Images Render Differently on Website - Seeking Guidance from Photoshop Experts

Hello Adobe Community,I hope this message finds you well. I am currently facing an issue with image rendering on my website, and I believe the problem might be related to the Photoshop ecosystem. I am reaching out to this community in the hope that someone with expertise in Photoshop can shed some light on the matter and help me find a solution.

Problem Details:

  1. Color Discrepancies: When I upload images to my website that have been processed or edited in Photoshop, I notice discrepancies in color rendering compared to the original images. The colors seem to shift or appear differently on the website.

  2. Image Quality Loss: Additionally, there seems to be a loss of image quality, especially when the images are viewed on high-resolution displays. This issue is particularly noticeable when the images have transparency or are in PNG format.

  3. File Format Compatibility: I have been using various file formats (JPEG, PNG, etc.) exported from Photoshop, and it seems that the website may not be handling them as expected. I've tried different compression settings during export, but the problem persists.

  4. Color Profiles: I suspect that color profiles might be contributing to the issue, but I'm not entirely sure how to manage or embed them correctly for web display.

Steps Taken So Far:

  1. I have double-checked my website's image processing settings and ensured that the content management system is not altering the images during upload.

  2. I've reviewed Photoshop export settings and tried different combinations to address the problem, but without success.

  3. Checked whether any browser-specific issues might be affecting image rendering, but the problem seems consistent across various browsers.

Request for Assistance:

I would greatly appreciate it if anyone with experience in the Photoshop ecosystem could provide insights into potential causes and solutions for this issue. Has anyone encountered similar problems with image rendering on websites after using Photoshop for editing?

If you need additional information or specific details, please feel free to ask. Your expertise and guidance will be invaluable in resolving this matter.

Thank you in advance for your assistance!

When you Export/Save For Web, you need to make sure that it embeds the color profile (sRGB for web). All major web browsers are color managed and will display correctly using the document profile.

 

If you use Save For Web, turn on color managed display by setting Preview to "Use Document Profile". The default is "Monitor Color" which dsplays the image without any color management at all. This will not match a web browser.

 

If you use Export, it is unfortunately still buggy in its color management display. The file will export correctly, but it may not display correctly in the Export dialog. I'd recommend using Save For Web with Preview "Use Document Profile".

 

As for quality loss: If you have a 4K/retina screen, you need to be aware that all web browsers and consumer image viewers will scale the image up to 200% when they detect a high resolution display. Effectively, this turns your high resolution screen into an ordinary traditional screen. So yes, there's a reduction in quality in that it doesn't take advantage of the full resolution of your display. This is the industry standard workaround to ensure that the same material can be used everywhere, regardless of what screen technology the user happens to have.

 

Also be aware that some websites compress images beyond what Photoshop exports as. It may also be downsampled.

Thank you immensely for your prompt and detailed response. Your insights shed significant light on the issue I've been experiencing with image rendering on my website after using Photoshop.

 

Regarding the color profile management, your guidance to ensure the correct embedding of the sRGB profile during the export process is tremendously helpful. I will certainly switch to using "Save For Web" and set the Preview to "Use Document Profile" to align with web display standards. Your explanation regarding the discrepancy between "Save For Web" and "Export" functions in managing color profiles clarifies a lot, despite the latter's existing bugs in its display.

 

Your explanation about the quality loss on high-resolution displays like 4K/retina screens is enlightening. Understanding that browsers and image viewers scale images up to 200% for such displays and the resulting reduction in quality provides me with valuable context. Thank you!
