Hi,

I hope I post in the right session and it is much appreciated if i can get some advice from you all. I have been requested to send some pictures to a potential client (it is new to me!!) and he asked for Tiff file. However, he gets back to me and said that some of my images are too large even convert to 8 bits tiff, and when he zoomed in on some of them there was a bobbling texture around most of the subjects (heat haze effect). If I can resolve this problem, then he would like to use my images (which is exceptionally excited for me!). However, I don't know how to solve this problem, therefore I would like to get some advises.

I took these photo with a Nikon D7100 with Sigma 105mm OS in Raw, then process in LR, convert to jepg. Jepg to Tiff. The jepg one doesn't look that bad as the tiff.






Thanks in advance.
 
Looking on the smartphone I cannot comment about the effect you refer to but reading your workflow I think you are perhaps introducing errors!

From processing the RAW if the client wants a TIFF why are you creating JPEG and then converting that to the TIFF?? Even at highest setting the JPEG will be lossy with this potential to compression artifacts which might be expressed/visible in the conversion to TIFF.

Try going straight to TIFF and see whether the helps?

Best of luck with the sales:)

Thanks for the reply and advise!! The reason was that I never thought anyone would like to buy my photo, so I only converted them into jpeg. when the client approached me and said he wanted to tiff file, I just converted it from jpeg to tiff. My bad! I would give it a try to convert it straight to tiff.
 
You are basically exporting a lower quality file then trying to make it higher quality. It's not gonna work like that. Straight to tiff from the edited raw.
 
How are you getting a 45MP image from a D7100? The first and also the butterfly on your flickr are some 8000 x 5500 pixels?

When he says "heat haze", is he referring to the out of focus backgrounds, or something else?

The up scaling has ruined the sharpness at 100%, I can totally see how it looks like heat haze at that size. You need to export in the original size for a start.

(The above is a screen grab at 100% from Flickr to highlight the effect)

Hi Graham, Thanks for your reply.I have no idea how do I get a 45MP image and on the properties of the image of the butterfly it shows 8288 x 5428 pixels. Sorry for being dumb, but I don't have a clue. My workflow: shoot it RAW in D7100, import to LR, process (crop most images), export to jpeg.

I think he means the image detail blown out when zoomed in.

They don't look like heat haze to me, I have some shots of birds taken with a lot of heat haze in 46c heat, if you want me to post them later to show you...

Hi Joe, to be honest I don't totally understand what he means about the heat haze. If you don't mind, I would like to see your heat haze photos so I can have a better idea to figure out what it is. Thanks for your reply.
 
Over processing.

This looks like excessive sharpening and detail enhancement to me with a lot of masking set. Some JPEG artefacts too.

Everyone should be forced to print something at A0 once in a while... it would make them seriously re-consider their processing workflow.

Why are you developing from LR as JPEG, then converting to TIFF? Why not develop from LR into TIFF and have that as your master copy, and make JPEGs from that? Developing into JPEG first is losing quality. Stop it :)

I'd love to get my hands on a raw file of the above pic to see what inherent quality is lurking within.

Thanks David for the reply and advise:) The reason was that I never thought anyone would like to buy my photo, so I only converted them into jpeg, save space! now I learn and find out how silly I am:p From now on, I will develop the file to TIFF as my master copy.

The artefacts above are mainly processing errors.... not JPEG. You're over processing your images.
