The former seems to coincide with my experience. I had assumed it "trumped" the latter. (?) I would have to think about how/why "character count" would be significant (barring the obvious correlation that, for a given "angle", more characters means *smaller* characters).
Setting the type "ragged right" actually helps with readability. But, it doesn't "look pretty".
DTP is a lot more "art" than one would think. You *assume* it's just a matter of getting everything to fit on the page and making it "look pretty". In fact, making something that is "easy to read" (i.e., so that it doesn't interfere with the
*content*) can be very difficult.
Knuth (?) commented that once you start designing fonts, it is hard NOT to look at EVERY font that you encounter with a critical eye. I.e., you stop seeing things as "words on paper" but, instead, start inspecting individual glyphs, kerning, etc. The same is true of DTP -- you look at why someone opted for "big caps", or outdents, or...
Always fun to see newbies using dozens of "fonts", colors, etc. Starts to read like: "LeAvE $1,o0o,00o iN a PapuR bAg uNDer tHe BRidgE at 5tH & MaIn iF yOu EVeR wANt tO sEe yOuR..." :>

Too often, this is done for "artistic effect" -- without good reason. It's as if the person designing the publication just "discovered" some feature and is now playing with it (the same holds true of abusing typefaces, etc.)
OTOH, there are times when it can be very advantageous to flow text around a picture -- if the alternative is
*breaking* the text for an insignificant (small) picture.
E.g., in a newsletter I put together for a local library, I was describing a gizmo gifted to the library that would allow them to hang/display works of art from local artists. The "hanger" onto which individual items are hung is insignificant. But, to describe how the "system" worked, it was necessary to include a photo of it. I included it
*exactly* like your example below as this gave it *only* the space it "deserved" yet allowed it to be included.
For an example of this, see the center of page 4 at
formatting link
also note the fancy photos! The software that does this is BFM as far as I am concerned! I'm sure there is a "simple" explanation for how it works but it always amazes me how "one click simple" it is to use! Though I need to learn how better to *take* the photos that it pieces together -- i.e., the room depicted in the cover photo is rectangular! :<
For an example of the advantage of including photos at high resolution, zoom in on the individual pictures of the artworks on page 4 -- you can even see the texture of the "stucco" walls!
(for an example of NOT using high resolution imiages, repeat the exercise for the book covers on page 5!)
[note to Tim (OP): decide if it is worthwhile for your articles to open with a ToC (bookmarks) on the left, as in this example, or not. E.g., I've found that opening a document in "facing pages" mode is usually a *bad* idea -- as the document "always" starts with a recto page ... *wasting* half of the screen! You can also see that *only* the fonts used in the publication are embedded in it -- *AND* that the "special" fonts (e.g., the "display" font used for article titles) are *deliberately* included -- since I didn't expect most systems to have those available]
Note that the way you layout a technical publication differs from the way you layout something like this newsletter. Different audiences, different emotional connections (in this case, trying to create interest *in* the library)
Things are much better with modern DTP tools. In years past, to pad a line to full length, you had to insert *whole* spaces. For fixed width fonts (e.g., courier), this can be "like fingernails scraping on a chalkboard".
Note that most tools will also play games balancing column lengths (if you so choose). Some will even use *variable* line SPACING to achieve this!

My compliments for this newsletter, best I have seen in a very long time if not ever.
xpdf goes to 400%, I can zoom some more by changing to a lower X resolution :-) Yes I see the texture.
Yes I see the jpeg artefacts in Mark Twain's
Yes, when I ever have the time I may try to find a good DTP program for Linux that actually installs (tried some in the past without much luck). At very old age, if I get that far, when all I can do is press a key, maybe I should write a book. Although these days it is probably 'twitter'. :-)

Yea, but I burned my XP disk, as it wasted too much time. So far Linux has always helped me out, did not want to put too much time into that DTP stuff back then, I write my web pages in html with a text editor.

If you actually *read* them (with an eye towards spelling, punctuation, grammar and content), you'll see big "differences".
It seemed "appropriate" to give the reader/viewer that ability wrt the photos. E.g., you can almost read the label on the "hanger"! I had argued that making the on-line version of the newsletter MORE APPEALING than the "print" version could help migrate people away from the print version (which would cut costs). This is one of the things that gave the "reader" more value in this electronic form than its print counterpart.
I didn't hunt down the individual titles and take photos of their covers. Instead, I lifted the images from the libraries on-line catalogue. There was enough detail to *suggest* the title of each book (note they are explicitly listed in the article) which I thought was enough for that "application". (I assembled the document remotely --- while I was attending to some family problems "back east" -- so I didn't have access to any of these physical items)
While I am an advocate of FOSS (though don't run Linux), I am not a zealot. I *gladly* avail myself of the tools that are available under (e.g.) Windows. Especially if they make my life easier or my "product" better!

That forces you to look *past* a photo for the next bit of text. I don't "interrupt" the reader unless the interruption is "worthwhile". I.e., a reader should be able to keep reading and ignore photos, illustrations, tables, etc. if they aren't "significant enough".
For example, I like to try to arrange photos/tables/etc. at the top or bottom of a column so they user can conveniently ignore them. OTOH, doing this rigidly, results in a boring (visually) presentation.
In the newsletter I mentioned (elsewhere), for example, I took liberties with which "articles" were on each page. And, did some significant editing to those articles to cause images to fall where I wanted them.
When I do technical presentations, I try to silently impose a structure on each page so the reader knowws where to look for things. E.g., if I have "screenshots" in the document, then I might opt to "always" put them in the same relative position on a page -- so the user's "muscle memory" directs him to the text or image, as appropriate (without having to "hunt")

I can see the point of that - by reducing the vertical line spacing, you are reducing the area of the large space and thus its visual effect. I am not sure I like it, however - I thing the line spacing change is distracting and the space is still too big.
Sometimes there is nothing that can be done to make the typesetting look good. The answer in a case like this is to slightly re-write the text until you get a good fit - not to massage the spacing to give a slightly less bad fit.
The tool in question (FrameMaker) seems to do a better job than word processors, and does a reasonable job of the hyphenation, but it has a lot to learn from TeX. The typesetter (person rather than program) has missed a few points too - though again, it is typeset far better than most publications these days, and it looks very nice.
D
David Brown
The basic physiological issue here is the time taken to read the line - if there is too much in it, then you have "forgotten" where the line started by the time you want to move to the next line, even if you can still "see" the start of the line.
So both the subtended angle (which is obviously dependent on the reading distance) and the line's contents matter.
It also depends somewhat on the type of text. If there are a lot of long and technical words, it's important that the line is long enough that these are not often broken. But if the text is slow to read, or boring, lines should be short or you will again lose track of the line starts.
Ragged right is certainly better than rampant hyphenation or wildly varying spacing to justify the text. Good typesetters for short-line publications like newspapers will work with the editors to change text to fit, so that it can be readable /and/ pretty.
There is also a lot more "science" to typesetting than most people think. Even if you don't want to use TeX or its friends, I'd thoroughly recommend reading the TeXbook to see how Knuth thinks about typesetting.
I know the feeling. When you've used TeX or LaTeX, and especially if you've read the books explaining the background, it is hard not to think about it. I can usually spot a (La)TeX'ed document immediately - there is just far more attention to the small details than you get with other programs. It is often easy to see when someone has used a professional program like Frame Maker rather than an amateurish word processor, but the difference is not as great unless it is done by a very skilled typesetter. I am often asked to proof-read documents at work - it is sometimes hard to concentrate on the relevant issues rather than glaring double-space errors or font issues.

With (La)TeX, the defaults pretty much always produce a good-looking document. And, if you're not happy with the results, you can always tweak things to make it worse. [At least that's usually what happens when I decide I want to start changing things.]

For HTML, I'd put a reduced resolution/size image "in-line" with the associated text. And, a link *on* the image so you could "click for bigger picture".
[I consider this too much work -- which is why I don't create HTML documents! :> ]
While I despise PDF's, they are an effective way of controlling content *and* presentation.

The only "big" DTP (i.e., hundreds of pages) I've done were with Ventura (starting in the "GEM" days). I could coerce VP to do a lot more "clever" things -- but, it required more hand-holding (though I suspect some of that had to do with the state-of-the-art at the time).
When Corel started mucking with VP (in particular, when they replaced the TEXT files that VP used with "wacko prorpietary format" files -- which were impossible to "patch"), I went looking for a replacement tool (e.g., Quark, Frame, etc.).
FrameMaker doesn't let me play all the layout tricks that VP could be coerced into doing. But, it adds some other capabilities that VP didn't have (e.g., a much nicer equation editor). For small publications (e.g., newsletter, my "notes" series, etc.) it gets out of my way and lets me get the job done very quickly. E.g., most of the time spent on that newsletter (discounting taking pictures, rounding up articles, etc.) was spent editing other peoples' prose (it is amazing how uninspired some folks are as writers :< ) and gluing together the panoramic photos. The actual "publishing" was probably just a few hours.
We'll see what they say later in life (I take privacy issues considerably more seriously than the young-uns)

Looks like a scan to me, page 2 text is not horizontal, grey background, no colors. Yours is a zillion times nicer.
Corel did very strange things, they once made a Linux distro, and I bought it, In that distro they redirected all error messages to /dev/zero, so if something did not work you would not know about it. Was on my system for a VERY short time (hours), before it was replaced by Suze IIRC.

I think feathering is intended for more "artistic" presentations. E.g., "I have a two column-inch box that I want 'THIS BIT OF TEXT' to *fill* -- stretch/compress it as necessary to achieve that goal".
So, in multicolumn layouts, it just looks silly -- you don't want to (usually) "spread out" (vertically) one column just so it is a certain vertical size (there are other tricks that FM will employ to balance the columns without feathering). Instead, you usually want to "synchronize" the text baselines of adjacent columns (otherwise, the visual effect is very unsettling).
Recall that your document is not one long string of characters (with images/tables interspersed). Rather, it may be composed of many *discrete* "flows" (FM-speak). E.g., when I want to past a lengthy bit of code into an article, I create a separate "flow" for that code -- with it's own layout rules. Then, I tell FM which "frames" the flow should occupy.
So, I can start the flow in a 3"x4" box on page 1 and continue it in a 3"x6" box on page 7 (if that made sense). With this in mind, you can see how some publications (e.g., advertisements!) might want to use things like feathering in particular "frames".
You use both techniques. You can adjust the kerning and spacing within lines (and character sequences). E.g., highlight a section of text and then interactively squeeze or stretch the characters within that highlighted region.
The downside of short line lengths -- especially in technical publications -- is that you tend to end up with "big words" (and/or words that are glued together like "and/or" :> ). This doesn't give you many places to "insert whitespace". So, if you *don't* set it "ragged right", you frequently end up with things like: |the counterclockwise rotation| Your only remedy is to let some other word(s) onto the line and hyphenate them (I *really* dislike hyphenation! With narrow columns, it becomes VERY frequent)
Word processors are crap. I have yet to find a need for one
*other* than writing single page correspondence (I do even that in FrameMaker since I don't want to deal with yet another program that does "something similar").
Ah, well... I'll gladly refund the money that I (wasn't) paid! :>

The problem is that rewriting takes a disproportional amount of time. When I write technical documentation, I often DELIBERATELY use boilerplate prose. The point being to let the user ignore the repetitious aspects of the document and concentrate on that which *differs* from one "topic" to the next.
E.g., like consistently-written man(1) pages (you don't even see the cruft parts of the sentences that just serve to provide "proper grammar" for the *MEAT* of the sentence).
When I did my first DTP project, I canvassed the state of the art for tools, texts, etc. In addition to _The TeXbook_ (volumes A through E, hard copy), I have an assortment of texts on the (legacy) printing process, composition, style guides, etc.
Chase down the "before" and "since" links I mentioned in one of these posts to see how "others" have tackled the same newsletter. It's disturbing (in any field) when people *think* something is "easy" just because it *looks* like it SHOULD be easy!
I am always amazed at the various part of my brain that are "missing". E.g., I can't draw a living creature. But, I can draw landscapes, buildings, plants, etc. in very good detail (proper multippoint perspective, etc.). I.e., that portion of a human brain that can draw people is MISSING in my case! :> OTOH, if you were to show me a drawing of a person, I could immediately tell you what was wrong with the drawing and how to correct it!
(I suspect a similar phenomenon explains why so many people can't "design from scratch" -- but can patch 'till the cows come home!)
For me, it is spelling (though I don't use a spell-checker -- to force myself to be *better* at it!). And, particularly, getting names correct (e.g., all of the names of the "sponsors" in that newsletter). Thankfully (regrettably?), I only obsess about it in formal documents...

Sometimes, these tricks can be used very effectively (e.g., one of my "letters of reference" has NO letterhead; the firm's logo is VERY subtly embossed in the paper. Really classy!). But, too often they are abused. Like wearing a plaid shirt with plaid pants -- and a bright yellow BELT! :-/

Um, er, "Black F***ing Magic".
You *really* would have to play with the software to see just how mindblowing it is! Take N slightly overlapping photos. Drag them into the program. Click and you're done!
I climbed on the roof one day and took a set of photos while slowly rotating. It has a "mode" where it will glue them together in a 360 degree presentation (that you can later "scroll" left or right... amazing -- and dizzying!).
As I said, it's probably "no big deal" under the hood. But, to see how much leeway it gives you in *taking* the photos and how well it stitches them together... BFM is all that comes to mind!
I realize there are cameras that will do this for you. Hence my thought that there must be a "trick" that is easily exploited in analyzing the images.

I think you'll find that these cameras have commercial licenses for the same autostitch software. Certainly true with a Canon I used.
