| # exposure-bands | ||
|
|
||
| generate successive bands of gradually increasing exposure. | ||
|
|
||
| This is useful when testing and prototyping image-rendering transform and | ||
| you need to evaluate its render against different exposure of a same source. | ||
|
|
||
|  | ||
|
|
||
| # design | ||
|
|
||
| Be aware that to be dynamic as possible the node generate the exposure bands | ||
| on different frames. This implies also having tcl expression using the `frame` | ||
| variable which can sometimes lead to unstabilities. | ||
|
|
||
| # adding dynamic text on each band | ||
|
|
||
| It's possible to add text indicating the exposure value of each band without | ||
| manually creating a text node for each band, however it's a bit tricky: | ||
|
|
||
| - Go inside the node | ||
| - Between the 2 internal nodes add a `ModifyMetadata` node | ||
| - add a single `_bands_exposure` key | ||
| - as value of that key put the tcl expression `[value parent._exposure]` | ||
| - Add a `Text` node after the `ModifyMetadata` | ||
| - in the message put the tcl expression `[metadata _bands_exposure]` | ||
| - configure the Text node as you wish | ||
|
|
||
| > Why using a ModifyMetadata node ? | ||
| This is the only hack I found so Nuke properly pickup the band exposure for | ||
| its correct frame (remember the tool use the frame-range to work). | ||
|
|
||
| > [!TIP] | ||
| > If you are using the tool for evaluating image rendering you probably don't | ||
| > want the text to be affected by it, so you will have to put an OCIODisplay | ||
| > node or whatver you use for your image rendering before the text node but after | ||
| > the first internal exposure node. |
