As already mentioned there is more noise, all sensors require current to work, as they work they heat up, heat causes noise, so all the time you are looking on the screen to compose your shot the sensor is active, all this time the noise levels are increasing, because the sensor is small it can't dissipate this heat so noise builds up!.

With a DSLR the sensor is not active during the composition this is done optically, the sensor is only using current and warming up when it is actually taking the picture, so less noise!. Add to this the fact that the sensor is physically larger and requires more energy to start getting noise you can see why DSLR's have much lower noise!.

The main drawback with compact cameras is shutter lag, you press the shutter and 1/10th of a second (on the best models, some are much worse than this) later it takes the picture!. This rules out taking pictures of children, pets or any action picture where you want to 'capture the moment'!. With a DSLR you press the shutter and it takes the picture, there is a slight delay while it stops the lens down to the aperture you set and moves the mirror out of the way, but that's measured in milliseconds and is always constant!.

Holding a camera at arms length (with the camera shake that it brings), looking at a screen which on a bright day you can't see clearly are hardly conducive to good photography!.

With DSLR's you can change the lens so you can mount it on an astronomical telescope and photograph the heavens, or at the other end of the scale a microscope and photograph bacteria, and everything in between!.

On top of all this the real advantage of a DSLR is that you are in control, you can set the aperture (in aperture priority mode) so you set the depth of field!. The shots where your subject 'pops out' from a blurry background are possible, the large depth of field from a small sensor and the fact that the camera will decide which aperture to use makes this kind of shot very difficult on a compact, even on those which do have an aperture priority mode!. You can also use a fast lens with wide aperture to make this effect even more dramatic!.

The difference between a photographer and a snapper is that the photographer will know what they want the final print to look like and uses his/her knowledge to realise the result they want, for this you need to control the camera, not the other way round!. But you also need the knowledge and experience so there is a learning curve to getting the best out of a DSLR!.

DSLR Pros:

1) The sensor!. The average DSLR has a sensor that is from 8 to 15 times larger than a compact camera!. The exception is the Sigma DP-1* compact which has a DSLR-size sensor!. A larger sensor means larger pixels which improves image quality and performance at higher ISO settings!.

2) Interchangeable lenses!. You can change from a wide-angle to a macro to a long zoom which gives you more creative control!.

3) Lens quality!. Lenses for a DSLR are higher quality, using superior glass in their design and construction!.

4) More creative control!. The larger sensor makes it easier to control depth of field!.

5) Better and faster analog to digital processor!.

6) Faster response - shutter lag measured in milliseconds rather than in seconds!.

DSLR Cons:

1) Size!. You can't drop a DSLR in your shirt pocket!.

2) A steeper learning curve!. To master a DSLR will require more effort and study!.

Compact Pros:

1) Easier to carry about since you can drop it in your pocket!.

2) Easier to use!.

Compact Cons:

1) A tiny sensor!. Unfortunately, manufacturers have exacerbated the problem by stuffing ever more pixels into a tiny space!. This causes more digital noise beginning at ISO 400!.

2) Shutter lag!. This is the time, measured in seconds, between when you press the shutter release and the camera actually takes the picture!. It can be alleviated by pressing the shutter release 1/2 way to let the camera focus but you still miss a lot of pictures!.

3) Pictures ruined by camera shake!. While some compacts have Image Stabilization built-in, many do not so you have to research which models do or don't!. Then there's the type of IS used - some cameras boost the ISO to increase shutter speed and that degrades your picture while other cameras use a system that moves the sensor!.

4) Often limited creative control!. Compacts range from simple point & shoot models with no user control to models like the Canon G9 that rival a DSLR in terms of control!. However at that level the price edges close to that of a DSLR and you still have the problem of a tiny sensor!.

My vote goes to the DSLR!.

* One major drawback to the DP-1 is it has no zoom lens!.

Hi there!.!.

SLR definitely produces more lively, more colorful output, more details, and u can create any photography effects as u wish (combining different shutter speed, different diaphragm and ISOs)!.

But, for traveling around, it's quite heavy!.Www@QuestionHome@Com

Truth be known, if two pictures were shot at the same shutter speed, the same f stop, and the same ISO, no one in this group could tell the difference!. Www@QuestionHome@Com

noise mostly for the images, smaller sensors cramming pixels into less space

in terms or tool usage the dslrs give more control if you desire it
