Pics have a slight purple haze when uploaded to print

[angeloa76]

Ever since I've used the new Lightroom the past couple of years to edit pics, any pic I try to print through printing sites like Mpix, canvaspeople, or Wal-Mart, winds up having a slight purple haze over the pic.  If it's a regular JPEG pic that has not been edited, it's fine.  Even an edited JPEG pic though has the haze.  I mostly shoot RAW and begin editing from there using both Lr and Ps.  Am I missing a step after changing exposure, clarity, and color?

Most likely you send them a file which is not in sRGB. These consumer online print services assume that anything you send to them is sRGB, and they don't check if that is really true.

Thanks,

I'll check on that in my pics

Still doing it, even after editing a photo from scratch, changing the sRGB in editing and uploading to Wal-Mart.

What do you mean with "changing the sRGB in editing"?

In Photoshop I went into the Assign Profile tab and changed it to sRGB before saving it as JPEG.  Also, my camera was set to sRGB already too.

Neither of those settings has any influence on the color space of the exported images. That is done in the export panel in Lightroom Classic. In Lightroom CC you can only export to sRGB jpegs anyway.

How do I calibrate then?

Calibration is done using a hardware calibration puck such as the Spyder, Colormunki, etc. They are typically between $100 and $200 to purchase. Most photo clubs have one that they share and you can rent them from places like lens rentals.com. It is unfortunately essential to do this if you want your prints to come out right. The calibration on many displays is terrible out of the box.

That is wrong. Never use 'Assign to profile', always use 'Convert to profile'. When you shoot in raw, the camera setting is irrelevant.

Using those service you have to make sure you send the images in sRGB (set the export in Lightroom to sRGB) and that your display is calibrated using a hardware calibrator. In this case my guess is that the last step hasn't been done and that you are inducing the purple haze by editing on an uncalibrated display.

The above pic is what it looks like on Wal Mart's page.  I'm having to resize the original to post it here for comparison

Do the prints come out purple or like you see in Lightroom. Note that many

browsers on windows including the built in one are not correctly color

managed and will never show you the right color even if you calibrate.

[angeloa76]

Yes, if the pics are printed, they turn out the with the haze.

I'll try convert next time. 

Thanks for the input guys.

[angeloa76]

Converting to Profile worked.  Thanks for the help guys.  This has been aggravating me for quite some time.
