Prefix file name underscore versus 8

[Zbadger]

I use Adobe color space for my 5D Mark 4 which uses a file name with an initial underscore. However I am finding that on some of my folders the majority of my files will be correctly labeled with an underscore but then a lesser number of them will randomly instead have an 8 starting off the name of the file. I contacted Canon technical support and they have never heard of this issue.

Almost every program including Windows can sort the photos by Date (and time) Taken.

And while Windows doesn't make it particularly easy to assign chronological names to a large group of pictures, Canon's Digital Photo Professional (and I'm pretty sure also Lightroom and Photoshop) does. So I think you can treat the erratic naming, whatever its source, as merely a nuisance. It shouldn't be in any way a show stopper.

You should [add] the EOS Utility to that list.  It allows you to rename files and create folders based upon criteria contained within the EXIF data.  For me, it is THE reason that I use it.  I can easily sort images by camera and date into unique folders with unique names.

White balance and several other camera settings ony effect JPEG files. If you shoot RAW, the sRGB or AdobeRGB setting has no impact whatsoever on the Raw image data file. That is set by your photo editor.

"I can just go to my RAW frame and process it how I wish and the RAW frame will NOT BE AFFECTED IN ANY WAY by the sRGB setting I have inputted in the color space setting within the camera menu (red section, page 2)."

OK, thinking I may make this more clear. Technically what I said in my last post is correct. In practice it doesn't actually happen that way specifically.  True, there is no WB or color space assigned to any Raw file. However, in order to view a Raw file a conversion must take place.  Your editor, LR or PS (best!) do that. How?  They us a small tag file created by your camera that does contain all the camera's settings. It is saved along with the Raw data file. That is what you see on your monitor. Or even on the camera's LCD for that matter.

You are now in your photo editor. The Raw file is unaltered and in most cases you can't even save back to the Raw file at all.  You have to choose a different format like jpg, tiff, etc.  That is where you set your color space.

In response to TTMartin, Bob and all who have contributed to this thread , my thanks and hopefully my final comments and question below.

TTMartin - If I did give it to someone in green mode, it may have been once and that should not account for the 150+ pics over 10 day folders that are with an 8 prefix.  

Bob - Windows does not do a good job or chronoligically correcting the date issue - I have tried and also screwed around a bit with Bridge and Lightroom.  Have not tried DPP though for reordering items.

Lastly and most importantly, I do not want this mix of _ and 8 prefixes to happen again.  So just to confirm with everyone  --  I will change my settings in the 5D MarkIV for color space to sRGB and not worry about that at all for my .jpg images.   But if after reviewing my RAW/.jpg images, there is a great image I want to have professionally printed, I can just go to my RAW frame and process it how I wish and the RAW frame will NOT BE AFFECTED IN ANY WAY by the sRGB setting I have inputted in the color space setting within the camera menu (red section, page 2).  Correct????

Not quite. I believe that in DPP, at least, (not sure about other editors because I rarely use them) the camera's color space setting will become the default setting in the editor. So before you do the conversion to JPEG, check to make sure that the setting is what you want. And in DPP, at least, the display setting and the setting used for conversion are separate parameters. So the editor may, for example, be set to display in sRGB (correct for most monitors) but convert to Adobe RGB (used by some printers) when producing a JPEG.

OK - now I am perhaps confused.  I download my images with EOS Utility 3.  Once dowloaded, I have a RAW and .jpg image for each frame.  I believe from your post and ebiggs before you, I should assume that since I have just today changed my color space settings to sRGB, that my .jpgs will appear as such.  Fine.  However, if I want to process and see the results of any particular RAW image under AdobeRGB which I might consider for professional printing, what need I do?

What Ernie says is correct for the editors he uses, but not for DPP. DPP uses no "tag file", and does allow you to save back to the RAW file. (It remembers both the original image and the changes thereto, so no information is lost.) Whether the current color space setting is saved, I'm not sure. It probably is; but the safe thing to do, whatever editor you're using, is to always check the color space in use before saving to a JPEG.

Thank you.  Right now under Adobe PS CC, it is set for sRGB.  I should make sure for professional printing that it states Adobe RGB.

Ensure that the editor's display color space is set to Adobe RGB. HOWEVER, that may not tell you what you want to know. The reason for using a particular color space is to match, as closely as possible, the characteristics of the device (monitor or printer) that you're using. So you may get a more realistic look at the final result by observing the image with sRGB (which most monitors prefer), even if you plan to print it using Adobe RGB (a slightly wider gamut recognized by some printers).

It's important to understand that color space is not a subjective display parameter like "Daylight" or "Cloudy", or another way of specifying the color temperature. It's purely a way of matching, as closely as possible, the capabilities (e.g., the number of identifiable colors) of the display device or printer. Sometimes you have to start by taking the device manufacturer's word for it. Then if you don't like the result, you can try a different setting.

Yes, ONLY for when you are processing the file to print with an Adobe RGB compatable printer.

Otherwise, for 'normal' processing for digital display (digital photoframe, computer monitor, web (social media)) then you will want to leave it set to sRGB.

"...not for DPP. DPP uses no "tag file", and does allow you to save back to the RAW file..."

I do use DPP4 on sporadic occasions. I am not a real knowledgeable DPP4 user true but DPP4 does use a tag or meta file.  It is very unlikely it files color space back to the Raw file. I know DPP4 can save to a Raw file but not color space.

Raw files have no color space, DPP displays data from the Raw file in the selected color space set in the camera just like any other post editor.  When you change the color space the Raw file will be reinterpreted into the new color space. But that is not saved back to the Raw file.  If it did it could never be changed if you set a smaller CS and wanted a larger one.  I.E. saved sRGB and want AdobeRGB.

You can set DPP4 to 1 of 5 color spaces. By default it is set to sRGB which has the smallest gamut.  The CS is defined to display or print but the CS isn't set in stone until you actually export the file to a jpg or tiff.  Up to that point you haven't really converted or altered anything.

My practice is to set the camera to AdobeRGB.  I only shoot  Raw. I don't save a jpg along with it.  That isn't necessary 99% of the time. If I am printing I leave it. If it goes to social media I change to sRGB as a jpg.
