Hi Gav
Now they look like normal and edible Onion Bhajis. Nice One.

Also look close to BIR Bhajis.
(Your Pic) Just go into your phone settings and up your exposure a little, or it
might have HDR - High Dynamic Range feature, if so, switch it on, should make a difference.
Here's your same Pic with only the exposure tweaked 5%

cheers Chewy
