    Re: Fun with IQ4150 Achromatic Images

    Just a follow-up to the above images. I zoomed in on this site and the images have almost no detail compared to my C1 V12 RAW processed images. I used to download IQ3100 images at 2400 PX long side, but due to the increased image sizes coming out of the IQ4150, I had to reduce them to 1800 pixels long side with the same quality of 83% and no sharpening.

    @algrove Some of these have a quite harsh contrast at least to my taste. Is that how they come out of the camera or is your processing?

    Hi

    Thanks

    Have you tried with just the 091?

    That should block out UV and everything below 630nm I think

    Thanks

    Yes I have, but seem to like the 2 filter approach best for now.

    I remember when CI was helping shim my STC adapter with the IQ4 we tested the 486 only and the red 091 only and also the 486+091. Adding the red to the 486 did not shift focus and the images had the contrast level that I like best. Some might prefer the orange 040 in cases where large white puffy clouds are present since the 091 to some eyes makes these clouds look a bit strange.

    I can understand the logic, the 486 maintains the auto focus and the 091 gives you 630 - 700 nm and high contrast . Being in Miami (Great Clouds) I usually keep the orange filter on the XF with 486 and the tech w/o the 486. Sometimes move to 091 you are right about the clouds

    I like your shots and also the the ones by Dr Paul who is using a lot of IR. For B&W contrast I find Sebatiao Salgado beyond words. Check It out, I think you would like it.
