brrttpaul Posted July 16, 2017 Share Posted July 16, 2017 Hi guys having moved from a OSC to a mono (ZWO 1600) i think my biggest problem is in saving files. If I use PI to stretch the image and do curves saturation etc untill I am happy with it, what I have noticed when I save and say open it in PS or LR it looks over exposed. I am obviously doing something wrong when saving as in PI it looks great in PS its blown out. I usually save as a TIFF file. where am I going wrong?

RichLD Posted July 16, 2017 Share Posted July 16, 2017 Are you saving the TIFFs at 16bit? Link to comment Share on other sites More sharing options...
brrttpaul Posted July 16, 2017 Author Share Posted July 16, 2017 yes I think so Link to comment Share on other sites More sharing options...
Adreneline Posted July 16, 2017 Share Posted July 16, 2017 I am sure to be corrected on this but, assuming I am making a one way trip to PS, I Resample the image to 300 dpi and then perform ICCProfileTransformation with Target Profile set to sRGB IEC61966-2.1 and Rendering Intent set to Perceptual (photographic images); I also check the Black Point compensation. I also then save as a 16 bit TIF. There are others with far more experience of PI than me so I am sure more advice will be forthcoming. Good Luck!

I did see that so I was thinking it may be this, also in PS when I open it the black point is way lower down below my histogram by sliding the pointer up I am getting to somewhere nearer the exposure that i had in PI so will try changing the values like you said cheers Link to comment Share on other sites More sharing options...
