Hello friends !

If I start painting, I usually use 800x800 and 300 dpi. Hmm, but if I want to paint more details, I have to zoom in .. and very often I have to use the zoom factor with 400%.

But if I do that, I get distortions on the lines... hmm, here you can see a screenshot:

Is there a soluton, where I can avoid this and get a fine antialiasing ?
Iīve tried to set the dpi higher, and higher... but it doensīt matter if I work with 300dpi or 3000 dpi.... hmmm..

thx for every little help,
bernhard

Hi brox,

When you change dpi but leave resolution at 800x800px the thing that changes is printing size. I see two solutions for your problem; either work in greater resolution (e.g. 3508x2480px, which is horizontal A4 at 300dpi), or use smaller brushes. Or you can go wild and do both :D.

On the other hand, if you see it only at 4x zoom then just paint your detail and zoom back :shrug:.

Thank you Michal !

Yep.. I think I will change my resolution.
Thx a lot,

Okay, I changed my resolution and tried it again... guess what ?
It doensīt work....

itīs the same.... and now ?
I think than itīs the hardware, or ?

let me know what you think about,
thx,
bernhard

you shouldnt worry about dpi, dpi only matters before you print it.

the actual number of pixel have nothing to do with dpi (dots per inch) and pixels dont get affected in any way no matter what dpi you put in. dpi only defines how many pixels will get printed on the paper in every inch, or something like that.

try painting on a 10 x 10 pixel canvas and then try a 1000 x 1000 pixel canvas. you will see the difference.

i am not sure what you meant by its the hardware but i dont think it has anything to do with your hardware either.

As long as you stay inside the computer you can leave dpi out of the picture. That just has to do with print resolution.

If I understand your question right, you are asking if there is a way to get 400% zoom without aliasing. To that the answer is no you can't, 400% zoom is always 400% zoom regardless of resolution. To get more detail you need have a larger resolution image where 100% in photoshop shows a smaller part of the entire image.

Hope this makes it a bit clearer for you. Otherwise, feel free to ask again. I didn't get it the first time either http://forums.cgsociety.org/images/icons/icon7.gif

Okay, so yes, the dpi is for print only.

Well, I was wondering... because, I want to paint details, and for that reason, I have to zoom in as example 400% ... but it doesnīt matter if the resolution is much bigger....

Hardware:
Yep, I thought my monitor sucks, and itīs not possible to get a better view...

okay, but it seems to be impossible to get no distortion in painting with a zoom of 400%...

or is there any solution that will fiox that problem ?

Thx a lot,
bernhard

Use illustrator...

No really, there isn't any solution to that. That's just how pixels work. The more you zoom the bigger each individual pixel gets.

I think Zwempha gave the best solution...
at 100% one pixel will appear as one pixel of your monitor
at 400% one pixel will duplicate four time on your monitor....so it look like it

so use high resolution, that (at 100%) you can control the small things.

i think you are getting pixels confused with vectors.
when you start with a 800 x 800 pixel canvas the number of pixel is fixed, ie. there will be 800 pixels horizontally and 800 vertically.

what you are refering to as distortion is not distortion, its just magnified pixels.
when you magnify 400% you are looking at a pixel 400 times its original size. so no matter what resolution you are you will always see magnified pixels at 400%.

so, like everyone else already suggested, you solution is:

create a new file with high enough resolution (something like 8000 x 8000 pixels), keep your magnification to 100% and paint.
