Serendipitous malfunction of the finger.

[JBW]

I have taken the good advice and do as little saving as possible in JPEG. But until I accidently attempted to load a JIFF file into my blog tonight I had no idea that I could. Here are the two versions. The first is Tiff and I find it brighter, fuller, deeper. How about you?



This morning I played with the scaling. In my eyes 1200 wide gives better definition as well as much quicker upload.

Defo see a difference on my screen B

I'm not really seeing the difference, Brian, although technically speaking the TIFF is not compressed on saving whereas jpeg's are always compressed on saving. For what it's worth, before I took the giant leap into raw shooting roughly 5 years ago I shot everything in JPEG and always saved any processing in TIFF while retaining my original JPEG copy un-processed in JPEG.
By the way, I really like the image. The tear drops just do it for me.

I did out a little extra pp into the tear drop top left. Both SWMBO and myself saw a difference on our screens. I am almost hoping more people will agree with you because it takes nearly an hour to upload in TIFF and only 5 to 10 minutes in JPEG. But then I don't get paid by the hour. Come to think of it I don't ge paid at all.

A slight difference, nice capture.

jpeg from my understanding loses a little more than Tiff and every time you do some thing and save it under jpeg you again are compressing and thus losing more. Nice pic

enough slight differences can make a major difference. If I scale things down a bit more the upload speed would increase.

If Gimp explains it accurately an uncompressed TIFF file is lossless. These flowers are beautiful and offer endless possibilities for beauty.

Nice image Brian BTW very slight difference.

Thinking over the issue of TIFF versus JPEG again Brian (and you may be ahead of me on this). I know you use layers quite a bit and I was wondering if you have tried saving TIFF files with multiple layers or with the image 'flattened' (single layer only). The difference in system resources and therefore save and load time is significant. I always save my finished work on an image file as a single layer (flattened) TIFF unless I have a specific reason to keep multiple layers which for me is unusual.

Okay now you touch upon a void in my knowledge. My technique is to merge all layers before exporting. Would this be the same as flattening?

Brian, I'm a bit confused

If I open the first and second images (1600x1205 and 217kb and 201kb respectively) in the lytebox and scroll between them I see absolutely minimal difference other than the second image has had the highlight very top left 1/5 in removed?

The third image again no difference other than its a 1200x904 and 154kb, and with the highlight.

If you are uploading by Tinypics its a good idea to keep the file size below 1600 as I believe at 1600 exactly Tinypic affects it. 1200px width is a good posting size but I have now standardised at 1400PX on everything.

I wish I could un-confuse you. But you have confused me as well. If tinypics affects anything at 1600 and up then the first two should be different than the last one. When I put all three up on my the 1200 TIFF is the clearest shot, then the large Tiff and in third place is the JPEG.

However not everyone sees the difference. Yet most people in CinC are very good at looking at minute details and differences.

I am thinking that it might depend upon the monitor? Not that some are not adjusted properly but that they all come with subtle differences?

PS. I used URL to transfer the two large ones and the little one if memory serves.

You would think so but the answer is 'not always'. First I must confess that I am only familiar with Photoshop CS applications (although I believe GIMP is similar in many ways such as layers for example.) Photoshop CS6 for example offers options to merge layers or to flatten image where more than one layer is created. Some processes in CS6 generate hidden layers (i.e. Not listed as separate layers) and opting to merge layers does not merge the hidden ones. In these circumstances it is necessary to flatten the image to eliminate any unnecessary hidden layers which increase file size.
I realise this will not help you directly but perhaps it means that in general when using layers or any other 'complex' processing, it may be a mistake to assume that merging layers means what it says.
Perhaps some with broader knowledge of these things can shed some light.

If I may add to Neville’s post?

Flattening and merging are the same only different!

Flattening reduces the entire layer stack to one background layer and is typically only used to output to a final display format. Such as .jpg or .tif.

“Merging” gives the option of merging layers within a layer stack and that is the basic difference. In other words, in, say, a 6-layer stack you can “merge” two or more of those layers into one layer within the stack. But you can’t “flatten” two or more layers into one layer within the stack.

How's that for "clear as mud"?

Either is cool before exporting Brian.

looks like my coffee. Flatten is the final merge and you can merge some layers but only flatten everything.

Yes.

You can merge some layers, or all of them (that are visible) for that matter. You can't flatten or merge invisible layers.

You can only flatten all of them (that are visible) into one final layer.

If you are not confused, you are just not paying attention.
Think I'll go and have a rest now. My brain is full!
