Hi Cristian and guys,Sorry for the no posting but had to take my son up to Coffs Harbour for a few days so had to drop everything and just got back.
Thanks for the ronchi images Cristian, I have downloaded quiet a few different programs since and yep Ronchi for windows is one of them. Great program also downloaded a program called couder mask and cauder32. Gee this will make it easy the first will give me the figures and print the mask and the second all I have to do is put those figures in and put in my measurements and it does the rest for me. Anyone have a go at these programs are they reliable?
As to my lap and the dog buscuit, (Roger) I had such problems getting anything I was happy to get the resin. I think my lap might have been a bit on the hard side as only had to trim it every 3 hours or so and you have to push very hard with the thumbnail to get the smallest mark!! Also the pyrex disk I bought was very old and rough but cheap $12 so had to give it a go.
I shall compare the ronchi images tonight and see how close I am to them.
Would it help to get a finer grating also? any benefits?
I have been enjoying doing all this and I would get aperture fever if I had the money to back it up!! I still might tackle making the secondary as yet. Thanks for all the help so far guys , I might need some more help when it comes to reading the zones and shadows..I shall post some more pics as soon as my wife brings back the camera!!!!!
Regards Gary
