    B&W conversion problems

    I use Photoshop CS6 to work on images and save as TIF files. Color looks just fine with Automate – panoramic images.

    Then I use Silver Efex Pro for my B&W conversion and I am getting these wierd patterns that I think are where Photoshop has joined the images to make the final composite.

    I did have it all set up on my work computer – which showed signs of impending death so I got a new computer. Had to have Adobe download and install CS6 for me as it would not take the DVD version for installation. Now – when using Silver Efex PRo to go to the B&W conversion for final files I am getting these lines. Never had them before – in years of use on the old computer.

    I am NOT going to a subscription version of Photoshop. How do I get the problem solved?

    A bit more on this.

    Spent time converting in Silver Efex Pro and then doing the same image using only Photoshop.

    The lines don’t show up when going to B&W only in Photoshop.

    I prefer the “look” I can get in SilverEfex Pro – but with this problem showing I won’t use it.

    Any answer/solution to this is welcome.

    This may be an obvious question but have you tried doing a flat grayscale conversion in Ps and then processing in Silver Efex Pro?

    I’ve seen artifacts like that in HDRs but usually with 8-bit images like cell phone shots where there’s too big of a gap for the dynamic range of the sensor to overlap.

    Don’t use Ps so I’m afraid I can’t help much.
