Went caving with my 2100 and I'm very disappointed in my pictures. Most of my pictures have a round circle on each corner??. I do have a 49mm to 52mm with a tiffen series 7 UV filter. On the 52mm is also a sun shield. I've never had this problem before with my UZI.

The flash also seem to be underpowered for cave photography. Many of my pictures were not sharp and underexposed. Not a good experience.

Why are you using a UV in a cave? And with still another filter besides?

Loose the stepup. They have 49mm filters for the C2100. The more junk you have on the front end, the more vignetting you will get. Can't figure out why you need a UV and sun shield in a cave??? Try without all that stuff and see how they come out.

Pepi,

I see your image in the cave. I'm disappointed too, what a neat place! I agree with the previous advice that those filters and step up rings are causing some vignetting. One other caution is to be conscious of temperature and humidity changes for your camera. I live in the DEEP South USA, where our humidity is outrageous. If you drive to your destination in an airconditioned car (cold camera with NO humidity) and step outside into hot environment with high humidity, it will begin to RAIN inside your camera. This produces fogging on your lens etc.

When I go to the beach, I put my camera in a ziplock bag before going outside. When the camera is the same temp as the surrounding environment, no rain and no fog!

Now go back and take us some REALLY good shots in that cave!

You will notice this effect most when using wide angle. I use a thin 49 to 55mm stepup which allows only one filter at wide angle. Of course you can always crop the corners or clone the area.

Did you really expect to take great photos in the dark? I'm sure you could have done better with other settings if that's what you mean.

Pepi,

The problem seems to be the additional filters which was added
to the camera which cause the vignetting 'round corners' issue.

As for the flash, you can always set the Flash intensity (See
Page 109).

It looks like in the cave, you do not seems to have a lot of distance
for the flash to bounce on and also the surface does not seems
to have much details which may caused the washout.

Remove the filters since you will not require them inside a cave.

What do you guys use to protect your lense? The guy at the camera store said a UV filter will work anywhere. I really did not think the sun shield would hurt, it is not another filter. I used P mode in the cave, what would have you guys used? I think maybe P mode is only good for good lighnting conditions. Man I've got a lot to learn about this camera!

Thanks

Pepi,go out and buy a good quality rubber lens hood.Hoya makes them, http://www.2filter.com/prices/products/hoyamulti.html

when needed you can have it out but when you are at full angle you just pull it back.Costs about $5-15

I have a 49mm UV on my UZI at all times to protect the lens. It does not cause the sort of vignetting that you were seeing. My guess is that somehow the sunshield interfered with the flash if it did not cause the vignetting directly.

You have two things to worry about: focus and exposure. The picture that you showed us seems to be looking along the side of a stalactite. You need a lot of depth of field (i.e. small aperture) to have that in focus. You also do not seem to have a good target for the autofocus there; nothing that it can use to know when it is in focus. You might try pointing at something the right distance away, half-pressing the shutter button to lock in the focus, and then composing your picture (what you can see of it) and finishing the shot.

As far as exposure is concerned, the built in flash will provide automatic exposure control, so it should be OK. Just be sure that nothing is between the flash and the subject that will cause a shadow. At wide angls, the top of the lens can block the flash from reaching the bottom of the image.

Pepi,

That's the great thing about digital photography. You
can learn all you want, preview the images and if it is
not what you want, you can try again with some other
settings until you get what you want. All these without
costing anything more than what you already spend.

I particularly like the EXIF info as it would tell me the
settings I use so I can learn from my mistakes.

Have fun with your Uzi :)

The EXIF Info are the embedded information such as
Shutter Speed, Aperature Settings. Focal Length and
ISO settings in the JPEG and TIFF images. This information
is helpful because it would help those who are learning how
to take pictures about the settings and be able to compare
same shots with different settings.

If you use the Camedia software, click on any photos taken
by the Olympus and activate the popup menu with the
right-most click and clicking on Properties and the tab Details.

Alternatively, when previewing an image within the camera,
press the Info button to get that same information.

Hope that helps.

Sounds like the lens hood is causing vignetting. Can you see this on the LCD? There should be no need to use this underground as there probably won't be a bright light source to worry about!

From what I remember about spaeleology, there are vasst caverns which will just suck up flash light. You'd need a separate powerful external flash to do it justice.
