Edition of 20/08/2026 · Twelve entries A working reference for digital illustration
Twelve entries on making pictures and on selling them: how a painting is built in Photoshop, how a character is designed so it survives being drawn a hundred times, which program suits which kind of animation, and how a freelance illustrator sets a price, writes a brief and keeps a portfolio worth looking at.
Every entry opens with a one sentence definition, then numbered sections. Where a claim can be checked, it is stated so that it can be: file signatures, colour behaviour, keyboard defaults, dates.
1Practice and business
Four entries
- Becoming a freelance illustrator the trade, stage by stage Ref PR 01
-
Freelance illustration is commissioned image making: a client buys a picture made to a brief and, with it, a defined right to use that picture. What separates the trade from the hobby is the paperwork around the drawing, not the drawing. the three stages, and what each one costs you
- Pricing illustration work day rate and licence fee Ref PR 02
-
Two models cover almost every commission: time sold by the day, and use sold by the licence. Mixing them up is the single most expensive mistake in the trade, because a licence fee answers to the size of the use, not to the hours spent. how a day rate is built from your own costs
- Building an online art portfolio what to show, in what order Ref PR 03
-
A portfolio is not an archive. It is a short argument that you can make a particular kind of picture on request, which means every piece that does not support the argument weakens it. the edit, the order and the technical checks
- Designing a logo as a freelancer a mark, not a picture Ref PR 04
-
A logo has to survive one colour, a stamp, an embroidery needle and a sixteen pixel favicon. Illustrators are often hired for marks precisely because of their drawing, then lose the job on reproduction. the tests a mark has to pass before delivery
2Craft: painting and space art
Three entries
- Digital painting in Photoshop a beginner's order of work Ref CR 01 · method
-
Digital painting is building an image from brush marks on raster layers, in an order that keeps every decision reversible for as long as possible. Beginners rarely struggle with the brush; they struggle with the order. flow against opacity, masks against the eraser
- Creating space art in Photoshop the build order for a scene Ref CR 02 · method
-
Space art is astronomical subject matter painted so that it reads as physically possible: star fields, gas, a lit body, a shadow with a hard edge. The order of the build matters more than any single brush. star colour, nebula colour, and the terminator
- Space art techniques: surface and light emissive materials, falloff, passes Ref CR 03
-
Once the scene is blocked in, the work becomes a lighting problem: how a self lit material behaves, how quickly its light dies with distance, and how to keep the passes separate so the grade stays under control. why a lava field tints its own shadows
3Characters and caricature
Three entries
- Designing funny cartoon characters shape, silhouette, flaw Ref CH 01
-
A comic character is a drawing solved for reading at a glance, for being redrawn without drifting, and for carrying a joke in its stance. The design carries the flaw; the writing only names it. the silhouette test and the head count dial
- Hiring a digital caricature artist brief, reference, rights Ref CH 02 · brief
-
Caricature exaggerates what is already distinctive in a face, so the whole job depends on the reference photographs and on a brief that says what the picture is for. Live event work and studio commissions are two different trades. what to send, and what to put in writing
- What shapes a caricature quote the variables behind a figure Ref CH 03
-
Number of faces, level of finish, background, revision rounds, deadline and intended use: those six variables explain most of the spread between two quotations for what looks like the same drawing. reading a quotation line by line
4Tools and formats
Two entries
- Software for cartoon animation twelve programs compared Ref TL 01
-
There is no best animation program, only a best fit between what you are making, what it has to export to, and whether you draw every frame or rig a puppet and move it. the comparison table, by approach
- Flash animation and the SWF file 1996 to 2021, and after Ref TL 02
-
For fifteen years one plugin carried most animation on the web. The format it published, the SWF, is still readable, and knowing how it is put together is what makes an old file recoverable. the dates, the file signatures, the emulators
5What an illustrator delivers
Formats at a glance
Most delivery arguments come down to three questions: does the format keep transparency, does it throw pixels away, and can the client open it. This is the short answer for the formats an illustration job actually uses.
| Format | Kind | Transparency | Compression | Use it for | It fails at |
|---|---|---|---|---|---|
| PSD | Layered raster | Yes, alpha | Lossless | The working master, kept by the artist | Files above 2 GB or 30,000 px a side: use PSB |
| TIFF | Raster, layers optional | Yes, alpha | Lossless (LZW or ZIP) | Print delivery when a flat, safe file is wanted | Web use: the files are heavy |
| PNG | Raster | Yes, 8 bit alpha | Lossless | Line art, flat colour, screen delivery with a cut out | Photographic paintings: the file balloons |
| JPEG | Raster | None | Lossy | Photographic previews and web proofs | Line art and flat colour: edges break up |
| WebP | Raster | Yes | Lossy or lossless | Web delivery when weight matters | Older print and studio tools that cannot read it |
| SVG | Vector | Yes | Text file, gzip friendly | Logos, icons, marks that must scale | Painterly work: it is not a paint format |
| PDF (PDF/X) | Vector and raster container | Depends on build | Mixed | Handing artwork to a printer | Being treated as an editable source file |
| SWF | Legacy vector animation | Yes | Zlib or LZMA | Reading archived Flash work | Anything new: browsers stopped running it in 2021 |
