Perte de qualité en exportant un raw en jpeg

[Xavier Flahaut]

Bonjour, je retouche mes raws sous lightroom (z50 sigma 150/600) et quand j'exporte en jpeg taille 1200px 300ppp j'ai une perte de qualité (mauvais piqué) alors que si je change la taille de l'image sous photoshop et sauvée en jpeg c'est net. Une idée ? Merci 

Cordialement Xavier

Show us a screen capture of what you are seeing. (Use the "Insert Photos" icon to include your screen capture in your reply; do not attach files).

Are you viewing the sharpness at 1:1 (or 100%)? If not, you can't really judge sharpness.

No I save the jpeg nuder PS no more LR which lost in quality (this is a lost of time)

If you're trying to send images by email, that doesn't work.

To insert a jpg, use the Insert Photos button in the toolbar.

To attach a raw file, drag it to the attachment box at the bottom.

In the LrC Export module are you applying Output Sharpening as shown below?
