In reply to:

RumpelHund: Thanks for embracing and putting into a historical context what we see today (again) in photography.

Like that positive approach, looking forward to the images!

Indeed, there is nothing new under the sun, just some things that have been forgotten.

Wildbegonia: Love these type of challenges were art and photography spiral around each other like two long strings of DNA. Great challenge Mark, congratulations.

Thank you very much. It is a joy for me to see what people submit and vote for in each challenge.

ws1967: too many photos for a fair voting

The rating system is designed so that you can vote for as few images as you desire:

"The final ranking system assumes that not all people will judge (or necessarily even see) every image. As images are shuffled during judging (to ensure equal exposure), better images will still receive more high-value ratings, pushing them to the top in the final ranking.”

"We chose a rating system over a ranking system because it frees you (the judges) from having to judge every image. Voting on only a subset of images in a challenge has no negative impact on the fairness of final result so take it easy.”

I keep my challenges open so that everyone can participate if they so desire, although I do put a limit on the number of photos per person. As dpreview’s comments above indicate, you don’t need to vote on every image, as it doesn’t affect the fairness of the final ranking. So far we tend to get a good number of votes per image on average.

I’d recommend that you simply vote as much as you like.

Hm, beavers can weigh 80 lbs or more. Let’s say that “small” is small enough to hold in one hand.

On Still Life challenge (1 comment in total)

CLARIFICATION:

A still life is a collection of small objects that you arrange and then photograph. This is mainly an exercise is composition and lighting.

There are some essential elements here: you have to do the arranging, and the objects have to be small enough for you so that you can make numerous re-arrangements until they look good to your camera. This is key to the still life genre -- you take ordinary objects and arrange and light them in a way that is pleasing.

Please don't submit objects that were pre-arranged by someone else. Most of the art in still life is you making the arrangement.

Still life pictures traditionally have multiple objects arranged on a table. While you can have a well-composed photo of a single object, that isn't quite what the genre of still life requires.

A still life is purposefully restricted. Because some parameters are fixed, you are then free to explore other things, such as adjusting the placement of your subjects and your lighting.

In reply to:

rowanberry: I don't feel I can do justice to these pictures when there are so many of them to consider. Up to four entries per user is just too much - this is probably why a lot of similar images turn up. If someone is really keen, he or she will get a picture in in time when there's a limit of, say, 100 - 150. If you agree - or disagree - plese say so.

I generally like wide participation in challenges. I do know that I am frustrated when a challenge fills up too quickly. I like multiple entries for the similar reason that sometimes it is hard for a photographer to determine which particular image is best. Often it is quite surprising and gratifying when one particular photographer's work is all rated quite highly on the same challenge.

Now this does make it much harder for conscientious voters who want to vote for each entry. I've heard this a number of times. The voting system appears to be robust enough to handle voters who only select a subset of images to vote on.

Notice: I've gotten a number of complaints about images of architectural interiors. These are acceptable for this challenge, even though I do plan on having a future challenge dedicated to interiors.

In reply to:

mwfrost04: Can I just clarify..
Are you accepting images of single animals only or are small groups/packs acceptable?

Cheers :)

(Apologies. I also posted this in error as an entry comment rather than a challenge comment)

Groups should be OK. The voters will decide if it works or not!

In reply to:

Joe Pineapples: Far too many entries! To do a decent job of voting on such a large set of photographs would take hours. Surely it would be more sensible to limit the number of entries, and then run the challenge again in a few weeks time?

Joe,

In dpreview's voting system, any given voter can rate as few or as many images as they want. They use Bayesian scoring which takes account of voting irregularities. You can vote for as few images as you please, and it won't affect the validity of the final ranking. Viewing and voting on these images ought to be an enjoyable pastime and not a drudgery!

I typically want these challenges to appeal to a broad audience and to allow wide participation. I know that I get frustrated when a desirable challenge fills up quickly.

Remember, it isn't necessary to vote on each image.

In reply to:

DK Baker: So, the vertical sensor plane rule is more of a suggestion?

What I have under the "Additional rules" sections are mainly hints for beginners. There is not enough room for these in the challenge description section. Feel free to ignore these suggestions if you think that you can get a better image otherwise.

In reply to:

JeanPierre Martel: What you're calling "Additional rules" don't look like rules but tips. Can we use compact cameras (like micro 4/3) or not ? Is it against the rules of this challenge?

Yes, they are tips, and not rules. I'd think a micro 4/3 would work quite well with this.

On Sunday morning Cali Gull in the Wildlife Photography challenge (0 comments in total)

Greetings, I disqualified your image of a seagull because it does not meet the main rule of the Wildlife Photography challenge: "Submit a photograph of a large animal in the wild." However, I will soon host a bird photography challenge, and perhaps you could enter this image then.

On SQUIRREL OF CAPITOL HILL in the Wildlife Photography challenge (1 comment in total)

Greetings, Because of the main rule of my Wildlife Photography challenge, I unfortunately disqualified your image of the squirrel. "Submit a photograph of a large animal in the wild." However, I will soon host a small wild animal photography challenge, and you may want to submit this image to that challenge.

In reply to:

needforspeed009: Does it have to be in the wild, or are pics from a zoo acceptable as long as it's not obviously from a zoo?

"Submit a photograph of a large animal in the wild."

No zoos, but large parks would be OK, where the animals freely roam, and there are no safety barriers between the photographer and the animals.

Birds and crocodiles are acceptable.

However, this is mainly a large animal challenge. I'll be hosting upcoming challenges on small wild animals and birds later.
