looks just like an interlaced filter.
1. File -> New. Choose whatever size, 10x10 will be good.
2. Click and hold the selection tool, choose horizontal pixel selection (third option). Select a line. Now, select pure white (R255, G255, B255).
3. Now, choose Edit -> Fill. Choose "Use: Foreground Color" (if it is not already is chosen). Press OK.
4. Now, select another horizontal line, that should be just below the white line. Zoom in if necessary. Choose pure Black (R0, G0, B0) and then fill
the line (Edit -> Fill).
5. Now choose a Rectangular Selection tool, select these two lines (you should make sure you do not select more than 2 horizontal lines). Choose Image
-> Crop.
6. Choose Edit -> Select All. Choose Edit -> Define Pattern (if the option is greyed out, it must be that you have not selected anything. Make
sure you do).
7. Now, open an image you want to interlace. Create a New Layer. Make sure the new layer is active, if it is not, click on it once to make it active.
Edit -> Select All to select the whole image or select of an image you want to interlace.
8. Now Choose Edit -> Fill, but this time choose "Use: Pattern". Click OK.
9. You should now see your image being replaced by alternating lines of black and white. If not, you have done something wrong and you should start
all over again.
10. Finally, in Layer options, choose Layer Mode "Multiply". Your image should now look interlaced.
11. Final adjustments. While the layer filled with pattern is still selected, choose a Move tool and press cursor up or cursor down (once) to find
what suits your picture best. If you want some layers to be normal while some interlaced, just drag the layers you want to be normal over the patter
layer.
