C'est quoi une photo de qualité

Bon j'ai compris ce qu'ils veulent comme photo de qualité. En gros il leur faut une photo proprement contrastée (pas cramée pas sombre) avec une netteté parfaite partout et tout net.

En fait les mecs sont des pixel peepers : ils regardent pas les photos à la taille de toi ou moi soit du 1000px par 800px. Non, eux ils regardent à 100%. Donc tu as intérêt à descendre ta résolution de photo avant de poster.

Coucou Gormé: OK, je vais voir si j'ai des trucs du genre sous la main. Tiens, c'est sympa, un allemand vient d'arranger ma photo de filtres dichroïques (neutralisation du fond, recadrage).. plutôt sympa quoi :) --Démosthène (talk) 15:10, 20 July 2014 (UTC)

Je vais tenter des photos macro de composants élec en les pensant pour. On verra ce que ça donne. En attendant félicitation pour miroir dichroique :)Gormé (talk) 15:30, 20 July 2014 (UTC)

About Ocean City

Je viens d'uploader une nouvelle version de ton fichier "Bay of Ocean City" en rectifiant (je l'espère) les petits problèmes repérés par Cccefalon... Ceci en guise de bienvenue. J'ai été aidé à mes débuts par d'autres collaborateurs de France et d'ailleurs et j'essaie de faire la même chose avec les nouveaux arrivants... même si mes productions ne sont pas toujours exemplaires ! En fait, tu as peut-être besoin qu'on t'explique une partie des nombreuses abréviations utilisées couramment sur ces pages... et, surtout, ce qui me semble encore mieux, qu'on te suggère quelques moyens de supprimer les défauts les plus fréquents. J'essaie de te faire ça dans une dizaine de jours : je dois m'absenter une semaine au cours de laquelle je n'aurai sans doute qu'un accès internet très limité (ou inexistant). À bientôt donc. Bien cordialement. --JLPC (talk) 21:35, 25 July 2014 (UTC)

P.S. : ce soir j'ai mis une note sous ton camion US : le mur de droite n'est pas parallèle au bord de la photo et, sur la page des QI, on redresse les verticales ( parfois même un peu trop !)... mais la retouche est facile à faire.

Merci JLPC !

C'est très sympa de ta part :) J'apprécie vraiment le geste. En fait, je suis assez néophyte en photo, j'essaie de m'améliorer parce que j'ai beaucoup de choses très intéressantes à photographier en ce moment (je travaille dans un labo de physique atomique, d'où mes photos de labo). Si tu as des conseils concernant le traitement des photos, je suis preneur: c'est vraiment quelque chose que je connais mal. Jusqu'ici, j'ai utilisé les fonctions archi-basiques de Gimp, mais je reste incapable de corriger proprement les problèmes de bruit ou d'homogénéité du fond, par exemple.

Merci pour tout, en tout cas ! :) --Démosthène (talk) 21:51, 25 July 2014 (UTC)

If the light wasn't so adverse, maybe one could argue about the exposure on the face, but in this situation, the light control is admirable. --Stegop 20:08, 27 July 2014 (UTC)

Bonjour, saurais-tu m'indiquer la marque ou la référence de la résistance variable BNC que tu as photographiée ? Je crois qu'elle me serait très utile. — Preceding unsigned comment was added by 98.252.136.158 (talk) 00:14, 08 February 2016 (UTC)

Bonjour, Concernant le résistor variable, il s'agit d'un VT1 de chez Thorlabs. Un équipement typique de labo. https://www.thorlabs.com/thorproduct.cfm?partnumber=VT1
