Default Canon 450D manual mode

just started with DSLR n only using the kit lens. anyone have any idea how to take in manual mode? whenever i set the shutter speed to like 1/x-xxxx the exposure is always "-2". no matter what aperture i set. is it due to the kit lens? or some other settings which i missed out?

There is nothing wrong with the kit lens.
Means at that shutter and aperture setting, your exposure will be under. i.e. not enough light. A few things you can do.
  1. Lower shutter speed
  2. Open aperture
  3. increase ISO
  4. Add light (flash)

As the name of the mode suggests, it allows for manual exposure of the shot rather than let the camera decide what is the correct exposure.

Even if you use the semi-auto mode like Tv and Av, if there is not enough light, the shot will still turn out underexposed.

turn the top dial on the right to "M"

Push the ISO to say 400 (larger no will compensate dimmer condition but get more grainy )

speed set to 1/80 (lower speed will compensate dimmer condition but swiming fish will not be sharp)

F set to smaller number (smaller = bigger/larger aperture size = more light enter the cam)

try to play with the 3 parameter.

do post some result here. it will be easier to pin point the problem

thanks bro. will try that out. probably it was due to my ISO also. i only set to 100 or 200 nia. no wonder i can only c my tank lights very dim when i set to live view mode. i was only playing ard with the shutter speed n aperture nia.

some better shots out of ard 10+ shots taken:

Aperture: f/4.5
Shutter Speed: 1/25 sec
ISO: 1600


Aperture: f/4.5
Shutter Speed: 1/30 sec
ISO: 1600


Aperture: f/4.5
Shutter Speed: 1/20 sec
ISO: 1600


Aperture: f/4.5
Shutter Speed: 1/20 sec
ISO: 1600



comments pls. the color of the fishes still look quite dull to me. could b due to the bright surrounding ard the tank during day time? when my exposure is 0 some parts of the pics look too bright. the exposure that i got for these pics r ard -1/3 to -2/3.

The light meter in the camera is just a guide. When shooting subjects that are black or dark, it will have the tendency to over-expose. Likewise, when shooting things that are white, it will have the tendency to under-expose.

You can set the parameters to increase the saturation, contrast and sharpening. The default setting might not work best for you all the time.

To get better result, you should try to get a much light as possible. that's why for most of us we will go for remote flash.

FYI, most of my pix were taken with ISO 200 or below, speed at 1/200 and F at 8 or above.
