colour management

Unread postby JBPhoto » 16.02.2007 08:31

Well I have found the workaround for colour management I think. If I select 'save as sRGB' rather than retaining original colourspace from camera it seems to display correctly in all programs :) - as our lab only undersatnds sRGB this is not a problem

You can also use Edit\Use color profile\sRGB command to convert the image to sRGB program before editing it in HF.

I've heard things in the past about changing color profiles making an image get a color cast. Does this happen in Helicon Filter, too?

Yes this is possibe. sRGB space is smaller than Adobe RGB. Moreover, each conversion depends on the curve quality and rounding errors.

But in most cases you will not notice this, because your Adobe RGB image is converted to screen space (close to sRGB) on the fly. As far as I know only few printing devices can reproduce wider gammut than monitor.

You are right!

I use both colors space and switch from on to other one with no visible change on monitor!
The difference is noticable especially with fine art inkjet printing that use wider gamut than kodak and fuji minilab (wich usesSRGB) or before a CMYK conversion for press!

A photographer that plan to giclée print or edit should choose adobe98!
When working for or with people preparing documents for press, they prefer to have photographies submit with this color space to match their color space!
