Hello Simon Brown, thanks for the quick answer. My camera (sony dslr-a350) can save pics as raw or jpeg but I used only jpeg by now. my old camera (pocket sony cybershot) saved pics as jpegs as well and I had no problem reaching 40k file size with good quality. I coloured in red above some words that you used and I don't understand if you be kind to explain. and practically, what is the best way to compress my pics (or the pic attached) to 40k ? (at the moment I use to do copy/paste before saving) thanks

Hello all members. I already tried to discuss this matter in a previous thread “Compressing pics without loosing visible quality”, I try to be more specific here: Normally I open by photos in paint.net, I crop and resize them to 550*412 pixels, and I save then as jpeg with file size 40k by reducing the quality to about 90%. Recently (or since I have a new camera) I had to go down to 20% quality in order to achieve limit file size of 40k (which is really destroying the photo). Then I had a comment by someone93 who did copy/paste to the picture and had no problem compressing it afterward. I invite you to do the following test and share with me your conclusion. 1. Download and save the photo “original.jpeg” attached here. 2. open it in paint.net and try to save it again in 40k size jpeg. It will probably need a quality of about 20%. 3. now do: edit ->select all -> edit ->copy , file ->new ->paste. 4. now try to save again the pasted photo as a jpeg. probably this time it will be possible to reach file size of 40k with quality of 90%. What is the explanation for this behaviour? Thanks in advance

well I just addopted the Idea of someone93 who mentioned that by copy/paste he had no problem achiving 40k in about 90% quality. So I open the "problematic" photo in paint.net I copy/paste it into a new paint.net file and the problem is gone. see for yourself, I reattach a sample photo here. (to experience the problem you should save it instead of copy/past it) and as for my new camera (sony DSLR a350) I'm still learning it, as it has too many options. but I don't think I'm using any infrared stuff.... :oops:

yes, I've tried the same actions (copy/paist vs. save as) and the results are different. stange things are happening in the kingdom of paint.net... never had compression problems with images from my old camera (though original image and file size are similier. I maybe try to repost my question in a more precise way. otherwize, maybe someone can recommand me a good image compression software ?

Hello someone93, thanks again for your kind help. It drives me crazy, I’ve passed hours on this, I tried to follow exactly your steps, or use other methods for cropping or for cleaning the background, but I always end up with a picture of about 125k (even without text in the pic) which needs to loose quality until 17% in order to reach 40k. Maybe there are some definitions to change in paint.net (I use paint.net v3.36)

Hello somesone93 thanks for your answer, the photo you've attached respond well to my needs: pic size 550*365 pixels, file size less then 40k, and good quality. unfortunately I could not produce the same result. also after cleaning totaly the background. (you can see also my new try on http://bonnielovesclyde.free.fr ) can you please give me more details about the operations you've executed and their order. thanks in advance Amir

Hello Crimson and Survulus I thank you for your quick answers. I've tried you use your advices but I couldn't see amelioration of quality. I use to add small text to the photo, and the text looks really bad. I uploaded an example original photo and the resulting photos on http://bonnielovesclyde.free.fr/ The quality option is not proportional to the file size. The file size decrease rapidly when going down to 70% quality, but lower then that, the file size is practically “stucked” thogh I continue decreasing the quality. I reached 40k at a poor quality of 16%. I think (haven’t tried it yet) to photograph my objects from a bigger distance in order to have more background to cut out, in order to start with less pixels in the first place Regards Amir

dear members I use paint.net to edit, resize, and compress my digital camera jpeg photos. Normally I resize my photos (by: image-->resize) to 550*411 pixels, and compress them to less then 40K (save as-->filename.jpeg -->quality setting) in order to publish them on the internet. with my old camera, after cutting the unnecessary edges, and resizing, I could get under the limit of 40k with a quality of about 90% which practically shows no difference from the original quality. Now I have a new camera with many more pixels (even when I use it in its lowest pixel mode: 3.5M), and in order to get the same results (image size and file size) I have to choose a quality of about 55%, and that visibly damages the photo. So, with my new camera, respecting the limit of 40k, I end up with a poorer result then with my old camera. Is there any manipulation I can do in order to avoid this problem ? Thanks in advance

Thanks Bob. It works ! Amir

Hello everyone I use paint.net to adjust my photos (jpeg), and I save the results as jpegs as well. The problem is that when I open my photos library in thumbnails view mode, they appear without the changes, and I have difficulties to distinguish between the original photo and the adjusted photos. Is there a solution for this problem? thanks.
