Hotspots aka those shiny spots are very common during harsh summers or in the winters when the sun is just creeping in your clicks. They are hard to erase, as it leads to erasing the minute parts of the photos leading to anawkward look of the click.
Those erasing leaves the spot looking pale or over sweaty. With other photo-editing software, it becomes a common editing saga that all of us can try it. But, trying ahand at the photoshop gives you all that you need.
Using layering options to remove any spots, or reducing the colour contrasts around the pic, and using the filter options one can seamlessly get a pic of high quality, looking like captured by a pro.
Why do you still use the old ways to reduce, when you have one stop shop for all!
