Answer 1

Photoshop is no doubt a great choice for editing your photos but it's not just limited to a few photo editing tools, it' way more than that.

As per your questions, follow the below steps by which you can remove blemishes and poor color quality from your photos using photoshop.

Before we start, if you don't know about the photoshop then here is a quick definition.
It's photo editing tools that works layers by which you create various kind of effects on your photoshop and can also merge, edit, color, watermark, brushes and what not.

Step 1: The first step is to create a duplicate layer on your image so that you can seperate your work easily. You will see that a new transparent layer has been created in the layer panel.
Step 2: Not it's time to use the brush that can do magic for your photos. Pick the spot healing brush from the toolbar, if you can't locate it then hover your mouse on a healing brush looking icon, it will display name of that brush.
Step 3: Once you find it, it's time to brush it actually but only on those areas where you want to do the magic.
Step 4: Make the brush a bit bigger than the blemishes and click on the blemishes, it will go right away.
Step 5: Continue this until all the blemishes go away, don't overuse it otherwise it will worsen your image instead of beautifying.

Finally save your file and it will save in the edited layer instead of actual background layer.

For the color correction, press ctrl+L or open levels from the filter and adjust.

That's it. I hope this will help.
