Best way to process photos with photoshop without adding noise to it?

[cosgeo]

I would like to know what is the best way to process photos with photoshop without adding noise to it. My problem is when i try to make my pics more crispier by tweaking them in PS at some point there is noise in the photo @ full resolution.

You actually enhance noise to any photo and not actually create it by photo manipulation. Most digital photos in high res will show some kind of noise, blurring and artifacts over contrasting areas and color gradations.

It is most common to get 'create' noise in an image post applying the 'Sharpen' filter. Try using the 'Unsharp Mask..' under the Filters--> Sharpen menu instead of your regular Sharpen. Use a setting of around 20 to get decent results.

If nothing works you can use a software like Noise Ninja to reduce the noise and make for a much more soothing photo, but beware it will have a smoothened out look but for most purposes, and definitely for the internet, it is a very good option.

Wht is the best time to use the unsharp mask filter. Before you change the color seeting of the image or after you change the contrast levels etc.....

The is one more thing tht ive noticed of unsharp mask recently. When applied to some photos especially with more golden sort of color the photo pixelates. Will post some samples tonight....

Cosgeo ... As a golden rule ... any sharpening should be done at the very end of post processing. There would be more chances of enhancing noise if you do it before.

if u keep ISO during shots at low..(ie u dont boost unnecessary just for more shutter speed)half noise is gone.

if ur camera only produces noise then its another prob.

using a combo of unsharp masks diffuse glows and stuff,u can keep the noise down.its not always that photos should be sharp.glows also can bring different effect and essence to a photo.

One thing you should keep in mind "YOU CANNOT CREATE WHAT IS NOT THERE" click a photo that way, which requires a less PP. If you keep the attitude that WILL DO IT IN PHOTOSHOP, it would certainly not going to produce some great results. PP is just for the sake of very small manipulation and touchups (Atleast I do that way, I would prefer to click another shot rather wasting time on PP)

Exactly the reason I click each and every photo thinking that I would not be axing it under PS. But its kind of inevitable. No one can escape it.

Less ISO means you need a faster aperture, and thats expensive. So in the end its like the perfect balance and harmony of everything together. But sunny I wanted to ask you and everyone here as I havent tried it out yet. Will shooting in RAW help?

I've generally noticed high noise on anything over ISO 600 :(

As far as my small experience know about RAW, shooting in raw helps in:

>> Getting a proper white balance in PP

>> If you have dust on your sensor, Canon's DPP can help removing that dust using the Dust Delete Data Function, so you dont have to mess around in removing dust specks.

>> Some lens dont produce images with good contrast, doing this in Photoshop changes the whole aspect of the image, while you can do it on RAW form very well.

>> Vignetting can b removed.

>> A small rise in Exposure can be done in RAW but going beyond a certain level would result in grainy images.

The above is what I know and do with RAW images. There may be some other benefits of RAW.

Shooting in RAW helps as in... you can work with a relatively lossless format. Working with Jpg is lossy. What I personally do... I shoot in RAW and low quality Jpg simultaneously.

Noise above 600: depends on what kind of equipment you are using!:)

I would like your reviews on this image. Accourding to me it looks very dull. The colours are jst not popping out. Ive changed the birghtness of the image in PS and nothing else. Im using a Sony H50.

Better?

[cosgeo]

Yaaa itz better but we have added a considerable amount of noise to it now.

Nyways would like to knw wht adjustments have you done there.

[Sarao]

Yup, noise is there, that because the original image is compressed JPG with very less data/info into it. Original image can be PPed with much more good results. Changed contrast & saturation.

Click the image to get an enlarged version of it...... Hope tht will help in better results.

Here's my attempt...

You know, your image already have a high level of noise. Enhancing the image would certainly result in more. noise

Well, I also tried my hands on the image...

My advice is to convert your photo into a TIFF right after you transfer it to the PC. JPEGs lose data each time you save the file. And this may add noise to your image after a few saves.
