Remarkable picture: only surpassed by the technicalities of the worm itself.
Often reminded how poor our engineering is compared to nature honed by millennia of evolution. Thank you.

Thanks Robert, I have just tried it both ways in front of zoom with camera on its back. Magnification only about 1:4. When I tell you the weight comparison of the zoom verses this particular SK150 you will understand why I am more than a little reticent to hang it off the stock zoom. Prepare for a s...

Shneider Kreuznach Componon 150

After playing with 3 and 5 dioptre filter lens at the front of the zoom lens I bought a Comparon 50mm against most advice proffered mainly by those who advocate spending a lot of money. This four element lens of 1907 Tessar design is described by the Wiki page as being of very good quality. Luckily ...

Well People, 60 buttons and L for line command! P is for paint?? No! Only one or two keys to push!!! Still stuck to day one!!! Mr Alzheimer is still at bay as you guys took me straight back in time to 1979 and mid 1980’s vintage computing and vintage CAD; I even remembered L39 for parallel line? The...

Hey People, If you are struggling to model a plate with a few holes you are going to struggle with any CAD software. The initial sketch on a plane for the part will require you to use a rectangle tool - click and drag to drop the other corner. Then at simplest select the circle tool - click and drag...

For those who are having difficulty can I once again recommend SolidWorks on a student license or WHY. It is so easy most students complete extensive tutorial by midday. How difficult can it be to spin a shape around an axis? Or take a tip from me and start with a bar and remove material as in turn ...

You may find SolidWorks far easier to create your model; even engraved or embossed lettering on a conical surface is quite easy and intuitive. If you are on a very tight budget you may want to use FreeCAD on a free operating system even! Take a look at threads on dpreview for legacy lenses on NX-min...

Never got on well with products from this company even though being a licensed user. It should keep Mr Alzheimer from looking in. Have used SolidWorks since 1998 but this also has similar license and pricing. Now, happily retired, playing (totally free) with FreeCAD - full 3D, running on Linux op sy...

By Ek Steve, I knew I was going to like this website; a break from the norm. Affinity from nearby Nottingham used to be Serif PhotoPlus which I have used for many years in various revision letters and numbers. It is so blindingly simple. They are nice people and recently gave me the serial code to i...

Thank you so much for these fantastic photographs. Having only just joined (as I do not like social media) this website is so full of interest I do not where to start. It is so good that I can take my time to study your photographs here. I am impressed by how you have judged the depth of field to op...

Hello All, My first post is intended to give further examples at the small and cheap end. I am much encouraged by that Russian who specializes in Snowflakes using a point and shoot with a reversed Russian lens taped to a plank of wood. He exhibits ART in NYC! Whilst I may not fully understand the ma...
