San Francisco, Jun 22 (IANS): Apple CEO Tim Cook has appreciated pictures of Mumbai shot on Australian photographer Andrew Kneebone's iPhone XR.

Kneebone took to Twitter on Friday to share colourful shots of Aamchi Mumbai and added the #ShotOniPhone hashtag that caught Cook's attention.

"I've always believed that the world is a beautiful place! India has a beauty all its own, from the cobblestone streets to the unique colours painted on the walls. I made these wallpapers from photos I took on my iPhone XR in Mumbai! #shotoniphone," Kneebone captioned his shots.

Cook re-tweeted Kneebone's album and captioned - "Love these #shotoniPhone photos! Thanks for sharing such a beautiful glimpse of Mumbai, @AndrewKneebone."

The pictures shared by Kneebone are not the regular landscape and portrait shots, rather they are of punchy wall-art colours, dried yellow flowers against the grey stony surface and other such pictures that fall under the abstract category.

Several people replied to Cook's re-tweet with photos they themselves shot using iPhones.

Some users also shared pictures clicked on an iPhone in comparison to pictures shot on some other phones.

Replying to Cook's Twitter gesture, Kneebone wrote: "Hey Tim! I'm so overly thrilled that you love them (to the extent only my mates can explain). The combination of an impromptu photo shoot of vibrant Mumbai and your beautiful technology resulted in lots of people's day being brightened just a little. Which I think is pretty cool."

Kneebone has also shared his shots from Mumbai on his Instagram handle.
