Panning of the carousel with compact camera

May 27th, 2010

panning carouselI tested an advanced technology with our compact digital camera. It goes very well to do panning with your compact camera if it has manual settings. We have a Canon PowerShot A720 IS, but also our previous compact camera, the PowerShot A85 has manual settings. Panning is a technique where you have a slow shutter speed to say you are exposing for a relatively long period of time while moving the camera as the subject. It requires much practice and take many pictures so you get the picture you want. You may well use a tripod if your subject is moving sideways.

I have a situation where my son goes carousel and he is in shadow, making it possible to expose for a long time without burning out motives or background. The problem is that if you have slow shutter speeds in daylight that you are overexposed and receive a lot of white. I set the camera to TV mode so that I could adjust the time, but when the camera is adjusted aperture and other settings. Here I thought that between 1 / 15 s gave the best results, but of course it depends on what light you have. When you get above 1 / 50’s, you will have to move the camera very quickly to have any effect.

panning carsI took some pictures of adults who traveled with their children in the daylight to show that it quickly becomes overexposed at slow shutter speeds. Here’s how it is that direct sunlight is overexposed but it is in shadow for correct exposure. There is sometimes a fun power to overexpose a little. In this image I have used a dark background as it may be exposed to contrast against.

Photo Tips for shooting with slow shutter speed

May 2nd, 2010

fake depth of field photoIf you are using slow shutter speeds when shooting so you can get fun effects. The article on how to fake a short depth of field with gimp so I used a picture where I have used tripod and a slow shutter speed to get a soft effect of flowing water. You can do this whether you are SLR or compact. You need a tripod or a place where you can set your camera steady.

zoom slow shutter speedYou can also get cool effects by zooming in while you expose. I have earlier told you about how you can use a zoom lens to get the awesome power at slow shutter speeds . This may be enough to test their way and it requires that you have an SLR with zoom lens.

zoom slow shutter speedIf you have a compact camera, you can instead rotate or move the camera while exposing the image to get the cool effect. This image of ferns, I have rotated my camera to produce an exploding greenery.

DSLRTips have a video where he explains how easy you can do and things to consider. It is important to take many pictures to get the right effect. These techniques require training and luck.

Use your zoom lens creatively to create motion in your photo

February 3rd, 2010

zoom pepper lens motionLast fall I experimented with using the zoom on my kitobjektiv 18-55mm for my EOS 350D to create a little movement in the images by using long exposure while zooming. First, I played with a pepper grinder that we have at home on the dinner table. I look to have quite some time and then I will zoom in the image in a continuous motion while being exposed.

The second image I have created two dimensions by creating almost a double exposure by having a slow shutter speed while zoomed in fairly quickly. I also tried to use the train in motion picture to create a little pad, two dimensions motion blurbut have not succeeded in really well. It has thus exposed a long time in two positions, but still moved between locations. I think it’s important to experiment in this way, not least in order to learn this with the exposure and shutter speed. I also think it can make really cool pictures.

It would be fun to see if others have experimented with this or if you go out now and play a little. Please feel free to show what you’ve caught in your experiments. By looking at other ways to shoot, you can learn a lot. Check in our community to be inspired by others. You can also see it applied on my Örnbräken picture.

Which ISO should I choose to avoid noisy photo?

January 16th, 2010

noise iso 1000 olympus cupTo get a fuss-free photo, it requires light, but sometimes it’s bad weather or you’re indoors and do not use flash. Then you can change the ISO setting. I have previously written about the ISO and you’re not sure how it works, you can check there.

I have pondered and experimented a surrounding this myself and it is certainly not easy. If we leave it to automatic mode, it is quite usual that the bad light that the images may be much noise. This also differs the most about in the digital compact and SLR. One thing that controls how noisy the pictures is how tight pixels is ethylene. An SLR is usually much larger area than a compact camera. There is also this that allows compact cameras with excessive megapixels can actually give a turbulent picture than one with fewer megapixels. I have heard many complain that their new cameras actually gives worse pictures than their old did.

Generally, one can say that you should choose the lowest ISO number as possible. It is possible to have a low ISO number with poor lighting on the subject is still and using a tripod. Date when you can increase the exposure time.

Raise the ISO
If you hold the camera with your hand, you may need to raise the ISO’s. Because if you do not require a long time and you get blurred images because you are not steady on your hand. Same here if the lighting is bad, it will require a long time and when moving objects are blurred.

Lower the ISO
If you can increase the aperture and let in more light, you can lower the ISO, it means a loss of depth of field. Use natural light sources such as windows or why not light to increase light intake and thus lower the ISO.

Sometimes you have to use flash or other artificial light to get good pictures when the lighting is bad. Flash makes it possible to use low ISO.

Perhaps the picture does not require that it is razor sharp and are actually okay with the noise. Always try too shoot with as low ISO as possible.

Always remember to check your ISO setting
noise iso 1000 olympus cupI myself have taken plenty of pictures and then when I get home, I have discovered that the ISO is set too high and the images are very noisy than they would have needed to be. One tip is to get accustomed to when you set the ISO to a high ISO is always set it back to a reasonably low. This is a very common mistake. To shoot at wrong ISO.

There is also a noise reduction program that subsequently “remove” the noise. It is a truth with modification. Information is lost and it is always best to think that the noise in the picture is as narrow as possible when taking the picture. Here beside you see how I used a filter in G’MIC to GIMP to reduce noise in the picture above. It is far from good. Details disappear and become blurred. Even the better programs destroy information from the original image.

So my final advice. Think before you take the ISO image to use. Try to use as low ISO as possible just to get sharp images.

Long exposure when camera is still will give sharp images

December 8th, 2009

car tunnel dark place long exposureIf camera is still long exposure will give you extra sharp images. Here i was visiting a working place in Stockholm which is the port for cars north of Stockholm. We was only visiting for a short term and only a part of the place and it was enormous. We had the time and place to work with long exposure since the place was very dark though up lit with lamps here and there.

I tried different techniques and one of the most successful was standing the camera on the railing and thus being able to take long exposures. I should have brought my stative to ensure the long exposure or made a bag out of rice. One can simply make a simple stative out of a bag of rice. Using the rice and bag to make a comfort place for the camera.

The picture was exposed in 10 seconds a very long time. Thus giving the lamps the star shape and the sharpness of the environment. I have parted the photo in two part the mess making the foreground and the tunnel in the background making it an interesting picture.

Show the autumn storm with long exposure

November 17th, 2009

autumn leaf pictureLet your imagination lead you as you paint with the camera and let long exposure give life to the storms. Here i also let the colors in the background contrast against the leaf. The importance of the backgound almost always forgotten, but do not forget the emptiness that almost alway speak to you more than the motif itself.

I chosen a fast lens with a long exposure time, though the opening giving a sharpness to the movement.

Autumn provides a lot of opportunities to test the slow shutter speeds

October 13th, 2009

långa slutartider övergångställe benYou get a lot of opportunities to try slow shutter speeds at autumn. You can now paint with the camera and let the colors work. Autumn gives you darkness enough to try to work with long exposures and be creative. For example, working with zoom and create completely new images.

lång slutartid trädLet the zoom to work while you expose your photo. By rotating while you expose your image and you will get new opportunities to be creative. Pull your camera around when you expose to create motion and force with which you paint with the colors.

ånga slutartider trädIt is definitely a technique you can practice and take lots of pictures to get there just as you want. How to train is very intense. Use colors and let the enhanced picture and use of technology. Let your creativity run wild as you try to create something new.
