Now a days, SLR cameras are museum item. Lot of digital cameras have advanced setting and some even have editing options. Home users can do minor edits right on the camera.
Then there came camera phones. At the beginning, camera phones would just take pictures which was a blessing for lot of us. Now a days, cell phones have very high end cameras integrated with apps allowing the user to edit those photos right on the phone.
However, if you are looking to get clipping path, ghost mannequin editing etc, you will still need to use professional photo editing tools and use a computer to do your photo editing.
Some people edit photos for their own personal use. Some minor editing gets done by people who take pictures on the go and share them across various social media like facebook, instagram, etc. some people are serious about the image quality of the images they share on the social medias. Since the modern day cell phones allow people to do some editing, this type of editing are done easily at no additional cost to the users.
However, those who need professional editing like background removal, clipping path, ghost mannequin etc, it is a must to hire a professional photo editing person or if the volume is large, then hire a photo editing services company to do the job.
