I frequently render all audio in a project to a .wav file. I can then import the rendered file, and use it to replace all existing audio files. Initially, I simply null all of the existing files, but, once I am sure I do not need the original source files, I delete them from the system. That gives me one audio file to adjust and to go into the render process.
BTW, I have never seen an audio render take very much time, but, then again, I always render the audio and video separately for DVD Architect.

The only thing I know of that you can do is put the camera on a tripod with a remote shutter release. The type of blurring you describe happens because you cannot hold the camera steady enough during the time the shutter is open. If you are trying to rescue existing photos, heavy sharpening will help a little bit. Perhaps something like Photoshop Elements will do that, but I don’t think you will be able to remove all the blur.

Based on what I saw, Photoshop uses the GPU for things like Warp, Liquify, Paint and other special functions. Perhaps you use these things for 200-300 photos at fashion shows or weddings. If so, perhaps a GPU will give you a speed boost. I suspect most photographers are like me. These functions are used rarely when there is a very special need. For the vast majority of photos, they are irrelevant. However, if GPU was used for all raw processing, or all rendering of an image, there would be a more substantial case. I did not see this mentioned in the specs I saw for functions which utilize the GPU. Perhaps someone has a link to a more comprehensive discussion of this topic?

Take it from me John, there is no 15 second delay and one does not sit for long periods of time waiting for it to kick in. I just tested this yesterday. The only reason to consider a graphics card for Adobe processing is if you are using Premiere Pro. I’m guessing most of us here are not in that category.

A yellow caste can be removed using a color curve. You can reduce the color for the two colors that make yellow (red and green), or you can increase its complementary color (blue). You will need to figure out where your yellow color lies on the tonal range of the color curve for best results.
However, your description sounds like you may be seeing noise rather than a color caste. If it is noise, the color curve probably will not remove it.

John,
I did try the filters with my ancient GTX 660. Warp, liquify, paint and other filters work just fine, and, to my eye, they produce instantaneous results. I see no lag at all when I use them.
-
Hmmmmm, so that means Photoshop cannot render certain filters if you do not have the appropriate GPU? Or, perhaps it takes a fraction of a second longer to render the image using the CPU? If the latter, then I’m still having trouble seeing much advantage to the GPU when I’m working with one image at a time.
Since I have CS6, I will try liquify and warp to see if they work, and if I notice any delay.

I may be out of touch, but I’m having trouble visualizing how Photoshop will benefit significantly from GPU on a video card. In Photoshop, you are working with one image at a time. You will not see any delay in rendering that single image, or a variety of adjustment layers applied to that image. Conversely, Vegas deals with 30 images per second (in my world) with all of their adjustment “layers”. There is no comparison. If there is a significant benefit to GPU, I think it comes on the Vegas side of your processing.

It not only allows you to select each channel, it allows you to copy the settings for one channel to the other two channels. Then, you can make additional changes to the curve for each color. I frequently use this ability to adjust colors like yellow which utilize two of the three color channels set to the same values. It is a very powerful capability built into Vegas.

Yes, I think that is your problem. When I increase volume after denoising, there is a point where I can again hear the noise. Also, when I run the denoiser more than once, it is not unusual to begin hearing things that do not sound right. I try to get all of my levels fully adjusted before denoising the audio. I usually can apply a compressor to that result without adverse consequences.
