Change Shutter Speed on Canon 450D?

Hi all,

I love photography and i think i can take a good photo but when it comes to the technical side, well im not greatly in the know there.

What i really want to do is take a photo of water or waterfalls where the water is blurred. I shall link an example, no copyright intended just to show what sort of thing i mean

I know you have to change the shutter speed and been googling how to do that but honestly i havent got a clue and really need a step by step to do it. The lens i have is jsut the basic kit lens that came with it.



Although along with that, i am looking to buy a new lens, i love to take macro shots of flowers. however i want a good zoom lense, just one with great picture quality and a good zoom. although not to pricey, less then 拢300, preferably much less then that.
Change Shutter Speed on Canon 450D?
Right. I have the 450D and i have done a similar shot with car lights.

The ESSENTIAL thing you need here is a TRIPOD.

Once you have your camera on your tripod, you need to change the dial on the top to TV (shutter priority) then, you need to use the wheel to change the shutter speed to 30%26quot; (30 seconds)



Now, you're almost ready, but first set your camera on the timer (left arrow on the body on the camera) to 2 seconds (this is to make sure the camera doesn't wobble when you take it)



Make sure flash is off, and then you take the photo!



Happy snapping :)

I can't guarantee the accuracy of this website; but see link below?
What you're writing about is called %26quot;time exposure%26quot;. Basically it means that the shutter is open over a length of time, be it 1 second or 30. Like this.

If you'll read your manual closely you'll find out where the controls are to make this happen.



Lenses. What you're actually talking about is 2 different lenses - a macro lens and a zoom lens.

I can't speak to macro but the zoom I recommend is the Canon 28-200. The optics are excellent.

Here's an example of what I mean by the optics - look at my son's eyes in this shot and you'll see

how crisp this lens is.

Good luck with shopping.
On a 450D, set the dial to Tv mode. Use the control wheel on the right hand side to alter the shutter speed and the camera will automatically adjust the aperture to compensate. For a waterfall you could try using a shutter speed of one second (1%26quot;). Obviously you can adjust this to 2 seconds or whatever looks best for you.



However you might find that on a sunny day, you still can't get a suitably long exposure because there is just too much light around and the camera won't let you increase the shutter speed. In this case I recommend you buy a %26quot;neutral density%26quot; or ND filter. These cost only a few pounds on eBay. It works exactly like a pair of sunglasses - just limits the amount of light entering your camera, allowing you to expose for longer in bright sunlight.



If you are using the 18-55mm kit lens, I believe this has a 58mm filter thread, so search eBay for %26quot;58mm ND filter%26quot;. They come in different tints, but I recommend starting with an ND8. You might even be able to find a set of ND4, ND8 and ND16.



Don't forget you'll also need a tripod for shots like this. To avoid knocking the camera as you press the button, you could use the self-timer for a very steady photo.



Good luck!
As you've rightly identified you need to control the shutter speed. Now this can be done in two ways, both of which are mentioned in your manual, for future reference you should refer to the instructions.



Method one is through Tv mode, this controls the shutter speed from 1/4000-30s and leaves the aperture to the auto-exposure program. This is the easiest way to control the shutter speed, however you may over or underexpose.



The best way is to use M (manual mode) this hands control of the aperture and shutter speed. However if you're not experienced with the technical side of photography, you need to get a better understanding of aperture, shutter speed, ISO, exposure and reciprocity.



You need to slow your shutter speed down to at least 1 second, during the day this usually required the use of a ND filter or a Circular Polariser. Furthermore you will require a tripod for stability. I would suggest getting a good tripod that lets you get really low down to the ground, currently the Manfrotto 190XPROB has a 拢20 rebate deal making it a very good tripod to buy.



If you want to photograph the typical macro shots, you should really look into an EF 100mm f2.8 macro or Sigma 105mm f2.8 macro, the Canon 50mm and 60mm macro lenses are not really long enough to be useful as all round macro lenses. You must understand that a good lens often doesn't zoom a lot, instead it concentrates on one thing.



Whatever you do avoid the 18-200mm/18-250mm/18-270mm type superzoom lenses because these lenses are too slow and compromise on image quality too much. Also Sigma and Tamron 70-300mm Macro lenses are not real macro lenses because they don't allow for proper 1:1 magnification that defines macro.
Stick it on TV mode on the dial and scroll so that the number is really large (scroll left) you may need a tripod though as the lower shutter speed allows camera shake to mess with ya photo.



in terms of lens i really like the Cannon 55mm-250mm at 拢180
