Hi Together,

I have a question about the JPEG compression on the Canon 400D.

Until recently I thought I had a real good Camera, but then 2 things happened:

1. I shot a picture with RAW + JPEG
2. My friend bought a Nikon 300D
Come to the point, if I look at some of my JPEG pictures, the shadow area and the colors are so bad that I could go crazy.

The RAW Image give me much "realer@ colours.
I made some shots with my friends Nikon 300D and was blown away with the JPEG even with not the 'best@ compression.

Am I do something wrong here or what is it witht he JPEG and the 400D?

I have attached the sample pictures which I'm talking about.

Sorry, I was just realising that I'm not allowed to add files to posts in this forum.

How Can I share with you the pictures I'm talking about?

not sure why u think you are not allowed to attach files. or is it ust cos u are a new member., do a couple more posts and you will be able to.............. off the top of my head im going to ask what lens you were using and what lens was on your friends nikon........ then im going to ask what settings you had on the canon on JPG? as it is very much dependant on settings and glass as to quality. remember RAW has no processing dont in camera on JPG its deendant on how u have told the camera to process it

The D300 JPEG will be better anyway, because it's a refined system, but I think the main problem is probably that with the RAW + JPEG setting on the 400D I think the JPEGs are low quality only, so probably what you were seeing was a small, low quality JPEG...

Attachments are switched off on Pixalo, but you are able to link to Phtoos if under 300K & 1000 pixels.

You have a free gallery here, so upload & share back in this thread

I wouldn't worry too much re 400D, as excellent camera. Should just be a setting wrong somewhere on the camera for JPEG

Have a look at CLPhotos shots to see what a 400D can do :- clphoto Gallery - Pixalo Photo Gallery (caution - contains nudity)

Hi clafra

There's no reason to use RAW + JPEG unless you need a JPEG file to print or transmit instantly. Ideally, use RAW and carry out tonal and colour adjustments before converting to TIFF or JPEG - that will give you the best quality and the most control.

If you shoot JPEG, Canon offers various Picture Styles that affect the tone curve, saturation and contrast of the image. The default 'Standard' setting is not what it sounds to be - in fact it boosts contrast and saturation to give more punch to the image. Choose 'Neutral' for a more natural result.

Although RAW is better, the JPEG output from the 400D should be very good if everything is set right.

I shoot mostly in JPEG with 400d and i am quite happy with the quality,may depend on the lens used or the setting.

Hi All,


thank you for the quick reply.

Beautifull Gallery ( Dani Marie ), I wish I would have made some of this shots ^^

For the JPEG Quality, I can not see a lot of options on my camera other then either a very smotth compression ( shown as a smooth courve ) or a stepp ( shown as solid steps).
I have chosen the smooth courve.

I,m uploading my Image at the moment to my website, I will post the link soon.


My Setting on the shot:

f / 6.3
shutter speed: 1 / 100
ISO 200
Lens: 17.0mm
focal length: 36mm

My lens: SIGMA DC 17-70mm / 1:2.8-4.5

I'm not 100% sure if I have translated the term right as I use German programs....
I hope this helps a bit.

Is there any additional setting on the JPEG compression on the camera?

[Dave Canon]

Are you sure that you are using the highest quality JPEG setting. Also you can set a number of parameters in the camera which, if set incorrectly, may produce poor JPEG results. This does not happen with Raw because you by-pass the camera processing.

Until we can see the images, it is difficult to make a judgment based on the subject. If you take subjects of dynamic range of less than 7 stops you should be able to capture these fine with JPEG but if the dynamic range is much greater (say up to 10 stops) then you will need Raw if you wish to capture all the shadow detail.

Just set your camera on the smooth curve setting not the step and set it for JPEG only not JPEG + RAW. You'll soon see the differance

I have uploaded now my pictures, here the link:

I have and had set the camera to the smooth curve, not the step.
I may have not explained it properly, sorry!

Thanks again to everyone for your effort...

Hi Together,

somethings strange is happening.

I have now replied 3 times with the link to my pictures but I can't see the message in the forum....

Is it maybe not allowed to post a link to a zip file?


@ chris: I have set the JPEG to the smooth curve, sorry for the confusion!

---- Now it is there...

Hi clafra, the reason why your previous attempts to post a link didn't work is because all members with a post count of 5 or less have any posts with links automatically placed into the moderation queue to be manually approved. This is done to prevent spammers and unfortunately effects genuine members like you on occasions.

I have approved one of your posts with a link and removed the others, all your posts from now on should appear without needing any moderation. Sorry for the inconvenience this has caused you
