I am new to photoshop. was watching a tutorial about creating TIFF Bitmap from JPEG. there the instructor creating Bitmap directly and his greyscale is already ticked.
but when I was creating mine is not. I have to convert the colorful image into grayscale and then into BItmap.
his version is photoshop 2015, mine is photoshop CC 2021
I wanna know is my approach correct? I mean manually ticking grayscale?
plz ignore if it sounds ridiculous. I am a newbie. I am confused so am asking.
@NeverLookBack I'm here now. In short the difference between your document and the instructor's simply is that your document is in RGB and the instructor's is in Grayscale.
@NeverLookBack You can't convert directly from color image to bitmap mode. You have to first convert to grayscale.
@NeverLookBack Btw: "Ticking grayscale" or rather selecting a color mode using Image > Mode is sort of a shortcut. What really happens when selecting "Grayscale" (or RGB or CMYK) from the menu is that the document is converted to that color mode using the settings specified in Edit > Color Settings.
So it can be a bit misleading as a lot of people think you can simply "switch" color mode to for example CMYK without specifying a color profile. But in reality a color profile is always used when switching modes.
But it doesn't look very important in your case as the graphics you are making look neutral anyway? I mean your document is RGB but all your graphics seem gray.
@NeverLookBack It's important! But you don't have to do much math yourself. In Illustrator and InDesign you can select an image and read the Effective PPI.
I think you can somehow save a conversation, not sure how. You could click left of a sentence and click "permalink" and save that. Or you could later search the room for yourself saying "resolution".
