Layer to grey scale |

Is there any method to convert a layer and its contents to grey scale ? I had to turn image > mode > grey scale to achieve that.
Colours > Desaturate > Colour to grey is not working for me. It makes the whole layer white that shades of grey.

scaling images |

Hi everyone.
I am having trouble with some basic things in gimp.
I can open two separate images in gimp separately. Then i drag one (it is a photo) on to the other.
What used to look like a normal or small sized image covers the entirety of the other one. And it seems like a very high resolution. A small piece of the new image covers the entire first image.
I would think that "scale image" would reform the image to a small size but it changes both images. How can i rescale only one layer or one image??
Also what are the best ways to open up 2 images in two separate layers?
I can choose "open with" and then select gimp from two images and then try to combine them.
Is there another way? If i choose "open with layers" and select an image, the images are sizes that don't work together. So, i try to scale the image, but like i said before, both images change sizes instead of just the new one.
thx. zack

Can GIMP export in tif format without aplha channel? |

A little more than a year ago I posted this topic regarding tif files created by GIMP.
I've now noticed something else about such files which I find strange. It seems possible that this could contribute to some compatibility issues discussed therein. However, compatibility is NOT the only issue.
It now looks to me like GIMP is adding an alpha channel NO matter what I do. For example, I can open a tif format file created by another program and according to GIMP there is no alpha channel. Then I do nothing but export that file from GIMP in tif format. When I subsequently open that file in GIMP it says there is an alpha channel. Furthermore, the newly created alpha channel does nothing. It appears to be completely opaque (i.e., complete white, no transparency). Obviously I don't know what is causing the compatibility problem but I do think I should be able to create a tif file without said alpha channel which would be a format more like what other image editors I'm using do.
Another problem I've noticed with tif files created by GIMP is that they are much larger than what other software would produce for the same image. The tif file created by GIMP is approximately 1/3 larger than it needs to be. The experiment mentioned above where I just opened (input) a tif file and exported it in tif format is that the file grew from 60MB to 80MB. Given that it went from 3 channels (RGB) to 4 (RGBa) that seems like this explains the phenomenom.
What I've been doing for some time now which is quite annoying is opening the files I produce with GIMP using some other editor (typically Rawtherapee), which fortunately is able to open them, and then exporting them again without doing any editing and the resulting file turns out to be about 75% the size of the GIMP produced input file.
It seems like GIMP should be able to omit the alpha channel. I'm hoping I just need someone to explain how that can be done.

Set Default export folder |

For some reason unbeknownst to man or common sense, GIMP insists on export images to the Document folder in windows instead of the Pictures folder. Is there any way to set a folder to be the DEFAULT for exporting.

changing color |

I hope I can explain this without being confusing. On the old win paintbrush 3.1, it had a great feature which I always wanted to get. Not sure if possible with Gimp 2.10. Win PB 3.1 had an eraser feature that would change one color into another color. Example. let's say you have a checkerboard with all green and all blue squares. using that eraser tool dragging it over the checkerboard ONLY the green squares for example will change to another color you want like red the blue would be untouched. Can that be done with gimp 2.10 or even gimp 2.8? If you still don't get what i mean check out this vid at 1:50 into vid it shows what I am looking for.
