A Question About PS Jpeg Options

Does anybody know if the different JPEG options on Photoshop makes any difference when you use the "Save as..." command.
I have an Spanish copy of PS; but I'll try to translate the different options.
I'm not talking about "Image options"; sure everybody uses maximum quality (12-big file). My question is about "format options".

There are three options:
1- Standard base line
2- Optimized base line
3- Progressive. This one with a selection of number of passes

What is the best? Or simply... What is the difference?

Thanks.

Stil

Oops! I can't believe I made an unanswered question!  eyebrow 
Well, maybe the question is not clear. I'm talking about this box:

Big version: Width: 407 Height: 363 File size: 105kb


Do you choose one option for any special reason or it doesn't matter?

I use std PS setting, not sure which one that is. I have tried the different settings, but I can't see any significant difference between choosing either one of them, so I don't bother changing it now.

I've tried different settings also. I don't see any difference (In fact it doesn't matter, cause I don't see differences between accepted and rejected pics  Wink ).
But I realised, with preview activated, that "standard base line" -first option- gives you a bigger file size. May I think the bigger the size, the better the quality?

The difference between progressive and baseline is the way the image is loaded into your browser. Baseline loads the image from the top down, progressive loads the whole frame, first with a low res frame then adding (progressively) a number of passes (that you specify) until the image is at full resolution. Different browsers will load these differently. The only important setting is the quality setting. This should be set as high as possible (keeping the file size under 1meg for a.net use). The quality setting determines the level of compression used when creating the file. Less compression = better quality.

Save for web is what I use.

Basically so I can see the what happens to the picture as the quality is reduced, plus I was always nervous about saving over the top of the original by accident!!

I have never known if this was right or wrong. Only thing doing it that way is there is no exif data stored if this function is used. It gets stripped on export.

Hi Stil,

Use:
- Calidad: 12 Maxima
- Opciones de formato: Progresiva Pases 5
- Tamaño: Doesn't matter, it just gives you aprox file transfer time according to connection chosen.

With these settings you get a jpg file with best possible quality and corresponding smallest size.

Do NOT use Sav for Web. The quality will not be the best. To avoid over-writing the original, use "Save As" with a new filename.

Martin, I agree with Viv. Save for Web has been said to compress the file slightly. I started a thread about it a while ago and the consensus was use the "Save As" function vs. "Save for Web."

Makes sense, didn't think on any internet purpose.

We all agree Quality should be "12-Maximum" because it gives the biggest file size. According to this, as "standard baseline" option gives an increasing of size; may this option gives an increasing of quality?

Hi Stil,

I think you might have a confusion here. You set the quality of the file (that is information contained in the file) with the "Calidad" setting. With "Opciones de formato" you do not alter quality of the file, but you just tell PS how to compress the jpg file (and thus have as a result different file sizes).

Whatever you choose for "Opciones de formato", the quality will be exactly the same but the filesize might vary (and actually just little).

Hope this helps you.

Intersting question which I had very often when saving pictures in PS CS2.

I always save at Quality 10 and never had a problem here on Anet - those pics which were rejected would've been rejected at Qu.12 too.
