Suggested order for Upright adjustments
You really want to apply an Upright adjustment early on in the image processing, because unlike most other image edits carried out in the Develop module, the order really does matter. In particular, you’ll want to ensure you apply the Upright adjustment before you apply a rotate crop or manual transform adjustment. If you happen to apply an Upright adjustment after you have applied a localized adjustment, you may end up seeing some shift in the positioning of these adjustment depending on how extreme the Upright adjustment is. As for lens profile corrections, the impact of a geometric correction is not always as major, but it is best to apply these before an Upright adjustment, as a geometrically corrected image can make the line detection work better. With Upright adjustments there can be quite a shift in the way the image is remapped and this can have quite an upsetting effect on some types of localized adjustment. What you may notice is this. If you carry out a test by applying lots of clicks with the Adjustment Brush to add small spots that dramatically lighten or darken, you will find these adjustments map quite well if a subsequent Upright adjustment ends up distorting the image. If, on the other hand, you apply much larger spots, using a large cursor size, you will see some noticeable displacement when applying an Upright adjustment afterward. If you apply a Graduated Filter tool to an image and apply an extreme Upright adjustment afterward, the chances are you will see a big displacement. This all goes to reinforce the point that it’s best to apply the Upright and lens profile corrections early on before you apply the crop, manual transform, or localized adjustments.
