I ordered some cheap extension tubes a few weeks back and finally had a chance today to have a play around. I think I have also discovered a cunning way of adding a backdrop without too much hassle as well. The fern frond? is about 11mm wide. PP included cropping, levels and sharpness, all backgrounds are real and not added post. Further to my post from yesterday, yes I can now see that I do indeed have dust on my sensor, bottom left in last picture and visible in a few of the others, any tips on how to remove other than the cameras built in cleaning?
