Hi, I am new to DSLR and Photography and seek to learn more on how to improve my photography skills.
Please give your valuable comments on the this shot that I have took. ![]() The image was taken on the following settings on a EOS 450D with Kits Lens 18-55mm: Shooting Mode:AV Shutter Speed: 0.3 Aperture Value: 5.6 Exposure Compensation: 0 ISO Speed: 400 Focal Length: 55mm The image seems okay on a smaller scale. However it looks grainy when scale to 100% (4272 x 2848 RAW). Why is that so? Is it due to my settings or Camera shake? Or is that limitation of the kit lens? Thanks for viewing. BlackCloud ![]() |

Probably ISO noise. Try using lower ISO.

This is especially evident when shooting RAW, as it does not pass through noise reduction.

Thanks for your prompt replies, I will bear that in mind regarding the ISO.
![]() But, will reducing the ISO cause the image to be darker? |

Yes as the sensor's sensitivity to light is decreased. To counter this increase exposure length

I am looking at another image that I took, which I have used ISO 500, TV:1/25, AV:4.5 and focal length at 22mm. It did not looks as grainy as my HDB shot. Can It be the amount of sunlight that plays the part? Thanks. BlackCloud ![]() |

Exposure length is the same as shutter speed. Increase it by a few stops.
ISO noise becomes more and more visible the longer the exposure and the lesser the ambient light. So if you are shooting at mid day, even at ISO 1600 the picture should be relatively noise free(except at the areas with dark shadows). |

Not Exposure compensation. exposure TIME. It's basic photography maths, I suggest you read the newbie's guide to photography on here. But a quick idea: Let's say at ISO 400, you can take the shot at 1/4 second. You reduce the ISO to 100, or 1/4 of the former sensitivity. Logically, you must compensate something by 4x to make up for it... Like exposure time, which then becomes 1s.

Increase means LONGER, not shorter. 1/100 is shorter than 1/30. Please read the newbies guide. A lot of hard work went into it to answer the exact questions you are asking.

Maybe I'm being ignorant abt these; but as long as I know I wont be printing out my pictures for any size bigger than 5R; I wouldnt be too bothered with it.
Most times, my pictures will be uploaded in JPEG and in around 300 - 400 kb files; enough for the monitor and the eyes. Noise are negligible.. unless you'd go around blowing up pictures and pixel - spotting lah...

What are you trying to capture?
HDB flats (are they?), lights? Geometric shapes? twilight sky? Put the technical aside for the moment, they are secondary to the intention in the picture. Right now all I see are nondescript shapes and lights in a twilight sky. It could well have been an accidental shot, or even, in Clubsnap's most dreaded term, a snap shot. |

No. Your math is all wrong. 1/120 is faster, not longer. By reducing to 1/12- and ISO 100, you're only getting 1/8th of the original exposure. The correct math would be to increase shutter speed to 1/8s.

So do you think you were successful? And even so do you think there are better ways of capturing such a scene? Can it be made more interesting? Maybe something that even attracts the attention of people who have been seeing such a scene all their lives? Or perhaps there are none, then do you think that this is a worthwhile picture at all?

![]() Maybe the angles? or something that I can look out for? Maybe you guys can help suggest given the scenario what might be a better way of capturing it? Thanks. ![]() |

Try borrowing a book on landscape and architecture photography from the library.

- You have already the impression that the picture lacks something. That's good and it's the right starting point. Be critical to yourself. Main question is always: what do you want to show? What's the purpose, main subject, message / story? Have you achieved the target?It's the same as with the maths about exposure time above: check for existing information and compare with your own knowledge. |
