I don't use star rating for my photos. What is the point?
You rate a bad photo with one star rating, and delete it, but the star rating goes with it. May as well have saved yourself time by not rate it with one star, just get straight to deleting it anyway.
You waste a handful of seconds trying to decide if this photo is worth 3 or 4 star ratings, come on, 3 or 4 or 3 or 4 or 3, what a struggle trying to make up your mind. Aw hell, let's go for 4 anyway!
You rate your best photos a rating of 5 stars, but why bother? Surely you could just create an album (in Lightroom, it's called
Collection) and put any of your best or favourite photos in it, instead of looking all over your Catalogue for any 5 Star ratings.
IF I had to use the star ratings, then it is highly likely that I would not use it as a rating, but as a code. 5 stars does not mean best, it could be a code for taken using a Nikon camera, 3 stars does not mean okay, it could be used as a code for photos taken using a Minolta X-700 35mm film camera.
Or considering that I would import my photographs into Photoshop or InDesign to do some artwork or graphic design, I may give them 1 to 5 stars to remind me in what order to import the photos. Pick 5 photos I need, give them stars based on the order of import, for example 1 star means import this first, as I want it to be as background, 2 star means import this next, and so on, 5 star means the 5th photo to be imported.
Either I don't bother with using it as a rating, after all any crap photos would get deleted anyway, so there are no photos worth rated 1 star, or I use them to mean something else other than a rating system.
Beside, as
@j crossley would point out, and I agree, just flag any bad photos as X and delete them.
By the way, I have some movies from iTunes which I paid for and downloaded into my iTunes Library. Do any of them have star ratings? No. Why? Because if I like that movie so much, I would download it, and if I don't like that movie, then I would not bother downloading it. Why would I want to download any movies and give it a 1 star rating if I don't like it? If I don't like it, then don't download in the first place. If I were to use star ratings for my movies in my iTunes Library, they all would have 5 stars anyway.
