Rawshooter 2005 Question

[Steven M. Anthony]

I recently downloaded the free Rawshooter program. Seems to be very nice. But when I enlarge (on screen) to 200% I see a lot of what looks like jpeg artifacts (but i'm saving as tif). When I make the same, basic, alterations to the RAW file in ACR, I don't get the artifacts.

Anyone know what the deal is here? Did I miss something in terms of needing to pay for a better version?

Just wondering.

I had the same problem Steve. In Preferences, make sure the "Replace proxy-rendering with high resolution preview" is ticked. I found I had to close the program and then restart it to make sure the setting changed.

I checked, and it was ticked already. What other preferences are checked on your copy? On mine, the proxy-rendering is the only one ticked.

I assumed that at 200% you are starting to see the pixels. At 100% each pixel on the image will occupy one pixel on your screen. At 200% each pixel on the image will occupy a 2 pixil x 2 pixel area on the monitor so you can start to see the shape of the individual image pixel. By 800% enlargement the pixels are quite noticeable.

Steve, the test is in the converted image, not the preview. Viewing at 200% is a bit over the top and you will see sone degree of stair stepping. The output however is very clean.

[Steven M. Anthony]

Sorry, should have specified--I viewed both the Rawshooter and the ACR files, after they were converted to tifs, in PSCS. The Rawshooter converted file had the artifacts; the ACR converted file had none.

Can you give examples with processing parameters? I do not get any artifacts than pixels and that is pretty normal for digital photos...

[Steven M. Anthony]

I've tried several different settings. But the artifacts show up in Rawshooter even when I just use a +1 exposure compensation; no artifacts with the same setting in ACR.

I don't have an easy internet source to post the examples to--and don't know if there is any other way to show the examples. But the artifacts are stray lines (tiny, but lots of them), both horiz and vert, some are dark, some are light.

[Steven M. Anthony]

And these little speckles show up in the rawshooter preview AND in PSCS when I open the converted file.

I don't have RawShooter on this computer at present, but is the "apply sharpening" box checked in the conversion settings frame (sorry if this is a little off; trying to remember this from the top of my head). I found that the RawShooter sharpening algorithms produced a lot of unwanted artifacts.

[Steven M. Anthony]

Well, the slider for sharpening is set at zero. Is there another place to apply sharpening?

Click the "Batch Convert" tab and see if "Apply Sharpening" is checked, if it's checked try it unchecked.

Click the "Batch Convert" tab and see if "Apply Sharpening" is checked, if it's checked try it unchecked.

That did the trick. The Rawshooter tif is still a little rougher (at 200%), but it's 99% better than before.

Thanks all!
