Benesotor - I make two processing passes on my images prior to client delivery.
RAW PROCESSING - The first past is when I process the RAW files at the end of the wedding day. These are the global adjustments for exposure, WB, contrast, highlight, brightness, shadow.... all of the GENERAL traits. Every competent photographer does this to whatever image format they use.....and I don't ask the client what sort of lighting style they prefer.
PHOTOSHOP POST PROCESSING - This is what folks generally refer to as PP, or retouching. This will include blemish removal, glare reduction/removal, red-eye removal if any (VERY rare), hair removal, skin smooting, cloning in/out items, artistic vignetting (or not) and sharpenning. I don't do this type of work until the client selects the image for his/her final album, or as an enlargement in a print order.
My clients don't provide stylistic or artistic input to my work.
They've already hired me on the strength of my portfolio and/or referral. The work stands on it's own. They may point out a particular blemish or intrusive object in the picture, but that's about it. As RT mentioned, I don't ask for their "processing" help. Do that and you'll be giving your labor away for free, and they'll never be satisfied.
The fact that they booked me for the wedding, demonstrates the trust they've placed in my talent and reliability.
