I'm speaking about photos that get posted and asked about, by the OP, not a descent image that gets picked apart by the pedantics. Quite often there are ways to improve a photo by moving the camera a bit, not getting that telephone pole growing out of a head or paying attention to where the light was falling. Those are things that can help improve a photo. If a member is asking for comments in order to improve their work, then it does not help to simply say great shot, etc. if there was a way to better the image.

Of course, it might be that some of those commenting, did not have the understanding or knowledge to notice there were way to improve an image. That might be a case of the blind leading the blind.

Sometimes I see a lot of meanness on this site. People without understanding the economies of other members, throw out recommendations about buying like they are the ultimate authority on a subject, or right out boast like they think others are stupid for not buying the best on the market. Some people skimp whenever they can due to their financial situation. Obviously, you can't buy a generic Nikon, Canon, Sony, or Olympus body so while someone may have funds for that, they may need to skimp elsewhere. Someone in another post actually said they would not buy a non-OEM battery because it might be made in a foreign country! Guess what -- your OEM batteries are made in a foreign country! Other answers berate members for buying 3rd party items like battery grips. Hey, maybe they don't need the grip that can fall off a 100 ft. cliff and survive, maybe they just like a grip that affords a better hold when using the camera in a vertical orientation. Someone else said they would only buy HP cartridges -- I have an answer for that -- professional equipment like printers using eight or more cartridges notwithstanding, if you own a printer that you paid a couple of hundred dollars for, you didn't buy a printer, you bought into a very expensive ink program. Those lower-priced printers are so cheap because when you buy one, HP, Canon, or any others the manufacturer has you by the balls! You will be paying through the nose for your ink. Epson, and now Canon and HP have printers that use tanks which are easy to fill and cost a fraction of what cartridges do. Another possibility is that when it comes to batteries who knows who makes them? There may only be two plants in Japan/China/Taiwan that make all of them and just put different names on them. Look at the round head flash from Neewer, Bolt, and Godox they are all the same unit, just a name change. When someone asks for advice, it would be nice to see people respond with their recommendations and not put others down for things like not using OEM equipment. I would bet 75% of people here who act like people are stupid for not spending the extra bucks for a Nikon/Canon/Sony battery, use a flash that is not OEM. I work part-time at Sam's Club and I've had people tell me they would only buy Everyready Batteries over the store brand. Guess what -- they are the same battery! They don't understand marketing -- they can't believe Everyready would sell us batteries that would undercut the name brand. I explain that most big retailers will have an inhouse brand and Eveyready knows if they don't sell us a generic, someone else would! This way they get all the business. Ever see two gas stations owned by the same company across the street from each other -- it's about limiting competition. While I understand some of the group has the money to buy top-drawer on all their equipment, I think putting others down (and that is what you are doing when you state I would only buy xxx) is insensitive and is an opinion you should keep to yourselves. When I was 15, I worked in a manufacturing jewelry shop. We sold Rolex watches both 14 kt. and gold plated. They looked identical so one day I asked Mr. Hays (the owner) why anyone would spend 1200 or more for a Rolex when they could have an identical watch in gold plate for a third of the price. I said no one would know the difference. Mr. Hays looked me in the eye and said, "Oh, but the owner would know". That has stuck with me for the last 58 years and I have tried to live life in a way so as not to flaunt what I have but to just respect my good fortune when something good comes my way. So UHHers, lighten up. Respect each other, give recommendations when asked, and don't come down on others for their choices. (If you are wondering about the cheap prices for Rolex Watches -- while I worked at the jewelry shop the US went off the gold standard. One day gold was 37.00 an ounce, the next day it was like 387.00 an ounce!)

Those are precisely the reasons why I seldom give comments.
Even when i really meant it in good faith, it is often not appreciated and may even project bad vibes.
Also I am not privy with the situation when the photo was taken that my comment might be totally useless. An example is my location, where no photos are allowed of many places and people in general without approval & consent. Hence some of my photos are not really what i want them to be.

So, I often just give a thumbs-up. Thats me saying "I like what I saw" or "I agree" with the post.
More thumbs is me shouting ang saying "very well done".

If I do not like it, well, the poster liked it enough to share. No reason for me to shoot it down.
Unless they specifically asked for comments, help or upinion. Well, I do not really want to shoot it down and genuinely trying to help, but i'm not into flowery words. SO SORRY, I DONT WANT TO BE MEAN, just being straight to the point with whats in my mind according to what I have experienced before, or how I solved a similar dilemma.

NO.
It is not the camera, is the photographer behind a camera.
The photographer’s eye is as important as the brand name of the equipment used. I have seen an experienced photographer, Marcel from Miami, a Master Photographer (Coral Way Studio),
purchased a Yashica Mat 124, for $50, in the Bird Road Flea Market, mounting a
120 roll of Vericolor film ion the camera,
and later in the same visit to the Market
saw a little boy dress as a cowboy with toy guns and hat, he took 2 or 3 photos
manipulated the best image in the darkroom, printed a 16x20, which was a Masterpiece and hung in the PPA (Professional Photographers of America),
as a Loan Collection print.
