  • More about Adox CMS 20: http://www.theonlinedarkroom.com/2015/04/adox-cms-20-ii-adventures-in-development.html Low contrast 1:4 is most interesting for "normal" photos.
  • Created discussion thread Lenses for film in LF and MF
    I found this lens test for large format: http://www.hevanet.com/cperez/testing.html Here is medium format: http://www.hevanet.com/cperez/MF_testing.html Really a large work in testing but I am ...

    Yes it is not working well but I can't see any damage.  At pentaxforum you can find some opinons about sharpness some 10 some 7.....bad quality control?
  • Very interesting! Some of the low budget lenses for black & white enlargers are they triplets ore more advanced? They often use M39 thread.
  • Created discussion thread How important is the bokeh for you?
    I saw this triplet design with soup bubble bokeh: https://www.bhphotovideo.com/c/product/1297909-REG/meyer_optik_g_rlitz_mog2950pk_2_9_50_trioplan_lens_for.html
  • And this is EOS 5DSR Well, you can crop some more....
  • The only Sigma Art I have seen for Pentax now are 30 and 35 mm. This must be one of the most odd lenses for Pentax: https://www.bhphotovideo.com/c/product/1297909-REG/meyer_optik_g_rlitz_mog2950pk_ ...
  • Very fine dog portraits! Best regards!
  • Created discussion thread Your first contact with digital images
    It must have been around 1996. One of my friends sent me an image from the Frankfurt Automobile fair. It was in size 640x480 (VGA). I looked at it for a while and my opinion was very clear. "This ...
  • Some of the results are strange. It looks like a focus problem. One example is at Folding Cameras Perkeo with 75 mm lens- maximum center sharpness at f/16. Wrong focus, or? Even many of the large ...
  • Most likely HX90V is the best if the long end is often used. Here you can see som crops from Imaging Resource testing HX90V. USAF 1951  center at 4.1 mm USAF 1951 center at 123 mm USAF 1951 center ...
  • Thank you Guy!  That means EV8-EV10. Yesterday we had really bad weather here in my town in Sweden. The maximum EV outdoors was 9 for a few hours....

    Now I have tested them all. 40 mm/2.8 is not very good. You need to go down to f/8 to get any kind of sharpness. But the othes are much better so I will use them.
  • OK the poll was bad and I was too late to remove it (must be done within 5 min). Now I have some info about monitor EV. Most are in the range EV6- EV8. If you compare with prints on the wall this ...
  • OK it is close to EV9
  • Yes but isn't this the typical question going from analog to digital: How many MP is needed to see all details? The only way in this case is to compare like 20MP, 10 MP, 5 MP and 2.5 MP. When will ...
  • Why are you asking for so small printer when people use 55-66" 4K TV? After all it is only 3820x2160 pixels. Well not so much if you compare with how prints are used regarding light. Yes the poll ...
  • You are now at EV 7 so something like EV 7 -EV 9 shold be typical for your monitor. Yes this poll was not very good , I am sorry for all confusion! For me EV was not so strange. When I started ...
