Pink color while clicking photos in sunlight

No, not a hardware defect. I have wide angle lenses costing thousands of dollars that have CA.

CA won’t happen in all scenes or compositions. Generally it occurs when there is a dark object against a bright background. Review these images.

That’s an optical defect called Chromatic Aberration. There are two types, lateral and longitudinal. Wide angle lenses typically present lateral chromatic aberration and telephotos display longitudinal chromatic aberration. They are generally lumped together and simply referred to as CA.

Basically what’s happening is the light is not coming into to focus at the same point on the sensor. I’ll refer to the Wikipedia article on the subject at this point. If you want to learn more, please read the article linked to and we can discuss.

CA is one of the easiest defects to remove or minimize in editing software. It can also be reduced through the use of lens profiles in the software.

That is something else. CA is generally only a few pixels in width. The unusual shading of the blinds is something entirely different. It’s odd it follows exactly the size and shape of the vertical blinds in the image.

Please share the EXIF data for the image. I’m suspecting it might be related to HDR and/or fusion camera.

Thank you for sharing. Yes, it’s the Fusion camera in use. Try to not use the fusion camera and just tap the setting for the single lens, .5X, 1X or 3/5X depending on the iPhone in use.

White objects reflect colors around them. The unusual shading in the vertical blinds is the same color as the building and surrounding buildings. It could be a combination of the two factors.

You’re welcome. I enjoy sharing my photography knowledge and experience with others. I’m always happy to share what I know. I hope you have a great day!
