If you like P&S you should be getting a CAM with manual settings not just WB.. Theres more to WB and ISO you know!

My camera does have manual settings and manual ISO.

ya aperture and exposure?

[Daniel The Cool]

ya aperture and exposure?

 

I have EV. Is that exposure? I know I don't have aperture.

[bveguy]

For example: Exposure would be displayed as 1/60 or something like that.

Aperture is displayed as f/2.1

 

But the ISO settings depend on the camera's megapixels.

Keep your ISO at 400 or 800 in the subway. The more ISO, the more grainy your pictures get so if your pictures look too grainy at 800 ISO then use 400 ISO. As for white balance it depends on the station. Use the setting that makes the picture look accurate in the LCD. You don't want really warm colors at a station like Broadway - Lafayette ( when the light is very cool.

but then with the low ISO you will get darker and more blurry shots. I would prefer grainy shots that are sharp versus dark and blurry shots.

Image noise can be rectified, blur cannot.

ok. Thanks Kris. I'm still trying to learn techniques on my Sony. I might take more pics later:tup:

After doing a quick Google search I found that Noiseware Community Edition is still available for free. While not as feature-packed as some other solutions out there, it should serve as a decent tool to reduce the amounts of noise present in your photos. Note that these programs are not usually the type where you should simply "max every slider". They require careful attention to a 100% crop of the photo in question while you find the optimal settings. It is better to apply sparingly than to go overboard and smudge out all the details.

 

Edit: another useful tool for reducing blur is present as a Photoshop plug-in: Gaussian Blur. By applying a sub-1.0px blur to the photo, followed by a light Unsharp Mask, you can essentially "blur out" the chrominance noise* while retaining detail within the photo.

 

* chrominance noise refers to the multicolored spots one sees in a noisy file; the other type of noise: luminance noise, refers to the black and white hot spots present.

I use Paint.net for my photos. It has a noise reducer and it's very effective.

 

I used it also, to add cool special effects to these pictures I took in another thread.

Ah, didn't know Paint.NET had a noise reduction routine. Last time I used that app...well, R32s dominated the during the same timeframe.

With 12 Megapixels, you can bump the ISO to 1600.

[Y2Julio]

What does megapixels have to do with ISO? My D40 has no problems doing ISO 1600 without too much noise.

[bveguy]

By experiment, when I use an 800 ISO on a 6MP camera, it comes out grainy.

When I use a camera with 8MP and a 1600 ISO, it comes out grainy.

But... When I use a camera with a 10.1MP and 1600 ISO, it doesn't come out grainy.

[Y2Julio]

That's due to the sensors. Some sensors handle high ISO levels better than others. Like for example, my D40 at ISO 1600 has better noise to signal ratio than say Joe's D200 @ ISO 1600.

[error46146]

Grainess depends on the sensor size iirc not about the megapixels

 

In theory a smaller image resolution would actually be better in certain situations since you cannot see as much detail and you wouldn't be able to notice the minor imperfections

[bveguy]

Oh okay. The other 2 I tried it with are P&S, while the 10.1MP one is a DSLR with a CMOS Sensor.

[Y2Julio]

LMFAO yeah man, you can't compare P&S to DSLRs.

[css9450]

LMFAO yeah man, you can't compare P&S to DSLRs.

 

Exactly. And with the DSLR, you've got a much greater selection of faster lenses which will minimize the need for those really high ISOs. Worth the money for shooting in the subways in my opinion.

[buswizard]

I don't have an SLR. My camera is but 6 mp. So I suck.

[St Louis Car 09]

Usually auto settings would configure the ISO by knowing which typeof lit area you are in,but its better to use manual to your exact specs.I dont have many indoor pics but i tend to use between 400-800 iso.

[Joe]

Grainess depends on the sensor size iirc not about the megapixels

 

Image noise doesn't solely depend on either resolution or sensor size, but if for a second we imagine that those are the only two variables that we're looking at, it would be wiser for us to say that pixel density plays an important role.

 

Higher pixel density = poorer performance at all ISOs = decreased dynamic range.

 

Lower pixel density = better performance at all ISOs = increased dynamic range.

 

Dynamic range is the full range of tonal values that a sensor can capture. As ISO is increased on a digital sensor, dynamic range decreases.

Nah you`re good.Just as long as you aren`t using a camera phone:confused:
