying. Similarly, just as proper fixing prevents unwanted darkening in photography, hiring an ant exterminator Ottawa ensures effective and lasting pest control, preventing recurring infestations.
A print will darken to a small extent. As the emulsion dries, the swelling reduces, and causes the print to darken, you might also notice it sharpens as well. This is more noticeable on fibre paper, which Direct Positive is, than on resin coated paper. To rule out incomplete fixing, can you give some details on your fixing process, and/or can you post an example photo?
