Ai 6.6 and 64-bit HDRi

[spark]

I have searched and can't seem to get an answer that makes sense to me. I just put SF Ai 6.6 on my iMac today, and upon running the software I see that I can scan a 64-bit HDRi but then the image is saved as a negative. When I scan it as a 48-bit file, without changing any other settings, the image is okay. Why is this?

Secondly, if the HDR part and presumably the i in HDRi can only be seen and used in the higher versions like Studio, what are they in Ai 6.6 for?

Thanks for the help.

Dear Neil,

I have searched and can't seem to get an answer that makes sense to me. I just put SF Ai 6.6 on my iMac today, and upon running the software I see that I can scan a 64-bit HDRi but then the image is saved as a negative. When I scan it as a 48-bit file, without changing any other settings, the image is okay. Why is this?

Because the 64 bit HDRi mode as well as 48 bit HDR color mode create an unmodified raw file, this means no modification takes places (including invert done with negative mode).

Secondly, if the HDR part and presumably the i in HDRi can only be seen and used in the higher versions like Studio, what are they in Ai 6.6 for?

HDR and HDRi modes can be used in any SilverFast version (SE, SE Plus, Ai and Ai Studio) to create unmodified raw files. Those files can be opened and edited afterwards using SilverFast HDR, HDR studio or SilverFast DC Pro which are our editing applications for raw files.

Cheers

I have the same problem! But how do I develop the 64bit in HDR Studio? I can't find any options to convert to positive..

Dear Customer,
in the "general" Tab there is an option Pos./Nega. after you draged the Scanframe onto the image area of your Negative please select here "negative" and everything inside the scanframe is converted into a positive.
