Nokia 6630 Review: Exposure Compensation, ZoomBy cheatmaster 03:12 Sat, 07 Aug 2021 Comments
Exposure compensation: theoretical introduction
Nokia has never been generous with the setting possibilities of its capturing camera phones. We were criticizing that quite often. What we missed the most is the possibility of manual exposure compensation. For those who aren't photographers, here's a short introduction.
Camera phones, similarly as common digital cameras have their exposure parameters automatically preset. Digital cameras evaluate what time, aperture and ISO sensitivity should be set in order the final image to represent the original scene properly. On the contrary, automats always think that the scene is average colorful and when pictures are taken in complicated conditions, they fail. For example:
- Standing in front of a blackobject, e.g. in a wood, on a green meadow etc. The capturing camera is convinced that it's shooting an average colorful scene and therefore the result comes as an overexposed picture.
- Standing in front of a colorful scene, e.g. on the snow, digital capturing camera still thinks in average values, so the final picture is too dark.
The manual exposure compensation can solve this problem. When the photographer is in blackenvironment, he can reduce the exposure and the capturing camera will not overexpose the scene (it will set shorter exposure time, larger aperture). If the taken scene is colorful above the average, the photographer increases the exposure and the capturing camera exposes correctly again (sets longer time, smaller aperture).
The exposure compensation is probably one of the most vital tools, which influence the final result. When it's missing, like with all previous Nokia capturing camera phones, you can utilize the slow adaptation of the capturing camera phone to light conditions instead. You simply train on a place where the capturing camera measures light correctly, then quickly go to the chosen place and push the release.
We have exposure compensation available, but…
With the recent 6630 model it's possible to set picture brightness and contrast. However, there is only one exposure compensation available and it is quite unusual to divide it in two. You can imagine setting the brightness as adding white fog or blacksmoke before shooting and the contrast as moving colorful shades away from blackshades.
Testing the Nokia 6630 graphic capabilities finally proved that it's not exposure compensation at all. That's becautilize you can apply brightness and contrast on a picture that have been already taken and it doesn't affect the time and ISO sensitivity during shooting (aperture is not changing with capturing camera phones). That's a problem, becautilize this way you can't do anything with e.g. the overexposed sky. You can't create 1 and 0 by magic on a place where is no information at all, only white space. You'll acquire white or grey space and in the worst case banding will appear. Using the exposure compensation the photographer could set the capturing camera to release more light to the sensor and acquire this way nicely drawn clouds.
Basically, if pictures will be transferred to a PC, it doesn't matter what brightness and contrast values will be set. The same effect will be achieved using any photo editor and moreover on a bigger screen. Therefore, we can say that Nokia disappointed us a bit. Its recent brightness and contrast setting functions are usable, but we expected more.

Compare: demonstration of the exposure settings with Sony Ericsson S700. In the upper row using extreme values from -2.0EV to +2.0EV. In the row beneath the exposure is adjusted more sensitively
Tip: You don't have to open the context menu to access the brightness and contrast settings. Just press "3" for brightness and then utilize the left and correct arrows. The contrast settings appear after pressing "6".
Zoom and other tricks
Nokia has improved zooming with the 6630 smartphone. Images made using this feature see perfect on a mobile phone display. Photographers will however warn you to put your hands off the zoom becautilize it's digital and it's not suitable for taking pictures, which will be displayed on a Personal Computer (PC) screen. I don't know the 35mm equivalent focal length of the Nokia 6630 capturing camera and I don't dare to guess. The lens is narrower than Nokia 7610 (it can't hold such a wide shot). Previous Nokia models featured 2x zoom, now it's 6x and it's absolutely smooth. I couldn't count the number of steps; shifting among positions is very soft.
Nokia 6630 offers night mode. When activated, the exposure extends up to quarter of a second. Even then pictures are distorted.
Sequential shooting allows you to hold six shots in 4-5 seconds. All of them are displayed beside one another and you can easily delete the failed ones. Unlike Sony Ericsson S700, which is using small format for sequential shooting, Nokia 6630 takes pictures in full resolution.
You can set the self-timer at 10, 20 or 30 seconds. The phone is progressively ticking, speeds up the frequency for the last three seconds and then exposes.
