innerimager Posted February 22, 2007 Share #1 Â Posted February 22, 2007 Advertisement (gone after registration) Perhaps I'm missing something but let me ask. I have the 28/2.8 ASPH which as Sean and others point out is a high contrast lens. When I use it in scenes where I want a wider dynamic range than I think it will give, I set the M8's contrast to lower than normal and preserve the shadows/highlighlights then adjust in post. (Actually I tend to do this anyway if I am shooting JPGs at least). Isn't this an effective way of "leveling the field" when comparing say a 28/1.8 ASPH and a 28 cron? It seems to at least deal with blocked shadows, though I can see that the general increased micro-contrast might still separate such lenses. best....Peter Link to post Share on other sites More sharing options...

In contrasty lighting, a lower contrast lens can effectively increase "X" by decreasing the contrast ratio presented to the lens by the sensor. All of this is independent of RAW conversion, shadow recovery, etc. Those are all ways of working *from* "X", the information recorded in the RAW file. They don't change X, they change "Y" which is the processed result of the information in "X".  In-camera JPEGs are another form of "Y". Increasing in-camera contrast decreases shadow and highlight detail in "Y". Decreasing in-camera contrast increases shadow and highlight detail in "Y". Neither of these have any effect on "X".  "X" is affected by: subject, subject lighting, DR of digital camera and lens contrast.  Thanks for asking because I suspect that this topic confuses a lot of people.  Cheers,  Sean Link to post Share on other sites More sharing options...
innerimager Posted February 22, 2007 Author Share #3 Â Posted February 22, 2007 Thanks Sean, I was hoping to catch you before you left! In fact, if I didn't see a response from you, I was going to bump it back up when you returned. best....Peter Link to post Share on other sites More sharing options...
