Re: [Gimp-user] black & white
No problem - I agree with you that using varied procedures to do things produces a better understanding of the tool as a whole. If education is your goal, then I think that already, you have learned a large number of options to convert an image from color to black and white. To get even deeper into image manipulation, you might try using the selection tools, including the quick mask (button in lower left-hand corner) to enable working on only a selection layer, as opposed to the whole image. Something I also just realized about the Photoshop tutorial you referenced that might make more sense in GIMP is to use multiple layers as your "image history". You can use layers in one or two ways in the GIMP. Naturally they good for distinguishing between parts of an image. For example you might have one layer containing a field, and a second layer containing a small house, placed on top of the first layer. Also using layers, you could create copies of your image as you make changes, in effect creating your own rudimentary filter stack (like those found in Adobe/Macromedia products.) At any rate. Keep asking questions. Keep experimenting. The GIMP is one of the most powerful image manipulation tools in the world. The only thing that might make it appear less is the lack of pre-programmed plugins, I suppose. But it incorporates all of the granular functionality of commercial tools easily, like Photoshop or Illustrator.

Re: [Gimp-user] black & white
Last attempt... ...of course between the layers that GIMP has and the Channels, I'm sure that it is not impossible to emulate adjustment layers. You should note that each layer in the GIMP is fully functional. Some things you can do with them include applying a filter, like dodge, burn, multiply, or overlay, which works non-destructively on the entire layer. I'm guessing from your response, Norman, that none of us were answering correctly, that I didn't look at the Photoshop tutorial very well that you referenced in your original question. Looking at the tutorial more closely, here is what I'd suggest resembles the tutorial in your first post, but it requires two less layers than the four given in the tutorial for Photoshop: 1. Load the photo in question 2. Duplicate the "Background" layer by clicking on the Duplicate (or copy layer) button in the Layers dialog 3. Click on the "Background Copy" layer in the Layers dialog 4. Adjust the Mode for this layer by clicking on the Mode drop-down box and selecting Hue (near the bottom) 5. Right-click on the image 6. Select Colors > Hue-Saturation... 7. In the Hue-Saturation dialog, move the Saturation slider down (in a negative direction) until you get the black and white levels you desire. That's as close as I can get to the same thing. In my opinion the GIMP's is much more straight-forward - namely have filters on discrete layers, rather than Photoshop's having a filter stack. Nathan I attached a zip archive containing the three images I worked on using the technique described above. And a fourth that is only slightly desaturated. I couldn't get these to you, so here are some links to them - they are GIMP 2.4 XCF files, so you'll see all of the layers and such when you load them in GIMP: http://www.mediafire.com/?j0gdzitgg2y http://www.mediafire.com/?xgaipryzm31 http://www.mediafire.com/?pgywazmwgeo http://www.mediafire.com/?dgzi99gmjos The original stock photograph used is attributed here: http://www.sxc.hu/photo/981014 Daniel Hornung said: > > There are no such things as adjustment layers in GIMP... -- Nathan Lane Home, http://www.nathandelane.com Mirror, http://nathandelane.awardspace.com ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
Re: [Gimp-user] Preview window
There is also the "navigation" window under the dialogs menu, which will give you a small window that has a "zoom square" that shows the level of magnification you are using. You can also drag this window around on the larger image and it will change the view in the main canvas window. I have used both this and the new view window mentioned by saulgoode to work on zoomed in areas. Very handy. --- Lap1994 <[EMAIL PROTECTED]> wrote: > Gimp have a preview window that appears when you zoom the image?
