Sparkling featured image blur

Well, there’s a slight difference between picture I upload and the result in the featured image. The featured image is a little bit blur. Just a little bit, but I can see the difference.
I have tried to use image optimizer plugin, but nothing happen. I think the problem is on the visual effect when we drop the mouse on the featured image.

Can I just remove this effect? (The picture become a little bit brighter when we drop the mouse there). I want to see if this would help.

The picture below shows the different between the original (top) and shown in the site (down)

Or, do you have a solution for the blur featured image? Thank’s a lot.

Hi @erwinkeliat,

I hope you are well today and thank you for your question.

Could you please share me your site URL where it’s happening so that i can troubleshoot it?

Best Regards,

I LOVE SPARKLING SO MUCH. Just the blurry things distract my eyes.

You can remove the image blur effect by adding the following CSS code in the Custom CSS option of the latest version of Sparkling theme on the below path.

Admin Area -> Appearance -> Customize -> Additional CSS

    opacity: 1;
}
