new to photography-question about grainy photos Hi all! I am new to photography and have just recently really begun to try to learn as much as I can! I primarily take photos of my 7 month old with my Canon Powershot a70. I wondered if anyone could answer a few questions. I try to use natural light as often as possible. I am trying to learn using the manual settings but it seems that most of the time the shutter speed has to be so low without the flash that the pictures end up looking grainy. Should I be using the flash or try some other artificial lighting? Also, given that my camera is just a point and shoot would you recommend getting an slr if I want to see more clarity in the images or should I learn as much as I can on this camera first? Thanks so much for your help! This website is fantastic!

Slow shutter speed shouldn't cause grainy photos. What film are you using?

If you are digital, you don't have grain. You have digital noise. We're getting out of my area of knowledge, but I will do my best. At what ISO are you shooting and how big are you making your pictures?

Hi, Kerry, Are you using any kind of image editing program? PS, I saw your gallery, and your little one is adorable!

I just uploaded another one that is a perfect example of what I'm talking about. The title is Grainy pic. Thanks for your help again!

Amanda (sorry I got the wrong name last time), I use Photoshop, also...I don't like technical jargon, so I went out and got a "Photoshop For Dummies" book when I first started using it to help me. I'm using Photoshop 5, which is the book I got, but have you tried going into "filters" then, "noise" and then, "despeckle"? I don't know how the more recent versions of Photoshop are, but that's how I get the noise out of my images. Of course, it does put out a little more blur than I like, sometimes, but for the most part it works for me. Amazon's got Photoshop 7 For Dummies, which may help. :)

I don't know much about the A70 except that it is a P&S camera. I imagine the sensor is smaller than it is in a digital SLR so that would mean your are enlarging the image more than you would on a digital SLR. Therefore, you will get more noise. If you get an SLR with a lens with a larger aperature, you will be able to use more available light.

If I understand correctly from the posts of the DSLR users, you will have to do more post processing with a DSLR than you will with a P&S camera. The results will be better but you will have to learn a lot more about Photoshop. I'm a film shooter (35mm & MF) so I can't help you much there.

If you're getting a 1/250 shutter speed with available light, then the camera is probably raising the ISO speed automatically. Just like on film, high ISO speeds can make digital images look grainy. Kerry, you're right, digital doesn't really have grain, but "noisy" just doesn't sound right. I'll stick with "grainy". Amanda - the bottom line is, if you want to avoid using the flash, try to get more natural light. Move closer to your light source if you can.

I've seen grainy or noisy digital pics and I really don't see it on your cottontail pic... I don't see the grainy one... A great free program is NeatImage which is great for removing noise. Google it - it's a free download and works great. If you can get a book for PS by Scott Kelby you'll really enjoy it. I've read several but they others are all dry and boring - he makes it fun and easy to learn! I have PS Elements 3.0 and his book - It's great...
