Im tired of trying to figure out these photo grading algorithms.... I have a pic that has 59 wins and 43 losses yet the image score is only 511.

Hello Alec, please check this blog post: http://blog.pixoto.com/2012/09/why-wi...

In this article it is explained why images with similar win/loss ratio can have different score.

I hope this helps.

Ok, That makes sense but what determines if an image is amazing I have seen so many photos that mechanically are not very good but photo shopped to death then , mis categorized with good scores that stick. I have seen photos that are absolutely stunning in the 300 to 400 range. What are you using to determine what is a good photo and a bad photo to begin with? This is more curiosity than anything. I am having too much fun with this site but it is making me nuts when I have a photo flirting in the 690 to 720 range for 85 image duels and end up with a 640 or a picture getting to 598 and ending up with a 540 because it lost the last few duels with pictures that are obvious digital enhancements.

Hi Alec, we allow extensive use of Photoshop or other post processing techniques in all categories.
Please check category descriptions page: http://blog.pixoto.com/category-descr...

Maybe it would be best if you check how Pixoto works here: http://www.pixoto.com/about

To answer your question what is used to determine what is a good image, here is quote from above link:

"...Pixoto members will choose a winner for each duel, and images that win will then be matched against tougher and tougher competition. The results of the ImageDuels are translated into a proprietary ImageScore and displayed on Leaderboards for the category and subcategory that they are competing in. The higher the ImageScore the higher up on the Leaderboard the image will appear..."

I hope this helps.

If you are allowing photo shopping in all categories do away with the digital art category then. Also. You are telling me now that Image duels are what determines a great photograph to begin with? Doesnt matter anyway, eventually this whole thing is going to boil down to who has got more skill with a computer than a camera.

When someone creates a "photograph" of something that never existed in real life, then it ceases to be a photograph. It becomes graphic art.

Why do photographers risk their lives venturing into war zones or at the top of mountains to take photographs? It's because that's what people want to see.

I understand that it would be impossoble to have a rule that says "You can use Photoshop a little but you can't use it a lot." You can't be a little bit pregnant. Either you are or you aren't. Either Pixoto allows post-processing or it doesn't.

What gets me is why someone with professional levels skills wants to come to a site to compete almost exclusively with amateurs. It's like Michael Jordan wanting to play against the a high school team.

Hi Lou!
Exactly. Well said. If that was a round a bout compliment pointed at me ...Thanks. Fits you very well too. What the hell are you doing here????Most of your stuff Ive seen is really good right on point. Like I said in my earlier post its mainly just a fun thing for me. That and I have so many pictures boxed up at the house from over the years that nobody sees. Its a fun way for me to share some of them.

It was in no way directed at you in a negative way. Amateur doesn't mean poor skills. It means you have a day job. I just got a DSLR in May. I've spent a lot of time with my camera. It's helped me get better, but I'm still just an advanced beginner. There are lots of talented people on here and I'm not disparaging anyone. There are also people on here who earn their living with their cameras. It seems like they could get validation and feedback from the people who pay them for their skills, rather than anonymous Internet people.

Still, in all honesty, most of my complaints come from an inner jealousy. If I had advanced Phtoshop skills, I would use them. If I lived near a zoo with tigers that liked to splash around, I would photograph them. I suspect this is true of my fellow whiners - a term I use affectionately.

I hate the over use of photo shop, if you were to stop the use of it all the top winning people would become the top losers, Myself I like to let the camera do the work, if you know your camera and you study the instructions and learn just what you can do, you can create great photos without the use of enhancement software. 95% of my photos are as they came off the camera, the only thing I may do to any of my photos is a minor exposure adjustment, but apart from that nothing.
this is a good example of a photo shop photo, take a good look at the car there is no driver, and the wheels aren't spinning.

This is in Transportation/Automobiles when it really should be in digital art.
This car has been used 4 times with 4 different backgrounds.

This is so frustrating, like the crazy scoring system they use here, I think it should be you get 10 points for a winning vote and say 5 points for a losing vote, you have say a maximum of 200 duels, then say the top 50 winners have another 25 duels to determine the top photo of the week, month and then for the top photo of the year the top monthly winners go through a 50 duel run off for each category and photo of the year. don't know what you think but to me it would be a fairer system.

I agree as far as the car images are concerned. This only tempts others or for others to think it is ok to mis categorise their images.
