I don't understand why the coordinates for the grid files goes from 0 to 360 and from 0 to 240 (360*240 : ratio 3/2) whereas the image ratio is 4/3. Thanks !

CHDK/Grids Edit

I guess it is because the LCD pixels are one unit wide by 9/8 units high.

Another variation on themes already covered: square / 16:9 / 3x3 guides for landscapes Edit

Basically, these guides are thin lines, the upper ones are black (for contrasting with sky), the lower ones white (contrast ground), and the file has #comments to show how to quickly edit it to make it your own. Put it here as I don't think it's up to a whole new entry, really :-)

Bum ! The # became numbers ...

(I put the "pre-formatted" text tags around it so it appears as it should.)

Grid package Edit

Is there anybody that can provide a .zip package with all the grids on this page?

Is there a way to enable grids in playback mode?

I'm a painter, and having a grid on playback would help composition / copying down an image a lot.

diagonal rule for sx1 is Edit

Hello! Thanks fo everything… And I would like to have a Rule of Diagnals grid for the wide and normal screen of the sx1 is… does it exist? Thank you!

Yes it is fine! I like it. But how do I adjust the LCD centered in the grid?
