If you are a photographer, then the point of your reply may not carry much convincing weight regarding the OP's question.
Are you a photographer? Do you know how to adjust in Lightroom, Photoshop, ?
If the answer is yes, then you, like many of us, are not in the same league or shoes as the average wedding couple. A "couple" photos handed over to you, is incomparable to an unspecified number or RAW files given to a married couple.
Or anyone else.
After a few years of providing some RAW or unadjusted JPGs to various people for portraits and seeing the shots occassionally surface poorly tweaked or "as is" with my name connected as a "credit", I plan to avoid giving RAW whenever possible.
Unfortunately, your response does not carry a lot of weight. The reality is if you provide any electronic file at all, Once it is delivered to the client then it is out of your control. I have seen clients take Jpegs and Re-Adjust on I phones, crap edit programs, and totally destroy the look of the file I have provided. There is nothing you can do once you release a file.
The other reality is that IF you work in the wedding industry as a photographer, you will NOT get hired unless you provide digital files with your packages. The bridal market insists on it. So its a catch 22 situation with releasing files.
anyone can change the look of the file you provide and it doesnt matter if its a RAW,JPEG and DND file.....Most people have access to editing programs...you cant avoid this...Just the nature of the beast these days.
Photographers need to take the mind set of Film negatives out of the equation. Film days, we did not give away negatives. We went to print labs for negatives to be printed for photo needs......Those days....like the Edsel.....are long long gone. Film is DEAD. Digital in the new medium and clients demands will dictate how you will survive with this new era in photography.
