Problem between PI and Photoshop

[thierry31380]

Hello,
i m trying PI and i love it s really a powerfull software and i will buy it sooner

I encounter a problem between PI and PS CS4

after processing a picture in PI, i save it in Tiff 32 bits, if i open it with PS the picture is very much bright than in PI, i have to adjust curves and levels

is there a parameter to preserve adjustments in both software?


Sorry for my poor english, hoping you understand what i mean

Thanks

Regards

I always use the 16 bits TIFF mainly because not everything works in 32 bit.
Perhaps, You should re-post in the other forum ===this is a possible bug?

Hi Thierry,

Welcome to PixInsight Forum! And thanks for the nice words

This is not a bug. It is simply that PixInsight and the other application use different numeric ranges to represent pixel sample values in floating point format. PixInsight uses the normalized [0,1] range where 0=black and 1=white. The other application I don't know.

is there a parameter to preserve adjustments in both software?

In PixInsight, yes. You can define the default input range for floating point FITS and TIFF images:

- Open the Format Explorer window.

- Double click on the FITS (or TIFF) format item, on the left column.

- Enter the appropriate lower and upper range values in the corresponding fields of "Default Floating Point Input Range".

- Click the OK button.

Note that this only changes the way PixInsight reads floating point images. Floating point images written by PixInsight will always be normalized to the [0,1] range.

In the other application I don't know if you can specify a default input range for floating point images.

Thanks guys for reply,

mmirot, you are right, saving in 16 bits there's no more problem, levels are same.

Juan: i don't know where is the setting in PS, but now that i know that is working in 16bits i have  no more the problem
