pacha mama photography Posted March 10, 2007 Share Posted March 10, 2007 I just started shooting RAW. I use the UFraw with gimp and everything worksperfectly until the image is converted to photoshop. The picture shows up finein the UFraw screen but once it is opened in gimp, it shows up with TONS ofgrain and noise. Anybody know how to fix this, or why all the noise would showup from no where?

don_e Posted March 11, 2007 Share Posted March 11, 2007 Are you using both on Linux? Link to comment Share on other sites More sharing options...
pacha mama photography Posted March 11, 2007 Author Share Posted March 11, 2007 no, im not even sure what linux is? Link to comment Share on other sites More sharing options...
don_e Posted March 11, 2007 Share Posted March 11, 2007 The gimp and ufraw are common applications on the linux operating system. I'm familiar with how they work on linux, but have not used them on windows. So, probably don't have any suggestions that would work for you. If I open a .crw Canon raw in ufraw and just make a default save, it opens in the gimp as it appeared in ufraw. Are you doing edits in ufraw? What do you mean by "until the image is converted to photoshop"? Do you mean you save a .psd out of ufraw? If everything works perfectly "...use the UFraw with gimp and everything works perfectly", when does the noise appear in the gimp? Link to comment Share on other sites More sharing options...

pacha mama photography Posted March 11, 2007 Author Share Posted March 11, 2007 well first, there is a sort of 'preview/ufrphotoloader' image when using UFraw. There you can mess a little bit with the image with UFr tools(slight curves color corrections etc). But when it is opened up in gimp, (to use all the gimp tools) the image becomes saturated in noise.<div></div> Link to comment Share on other sites More sharing options...
don_e Posted March 12, 2007 Share Posted March 12, 2007 In the Linux version there are several interpolations that can be set for the save. AHD and VNG interpolation can produce very different looking images. The AHD might produce a noisier-looking image. This may not be reflected in the image displayed in ufraw's window, but is applied to the save. The noise is from the sensor, so it is there to begin with. If you can't see it in Ufraw, it may simply be the magnification level of the ufraw image window (which in the linux version is around 33%) compared to the magnification you are viewing it in the gimp. In any event, the noise is from the sensor, and if it is objectionable you may want to test a noise reduction application. Link to comment Share on other sites More sharing options...
don_e Posted March 12, 2007 Share Posted March 12, 2007 Oh...if you were shooting jpeg before, the image processor settings in-camera may have had a noise reduction setting. You will not see the effect of that in a raw capture. Link to comment Share on other sites More sharing options...
