problem with conversion from TIFF to JPEG

Post by dudijr »

Hi guys!

As I wrote in a topic, I've got problem with convertions from TIFF to JPEG. XnConvert changes the colours and final jpeg is different than TIFF.

Could you support me ? Should I use some srgb profiles ?

Thanks!!!

Could you upload an example JPEG and TIFF showing the problem -- 1MB limit for attachments, or upload to a file hosting service and provide a link?

Could you also attach a screenshot of your XnConvert 'Actions' tab?

Both images you have linked to are JPEGs... Are you able to upload a link to the orignal TIFF, or is it too large even with a lossless compresion option such as LZW? Edit: Or has the format possibly been changed after you uploaded the file?

Is the colour change you are experiencing visible to you between the two JPEGs you have uploaded

Is the JPEG with the larger file size the original TIFF saved in another application??
Could you also attach a screenshot of your XnConvert 'Actions' tab?
Are you selecting any actions -- it is not necessary to select any -- or just using XnConvert to save the input TIFF as a JPEG?

or

and screen of actions:

You can see the difference also in my previous post - thats the problem.

Thanks for support!

The input TIFF is CMYK and XnView can only open it as an RGB image:

Could someone advise on the optimum settings to use in the XnConvert 'Actions' tab to maintain the original colours?
