I am a professional graphic and photo designer and editor as a freelancer and would rmend every one Adobe Photoshop and Adobe Illustrator for this purpose but the problem here is that both are not for free. (in this case I would rmend you the following software) #1 According to me in the field of vector designing is Gravit Designer. it is a full-featured vector design app from thepany behind Corel Draw. It's suitable for all sorts of design jobs from screen app and icon designs to presentations illustration and animation. With a clean and intuitive interface that adjusts itself as you need it this free graphic design software packs a wealth of tools for creating detailed and beautiful vector editing tools without Photoshop's price tag or GIMP's immense toolset Photo Pos Pro should hit the spot. Built with image enhancement and editing in mind it's perfect for typical photo editing tasks such as fixing contrast lighting and saturation but it'll also stretch to more advanced techniques. It boasts an extremely user-friendly interface as well as an in-depth help system to get you started and if you want to expand its tools to fit your needs there are plenty of expansions and plugins available.
