Did you use a polarizer? - DPChallenge Forums

So, I'm preparing to go to the coast tomorrow, and I'm browsing through the Seascapes galleries. I keep hearing a voice in my head saying "I wonder if they used a polarzier."

We always remember to write the post processing techniques in our comments, but we always forget to mention if we used a filter. I think it would be a good idea to have a dropdown when uploading the picture in the same area we put our ISO, aperture, etc. The options would be the most common filters: Polarizer, ND, IR, none, etc. I'd imagine it would probably default to "none."

Anyone else think that would be good information?

Not a bad idea actually.

Not exactly vital but it doesn't harm anything.

I think it's a really good idea. Make it easier and maybe it will get more info to the viewer.

I like the idea, especially the part about it listing the different filters, you'd have to make it where you can select more than one in case of filter stackers so maybe not a drop down but just check boxes...not sure.

I always try to include that in the photog's comments box by just typing it in. A pol is great at the beach, esp if you like deep blue skies.

I would carry lens cleaning pads, the kind with alcohol that you can get at "Wally World" in the eye glasses dept. If salt gets on a lens, it just wipes around and makes a mess if you try to get it off with anything dry.
edit; corrected "tay" to "try"

You actually need to "flush" the lens surface with a few drops of water, press to absorb, more water, press to absorb, until it is clean enough to polish up with the pads...

Just my 2 cent's worth. I ruined a Nikkor lens once at the beach, long ago.

yes, although I think he was talking about salt mist, I just put a little ditzel on my ND filter getting a grain of sand off. Luckily it isn't big, but I felt like a newbie.

Only use the polarzier if the bear is really big.

Hey!

This thread is about adding a filter drop down box to the photo upload page, not how to clean salt off a lens, heh.

Focus people!

Thanks Bear M and Dr A. This works too for the heavy gritty stuff. Redneck Lens Cleaner:

You are right Aliqui. My bad.
Yes, take a polarizer. It will help beach pics look a lot more contrasty because there is a huge amount of diffused light at the beach because of the reflective water and sand. There is so much light on sunny days that the light loss will not be a problem, and may even be a plus if you want to open the aperture some to reduce DOF. You can always take it off and shoot naked (no filter) if you want.

Just kick starting this thread back to the top again, re the OP's line about having check-box/drop downs to show what kinds of glass filters were used if any when posting image data.

I feel that it would be helpful to people who are thinking about buying filters, or wanting to know how a certain look was achieved in an image. I am not sure if it would be worth the necessary script writing for the SC to make it happen.
In the mean time, it would be nice if the photog's would type in that info with the image comments as we post the images if a filter that significantly changes the images appearance was used to get the image. I try to remember, and include that info as well as the focal length or zoom setting of the lens used.

The focal length idea has been discussed on another thread a while back, but it didn't get far because there are P&S cameras with fixed ranges, and two standard DSLR sensor sizes, making a 3/2 ratio difference in how the images look with the same focal length lens on the two types of sensors.
I apologize for "funning" up the thread. : )

I subscribe to the idea of having a drop-down box where the photographer can specify if a filter was used. Many times I have looked at a photo and wondered that myself.

Hope there is time to implement it, as it is useful but not vital...

I just took a look at the Seascapes gallery and opened the first photo for each photographer on the page. Of the 13 images I opened, only 2 had exposure details listed (shutter speed, aperture, ISO). Several didn't even list the lens used.

Another feature that may be related to this conversation is having the ability to search for photos taken with a certain camera or lens. Perhaps add some of the details you're looking for also. As it is currently there isn't an option to find photos taken with specifics unless they've been entered in a challenge.

Also you can search for photos by lens. If you go to the page for the lens in Equipment/Lenses, find the lens the header says "Highest Rated Challenge Photographs Taken with Lens (Browse)." If you click browse you can look through the photos taken by that lens. I don't know how to browse by camera, but I thought I saw someone the other day say they did.

No disrespect intended here, but if people aren't inclined to include the basics like aperture and shutter speed, sometimes not even the lens used, why are you so certain that a filter field would be filled out as well?

As for searching for images based on equipment (camera/lens), you can ONLY see photos submitted for challenges. Portfolio photos are not included.

BTW - I'm as guilty as anyone else on not filling in all of the blanks when uploading to my portfolio (challenge entries...yes). Usually I'm just in a hurry. :P
