Red angle

A shopping, cooking and baking day today ready for busy weekend of family guests. I placed my glass of wine under a side lamp expecting to see a rich ruby colour in my glass but instead the shadow of my iPhone was unexpectedly prominent. Strangely I liked the image. So this is my abstract blip - thanks so much Ingeborg!

Oh can anybody give me advice for a macro lens for my Nikon 3400 camera - it’s on my Xmas wish list but would like to give helpful directions.
Thanks
