After editing, my pics are heavier

[Monarque1972]

Hi guys!


Maybe this is a little off topic...

When I edit my pictures in my editing software, I save them in maximum quality (my A95 only save them as JPEGS so I can't afford loosing quality), but the files end up being heavier than before. Is it something I should accept in order to keep the maximum quality, or should I decrease the level of quality in which I save my pictures???

Thanks

Are you saving in jpeg again,.. best quality?

Either way,. yes,. you should just except it,. by saving on best quality you are probably adding a little "weight" but it won't add much ,. (maybe another 3rd or so to the originals file size? ) and it's better to do that than to recompress hwere the quality loss can be significant.... :(

It's a small sacrifice of just little more hard drive space.

,.. and consider this,. those of us shooting in RAW are starting out with an 8-9 MegaByte file,. and when we resave in Photoshop to a 16 bit tiff,.. we gain A LOT of WEIGHT!
Like blowing up to 48 MegaBytes!!!!!!!!!! :shock:

Thanks a lot. Your answer is really appreciated !!!

Monarque - I am not sure if I understand what you are saying, but I am wondering whether your editing software is saving your pictures in another format? For example, my Jasc Paint Shop Pro can save them in a .psp format which takes many times more disk space than the Jpegs they were when they came out of the camera. This would also happen in Tiff format. But whenever I'm done editing and resave changes as Jpegs even at the highest quality, they are ALWAYS smaller in file size than they were originally. So I suspect you are saving your changes in some other format. Even at best quality, when you resave Jpegs, I don't think they will ever be quite as large; at least I've never had that experience.

Hi Bodryn!


First off, I have a Canon A95 which, as you may know, can only save pictures in JPEG format.

So what I do is just load them in my editing software (paint shop pro or Photoshop), edit them (I don't bother converting them in a lossless format such as TIFF because when I edit a picture, I always do it in one single session), and then, or course, I save them as maximum quality JPEG again.

And after, the edited picture is always heavier than the original one, even if it's directly JPEG to JPEG.

I've found a few threads about that on the net and it seems to be normal, but I'm no expert!!

I've found on the first resave there is minimal loss of quality but the file size is a little smaller, from then on the file size stays about the same but some of the mid tones are thrown out... I always shoot in RAW, not an option for you I know but save my files in either Tiff or PSD because I often save layers something you can't do in Jpeg... This enables me to change an effect without having to start from scratch evry time... Just thought it might be worth you thinking about that and blank DVD's/CD's are cheap enough if your hard disk space is limited

It's definitely "normal"

I see it all the time. If you open a jpeg that was saved in PSCS's "6" quality for instance,. edit it,. and then resave as "10" quality,. the resulting file will allways be larger than the original.

Been there done that - I always save stuff that is in 12 quality, cause harddrive space is no object with 160gig SATA seagates going for 90 bucks brand new :-D, unless of course the images are going on a webpage, then I'll opt for a 6 or 7 quality
