I've never tried to do that on the camera. If you download the Play Memories software you can edit your pics on a pc. Or a tablet, I used to use my tablet a few years ago.
Sony PlayMemories is a pain! The wretched camera won't let me download my photos without it installed on the computer! I hate being forced to install software I don't want. For cropping, etc., I prefer Pickpic freeware.
I've found a solution for the wishy-washy photos produced by my Sony WX60, as I detailed in post #8 on this thread on 18 Feb.
I searched online for free photo enhancement software. I don't want to use an online one, and more importantly for me it had to be a one-click tool, something like you get in Microsoft Office Picture Manager, because I don't want to be fiddling about setting sliders for all sorts of different things.
What I eventually found was
PhotoCleaner http://www.photocleaner.com/download.htmlYou open the software, browse in it for one of your folders of photos, select a picture and open it, which the program then displays almost full screen.
Next you simply click on a button 'Enhance Picture', and you see your photo change before your eyes in a couple of seconds.
There are buttons at the top to toggle between 'Original' and 'Result', then you can decide if you want to save the result or not. You can change the file name or you can leave it as it is which will overwrite the original.
I am very pleased with the results, it really sharpens my pictures up, removes the dull cloudiness from them and strengthens the colours. Greens are perhaps a little bit too garish, but I will try adjusting the sliders later. You can only do one photo at a time, and the window of your folder contents is small so with a big folder you have to scroll down each time you select another photo. There are shortcuts such as ctrl+O and ctrl+S which help speed things a little.
I hope this might be of interest to some people.
