    My wife just upgraded to an iPhone 14+. As part of her testing the new toy, she took a picture of a flower arrangement on the table in front of her and emailed it to me. When the picture was opened in FastStone, my default viewer for random images, it looked like the first screenshot below.

    I saved the file she sent, opened it in my editing software and saved it as a jpeg (without doing any editing adjustments -- just saved as a new jpeg file). The screenshot of the result (also via FastSone) looks like the second (normal) screenshot. What is going on with jpegs from iPhones?

    Or is it just a quirk in the FastStone viewer?

    Was the software set to display underexposed areas as blue?

    The last time I saw something like that, it was bad / failing RAM
    I don't own or use FastSone Image Viewer.


    Edit: having said that, if it doesn't appear anywhere else and only in FastStone, I would uninstall and reinstall the software.
    google search how to remove FS completely if there is no uninstaller.

    If it's a bug, there may be an update available?

    That’s exactly what it looks like to me too.

    Thanks for the suggestions. I have confirmed it is a FastStone settings issue.
    I have used FastStone for more than 15 years and my version is very old (shows loaded in 2016)
    I could locate no settings that were designed to display underexposed areas in a special way.
    However, under a tab labeled CMS in settings, FastStone was set to "Enable Color Management System (CMS)"
    When I turned this OFF, FastStone displayed the image correctly.
    I had only seen this effect once before and it was also on a picture someone sent me from a phone. But I didn't then explore the "why" as I have now.
    Apparently an incompatibility between jpegs from iPhones and color management in FastStone --- at least FastStone of 2016 vintage. 😃

    Thanks. It has never occurred with any image other than from a phone. It is only a problem when initially viewing an image and is immediately remedied by disabling color management or by re-saving in my separate editing software -- even with no edits. I may download an updated version of FastStone. But not high on my priority list since this is a rare problem.

    Why would you not download the lastest version of FastStone? It is free.

    My hunch is that the iPhone is using Display P3 color space, which the older version of FastStone does not recognize. Without seeing the original, hard to say. Some people predict that DCI-P3 will replace sRGB as the common colorspace of the web.

    Yes. It’s Display P3.

    Until now, there seemed to be no urgency to update because the old version of FastStone seemed to do everything I needed it to do. I'm a sort of "if it ain't broke ....." kind of guy.
    But now I certainly have a reason to do so and will.

    I’m certain the misquote was an error…but I never said that, or questioned your decision. I provide information. What you do with it is all you.

    Jeff,..
    You are correct, I was responding to a question from California Creeks (CAcreeks) and, while attempting to eliminate some of the unrelated portions of the thread to which I was responding, I inadvertently linked his question to your name.
    I'll have to learn more about how the elimination of previous text (that we used to label "snip") works in this new system
    This thread is also the first one that involved my having to learn how to post images -- that is also different in that it is a two-step process.

    By the way, I appreciate that, like me, you have revealed some personal information in the "details" link in your account. Wish I knew more about others who I am exchanging ideas with.

    No worries Doug. I probably should have used a wink or something to indicate I wasn’t particularly bothered — or surprised. Snipping quote strings can be confusing and I'm just happy to see people doing so. (So many multi-quote strings to reply “me too”.)

    I wanted to set the record straight because misquotes tend to get “repeated” in subsequent replies. One great feature of this forum (so long as it isn't misused) is that there doesn't seem to be a time limit on editing. iIf you wanted to edit the original substitute @CAcreeks for @jaberg in the string quote=“@jaberg The Preview button lets you double-check your work, or edits, before committing.

    Let the learning (or at least the lecture) commence!

    There are (at least) two ways to accomplish what I did here. I used the first method, which I find easiest.

    To pull a single passage from a long quote (or series of quotes)

    Without hitting reply, select the relevant passage from the body of your original message, then hit the Quote button that appeared adjacent to the selection:

    IMG_0191.jpeg

    This creates a reply box with the quote, properly cited, already inserted. A very cool feature of this forum is that once that reply box is onscreen, you can scroll through to the thread in the background to highlight and quote additional passages — they’ll be inserted at the cursor location within the reply box.

    Once you’re used to how this works it's very easy to pare long quotes down to the parts you want to address.

    The hard way is, of course, to quote the full message and edit the text. This illustrates the text snipped from your original quote to produce the results above:

    IMG_0192.jpeg

    The important parts are that the correct author’s name appears in the quote= brackets at the top, the text you want to quote is cited, and the block ends with /quote in brackets. You’ll want to be sure no additional “quote=“ or “/quote” bracket strings, or bracket pairs, are present.

    Simple as… Just remember the Preview button is always there.

    I hope this helps.
