How to improve photo resolution?
May 25, 2008 2:06pm CST
I've been taking photos of my nephew using my mobile phone. And the camera only has 2.0 mega pixel resolution making the photo have some red and unclear. Is there anybody who is good in photoshop here to help me to refine the photo resolution and making the image sharp and clear as it is look like in the magazine photo. Any help would be appreciated.

Hello! Mobile phone cameras are really limited in terms of sharpness and resolution. Unless your cam has at least 5-8 megapixels, your photos will be better off. You cannot compare the shots from your mobile phone to the photos from the magazines as they use really professional cameras for that. Mobile phone cams are mainly for documentation and portrait shots purposes. Now if you really want your photos to be clear and take out the redish color (I'm guessing the red eye syndrome?) here are some of my techniques. As much as you can, don't use flash directly to people's eyes, if that's your red color problem. Use the manual mode if it has. Also, for image clarity, try not to shake your hands when shooting as it may cause blurring in the image. Now if you want to manipulate it in Photoshop, you may increase the resolution using the menu imageimage sizetype your desired resolution. You may increase the size but the quality of image will still the same. You can also adjust the image using FilterSharpenunsharp mask. If still not contented, use brightness/contrast levels. There's another technique but this requires several images of the same image, so you might need a tripod or something to hold the cam in place. this is not applicable for portraits though because the objects should not move. Take several photos of your image, using the same settings, without moving. Using Photoshop, sandwhich each photo together while adjusting each layer photo (of the same images you took) with the blending modeto screen. Flatten the image until you get the desired clearness, Hope that helps, if you need more techniques: http://www.quazen.com/Arts/Photography/How-to-Shoot-Digital-Photos-Effectively.121464

I should appreciate your effort for telling me all this and for that i rate you for best response today. And anyway actually my problems is i don't know why when taking photos using 2.0 MP camera phone under deem light there are red dots scattered everywhere around the image. So my idea is trying to smoothen the image and a clear picture out of it. But i have no skills to do it.

Oh ok, thank you! Now I know your problem. The red dots you see especially shot in dimlight is what we call "noise". It is the grainy effect you get when you shoot with high ISO rating (if you're familiar with that).This is also one of the problems of shooting in dimlight. As you can see, more and more camera manufacturers are actually working hard to improve on this. So, the more sophisticated your camera is, the more you can avoid this noise. Anyhow, we can't really avoid this. But when you want to enhance it using Photoshop, the best you can do is using the FilterNoiseMedian. That smoothens out the noise. Or if you want it more sharp, use FilterSharpenUnsharp mask.

Consider it part of your craft to learn about editing. You already have a camera, all you need to do now is to edit it using Photoshop. There are tutorials and instructions on the Internet. You will evolve in your photography when you learn editing too.

Yeah i did searching on the line on many of the photoshop tutorials but none of them specifically solve my problems to increase the photo resolutions. So i was wonder if any of the mylot member have the skills and expertise to teach how to do the best photo editing for low resolution image.
