h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

This first picture of my painting needs te be changed to delete the "waves" in the paper.
So the yellow should be yellow all the way and not yellow,gray yellow,yellow,etc.
I am talking about a rough correction.

I don't succeed in doing it.
I get stuck half the process,and in my condition I cannot keep trying for hours and hours.

I try to work with "Photostudio" and then with the magic rod.

All help in any way is welcome,

Greetings from Amsterdam,

Alfredo

I don't use Photostudio. Does it have a "contrast" adjustment feature? That's how I would approach it first in PaintShopPro. A 25% contrast increase (and no change to brightness) might do what you want (as I just tried that here).

Thanks, I will try.

No I didn't succeed.

In my case, I'm half way.

The stick is o.k.; very good, I must say. It takes the whole yellow area, pure and non-pure.
But combining it with the colour options in the menu is difficult, because it should be rather easy and I just don't know exactly how.

Thanks anyhow for your help.

After using Google, I bought a book exáctly about my photo software.

guess it may help (knock on wood)

It probably should have come with a manual when you bought it - or at the very least had a built-in help system.

If you can select an area by its approximate yellowness, you ought to be able to flood-fill an area by its approximate yellowness. You'd just have to get the settings right for that.

Another approach would be to paste your selected piece into another (blank) canvas/file and then use the remainder as a mask for creating a properly shaped yellow area in yet another canvas/file, finally lifting up that piece and slotting it back on top of the original.

Thanks for your reply.

In the book I bought are described various ways and one of them
atrracted me; cloning.

I very soon wondered why one always should create a colour in the firstplace, while there might be examples in the pictures itself.

Only I did not find the combination of cloning and painting, but after zooming I dotted here and there the cloned yellow and later on red, and I must say, it shows already much better than the original foto that shows the bubbles in the paper so clearly.

Wonderfull how at h2g2 we can learn from each other and how we try to help each other.

A warm experience.

Greetings. P.S. Probably the picture will be placed in the h2g2 art album with the title Yellow Red one.

Alfredo, the fuzzy patches in the yellow sections of your picture are due to over-compressing the file.

They are called jpeg compression artefacts (or artifacts).

The best way to get rid of them is to go back to an original, uncompressed file and use the 'Save As...' menu to resave the picture as a jpeg with less compression (higher quality).

A search for 'jpeg artefacts artifacts' should bring up some useful articles.

Thanks for your reply.
I'll study the facts, but I think it will take too much effort at the moment. But your reply will of course be saved, because I take it very serious.

By the way, you can earn a 25 euro's = 30 dollars to do the job.
Let me know, íf.

Although, maybe overcompressing might be part of it,
but the painting itself on hard paper really has bumps.

I always have to put all kinds of stones at the painting after I have finished it, to minimize the bumps.

I am still trying to find a way of reconstructing the paper afterwards.

I heard, some people use wallpaper paste and a

........and a ironing board

I just put the first version of the painting at my phlog.

The second one is the changed version.

> "the painting itself on hard paper really has bumps."

Well wet paint on paper *will* cause wrinkles. People used to use board or stretched canvas. Meanwhile, oil-paint has always been lumpy anyway - the texture of brush or knife strokes is often part of the design.

Hey Alfredo, just wanted to say that I'm not usually a big art fan but I really enjoy the picture posted on: Tue 7 Feb, 2006 - 12:19:51 PM. keep up the good work.
