There is a newer version of Camera Raw in CS5 Photoshop with new features that include new image rendering, noise reduction, sharpening, lens correction, add grain and nondestructive settings applied to RAW file via X. I am still on my CS5 learning steez right now….hope this information helps you become efficient with your work-flow.
Process Version – affects how Camera Raw handles sharpening and noise reduction, along with Fill Light and Highlight Recovery. This can affect the sensor rendering. Click the Camera Calibration tab that is located third from the right and click the Process menu at the top. Process Version 2010 has much better image quality than Process Version 2003. Right click the image to check your version or to update to Process Version 2010.
Noise Reduction is located under the Detail tab which is located third from the left. Obvious noise is the random red, blue and green pixels you see in areas that don’t contain those colors. Raw files the default is 25, it is not fixed it is configurable based on the image ISO setting. Drag the Color slider to the left until you the color noise appear, and then drag it to the right until it disappears. ISO 6400 and greater, the Color Detail slider will help retain the edge detail with higher color noise reduction.
Luminance controls noise that appear as blotches or uneven brightness. Luminance noise reduction even the brightness level in all areas of the photo. It will blur and soften the digital image. Increase the slider until the digital image is too blurry, and then use the Sharpening controls to bring back details in the photo.
Sharpening have not changed in Camera Raw 6 but rendering has. The Raw default amount is 25 is good for images. If you converted older images to Process Version 2010 and have high sharpening applied, the digital image may be too sharp…you make that call. Amount controls the strength of the sharpening applied to the photo. Raduis controls the amount of the pixels affected by sharpening. Detail suppresses the halos caused by sharpening and Masking controls where sharpening is applied. Hold down the Option (PC: Alt) key while dragging the sliders to preview each effect, shows the sharpening applied to the digital image.
Effects is a new tab in Camera Raw 6. It contains the new Grain feature, and Post Crop Vignetting, originally located in the Lens Corrections tab. The Grain feature emulates film. The Post Vignette changed by adding new modes.
Post Crop Vignetting feature in the Lens Correction tab is used to darken the edges of photos and helps draw attention to the subject. Once you crop the image, the effect is lost on the photo. According to Adobe: Post Crop Vignetting has been in Camera Raw for a while but it produced different results then Lens Vignetting and there was many request from users to change it. :Lens Vignetting was superior and Camera Raw 6 remedies this
Grains - set the amounts to 100, Size to 100, view at a lower value. Bring the amount back to 50, 25 and so forth. Next set the roughness to 100 which controls the texture of the grain. To emulate films, add a big Amount with large, rough grains. Adding grains can help smooth images with a lot of graduation and help with banding. Adding grains at sizes greater than 25, blue is added to make the effect look better with noise reduction.
Two Settings under Post Crop Vignetting. The default is Highlight Priority which is similar to to the normal Lens Corrections tab’s Lens Vignetting. Use Amount to set the strength of the vignette and Midpoint to bring it in from the edges. Use Roundness to set the shape of the vignette. To see the shape, set the shape of vignette. To view>Set Feather to 0>set Feather to taste, getting your preferred transition between the image and vignette>Use Highlight to bring back bright objects in the vignette>To protect color in the vignette area, switch Style to Color Priority.
Lens Correction is an issue for photographer in regardless of how much money is spent on the glass. Optical distortion, chromatic aberration or distortion and vignetting that a photographer deal with when snapping their fabulous digital images. Camera Raw 6 introduce a series of profiles to automatically correct these lens anomalies. Lens profiles are available for Canon, Nikon, Tamron, Sigma and Sony lenses. Click Lens Profiles in the Lens Correction tab>click on the Automatic Lab>check the Enable Lens Profile Corrections box. If a lens is available for your lens it will appear automatically. It should correct the distortion, chromatic aberration, and vignette. Profiles can handle lens distortions from simple to severe. You can manually modify the amount using the Distortion, Chromatic Aberration and Vignetting sliders, default is 100.
Manual Lens Correction>click on manual tab>Vertical and Horizontal sliders correct for perspective issues. Rotate helps fix horizons, and Scale lets you remove any gray section that appear when fixing the digital image.
