3D Printing: I'm back in the saddle!

It is almost 8 years since I've posted anything on 3D printing.

 

That's largely because its almost 8 years since I last touched a 3D printer.

Well now that I have my own printer...I'm back!

DSLR optical path: where is that spec of dust?

After a recent trip to Hurst Castle we noticed dirt spots on the photos from 2 cameras.

While giving them a clean, it occurred to me that there are quite a few places where dust and dirt can be a problem.

Spots on my photos

Although a few spots on a photo can be fixed by running the image through your favourite photo editing software, the source of the problem should be investigated.

If you use a DSLR, black spots are most likely caused by dirt directly on the surface of the cameras sensor.

I've noticed this problem with photos taken on my Pentax K-30 during the last few months, but only just found the time to take a closer look.
