    Default  "convert to sRGB"  
      
      

    For those of you that keep saying this, does that mean that you're shooting in aRGB for jpgs and/or converting to aRGB from RAW? And if you are using aRGB to process in, why? Are you eventually printing to printers that can handle the wider gamut?

    I've always used sRGB in camara and in Photoshop simply for consistency between monitor display, web display and prints, and I keep seeing you guys say "convert to sRGB" so I thought I'd ask.

    I convert RAW to TIFF and work in aRGB I only convert to sRGB for web display and for printing if the printer I use calls for it.
    Editing in aRGB offers a wider color gamut and generally more information when editing.

    When I convert my DNG files in lightroom to work in photoshop, it puts me in pro-photo RGB. Maybe there is an option somewhere to export sRGB to photoshop but its not the default for me.

    ^ yea LR defaults to Prophoto, you have to change it if you want srgb.

    What monitor are you using that can accurately display all the colors in aRGB?

    Pro Photo is an even wider color space than aRGB, you'll want to convert to sRGB for web display. It's under 'edit' and 'convert to profile'.

    My HP Laptop monitor. As far as I know only the web restricts to sRGB.
    I would rather edit in a wider color gamut and set the color space lower for web display and print if I have to.

    Also, editing in the smallest color gamut "sRGB" coupld possibly cause clipping of saturated colors and detail so rather than risk it, edit in a wide gamut and convert down when necessary.

    it's kinda like saying "why shoot raw? JPG is good enough"
    More data = more to work with in order to fine tune and make the image look its best.

    To each their own. My way makes sense to me and may not to you.

    I didn't mean to sound like I was attacking your methods. Of course I would prefer to work with more data, but only if the device I'm working on is capable of displaying all of that data.

    From: http://www.jseaman.com/articles/srgb.html (I've been reading up a lot and this guy explains it all pretty well)

    ....Not all colors in aRGB can be represented on even the top of the line color computer monitors.

    While aRGB can represent colors with more saturated blues and greens than possible using the sRGB color space, sRGB has the edge over aRGB in being able to accurately represent the colors that are within its range. That is because aRGB chooses to represent more different colors while sRGB can represent finer shades of difference in colors (leading to better accuracy).

    Color space issues are heavily argued everywhere.

    I re-edit for each use, IE if I post to the web, I edit for that and post. If that same image gets printed a month later, I re-edit it for that printing. The only time I don't re-edit for a print is if I've already printed it at that size and the file still looks good to my eye when I open it before sending it off....

    but why did I say I forgot to switch to sRGB today in fact? Because ACR was set to RGB when I opened that last file and I didn't catch it... Not sure why it was, but it was. Then when I posted the image it looked funny, but I'd already saved the .jpg and closed PS so it wasn't worth re-editing since it's someone else's shot.

    I'd edit in 16 bit wide gaumet if given the choice and then mix down when you need to export.

    I shoot in aRGB only because I never bothered to look into changing it. My photoshop workspace is set to sRGB though.

    Now you're trying to confuse me. There's Adobe RGB, sRGB IEC61966-2.1 (the web standard and what 99% of people use), Apple RGB, ProPhoto RGB, and ColorMatch RGB. Which one were you in when you converted from RAW?

    that guys info is way off, and it shows in his pictures of birds. sRGB is crap. AdobeRGB(1998) is the standard and its the standard for a good reason. Every commercial photographer i know(including some pretty big name ones) shoots adobe RGB. Set your camera to Adobe 98 and photoshops working space to adobe 98. Use save for web to convert to sRGB and adjust the jpg compression. Most inkjets will look better with adobe RGB.
    Printers like the Fuji Fontier are sRGB so if your sending your prints to a printshop find out what printer and color space they use.

    thomps6 is absolutly right about sRGB clipping colors and detail when you edit.

    The only time sRGB should be used is if your a photojounalist shooting an event and your uploading your photos to the web with a short deadline.
