I know it all depends on the person but I have never done this and have no idea about any estimates: Let's say I go shoot someone but then I send my RAW photos to someone else that is good with Photoshop to edit them and send them back to me. What is the average price for this? Like I said I have no idea that is it $1.0 per picture? or $10.00 per picture ? or $50.00 per hour? Just some ballpark.
I have used retouchers in China like these guys that charge $5/picture (and less for large quantities) and aren't bad for basic retouching. For more skilled retouchers $10/picture is common. For pros that are more on the "graphic artist" level the rates I see run $50-$100/hour.
As a professional photographer it takes me about 20-30 minutes per photo AT LEAST whether I'm editing a photos of inanimate objects or humans. It can take much longer if you're actually altering the information in the image. I've been asked to remove cords, change house numbers, edit out telephone lines, etc. That 30 min when editing a portrait includes tackling blemishes, skin imperfections like dark circles, smoothing skin and whitening teeth. Depending on the project I usually charge $100/hr to edit photos, but I live in NYC. Where you live is another factor.
All my clients have been ecstatic once they see the final photos. I charge a premium bc of the effort I put into my edits. If you want repeat clients rather than a one time gig, or if you want your clients to refer you, I would highly recommend getting to know photoshop and definitely spending more than 5 min on each photo. That way you don't have to outsource and can keep all your hard earned cash! When I first started I'd edit photos for $25/hr, so pricing depends on your experience and your ability. Youtube and google have foolproof tutorials on everything!
Hope this helps.
shootdotedit are used by a lot of photographers, especially in the wedding arena, and their processing and pricing would be a useful model to judge against.
First of all you need to categorize what you nean by "Edit" them.
This is probably not an answer but a big comment.
Lets think for example in Portrait. In general depends on the overall quality of the photo.
Remove imperfections on skin... This depends on the skin, ilumination, makeup.
Color corrections... This is relative if you do not have a target white balance for example. But can range from simple "look" to equalizing diferent shoots to look the same.
Hair masking, of course depends on the background, and the hair.
Or probably you are looking for an artistic interpretation of your original photo.
As a Professional Photographer and Retoucher, it should NOT cost less than $5 to retouch a photo unless you are doing very high volume minimal retouching. It takes about 3 minutes to retouch most photographs on the basic side, longer with more advance processes. The price per hour generally is between $85-120 per hour depending on the studio and if it is for a commercial venture. If you are being charged less then they aren't paying their employees very well at all, the employees are just pushing a button on a preset and you are not getting a professional service.
Image editing cost depends on multiple factors like specific requirements, location and the complexity of images. If the picture is so old and worn one, then it will take more time and expertise to finish the job. So, the cost will depend on required time, expertise, expected quality of output, and the condition of the source picture. Another aspect on which the cost will be influenced is the type of retouching work you are asking for. Usually, for hourly package start from: $6-8 hourly & $1,000 man month.
