Ergonomie … disons “perfectible” dans Photoshop

Pour un logiciel mis sur le marché en 1990, et vendu la modique somme de 840 euros, on pourrait s’attendre que Photoshop ait résolu les petits problèmes d’ergonomie qui empoisonnent la vie des utilisateurs. Et pourtant, sur Photoshop CS6…

  1. D’abord un peu de contexte pour comprendre le problème: une image Photoshop est composée d’une série de calques, un peu comme des dessins sur papier calques superposés. On voit les calques en dessous à travers les parties transparentes des calques supérieurs. Un calque d’ajustement (adjustment layer) est un modificateur qui permet d’ajuster la couleur (teinte / saturation), la luminosité ou le contraste, sans modifier l’image elle-même. Par défaut, un calque d’ajustement affecte tous les calques placés sous lui. Jusque-là, tout va bien.
    Là où ça se corse, c’est quand on veut que le calque d’ajustement affecte non tous les calques inférieurs, mais un seul calque (par exemple: on veut donner une couleur rouge à la robe de la petite fille sans lui donner l’air d’avoir subi un coup de soleil).
    On commence par faire des essais basés sur le bon sens. On fait un click droit sur le calque d’ajustement: dans le menu contextuel, pas moyen d’affecter l’ajustement à un seul calque. On essaye d’ouvrir le menu Calque: malgré une longue liste, pas moyen non plus. On essaye de glisser-déposer le calque pour la placer en dessous ou par-dessus du calque à modifier, ou la faire décaler vers la droite: toujours rien.
  2. La solution doit se trouver dans la documentation, mais je ne l’ai pas découverte. Il m’a fallu consulter l’ami Google pour savoir comment faire: cliquer sur le calque d’ajustement et faire Alt – Ctrl – G… Pas plus compliqué que ça… Il suffisait de le savoir. En attendant la prochaine utilisation, quand on se souviendra qu’il y avait une combinaison de touches, mais qu’il faudra re-consulter pour se rappeler lequel.

Autre exemple plus simple: une des constantes de Windows (et, j’imagine, d’Apple) c’est qu’un glissé-déposé (drag and drop) d’un fichier vers un logiciel permet de l’ouvrir dans le logiciel. Et bien… dans Photoshop 6 ça marche pas.

Personnellement, comme logiciel de création graphique, je préfère Fireworks, du regretté Macromedia – racheté hélas par le même Adobe – ou bien Corel Painter pour la simulation des peintures acryliques, huile, aquarelle…, des craies et des crayons conté.

    Sinon on positionne le curseur entre les deux calques et on appuis sur ALT. Le curseur change et y’a plus qu’à cliquer.

    Pour moi un outil graphique doit pouvoir se passer d’une doc de 500 pages. Les racourcis c’est bien, mais ça suffit pas. Toutes les tâches doivent être au moins disponibles aussi par les commandes de menus et/ou ou un menu contextuel.

    This is probably evidence of corruption, not financial incompetance. Remember, McCain was one of the “Keating Five”. While he was never directly implacated in the criminal aspects of Charles Keating’s business, McCain had no problem whatsoever associating with (and vouching for) the crook.
