    Your TIFF file was processed using Adobe Lightroom from a camera original .ARW (Sony raw) file. Lightroom does have the capacity to upscale the image and that's likely where the resolution increase comes from. The camera original was 4240 x 2832.

    Are any of these photos composites? If I take a photo of you at 1000X1000 and one of your dog (1000X1000), open them both up in Photoshop and put them together in a new document of 2000X1000 without any loss of quality. That would be one way of increasing size, but you should know if they were composites, which you did not mention. (Similarly did he perhaps add some extra "sky" in the background over your head to give a better composition if he had shot it too tight?)

    "I didn't notice any change in the quality," you wrote. And that's one reason he sent you down-sized images.

    Is the reason that you weren't happy with the quality just the resolution? This one to me seems like it might have been better shot tighter and/or framed differently, but everyone has their own style and sometimes with events you can't always get the best vantage point. Maybe the res isn't really the issue or the only issue.

    First off, the image looks about as one might expect being taken at ISO 6400 - some visible noise. I have an older camera with about the same resolution and I would see that amount of noise at ISO 1600. However, the images usually print out very good at 8"x10". I find the solution is to just not look at the images zoomed in 1:1 on the screen unless actually in the process of manipulating the image. Joe noted this TIFF file was processed and exported in Lightroom using the Sony RAW file so that would make the original a full resolution image.

    With the lens used it looks like it was shot at or close to wide open with a lens that still gives some depth of field - so a fair amount is still in acceptable focus, and of course the photographer wanted a high enough shutter speed (in this case 1/200th) to stop motion of the presenter; hence the high ISO.

    It looks like there were lights for video. In this particular image the people in the audience are closer to those lights and are well lit up, while the presenter is of course receiving less light being farther away. A difficult lighting situation, and it looks like the photographer struck a balance.

    I have supplied TIFF files to customers without doing anything to the images other than exporting to the TIFF format (where one can specify the image size) as the customer is then going to manipulate for use in their marketing materials. However, for most event photos I do some basic post processing - depending on the stated final use for the images - and supply those to the customer (this may be in images for initial review, then final in both small size for web and large size for print or the prints themselves).

    Thanks all for the answers -
    clickAddict - it's not composition as you can see in the sample photo I provided - it is one whole photo.

    vintagesnaps - it is definitely not only the resolution - I think it is poor quality in general, if you zoom just a bit closer on the speaker you can see she is very grainy - I think more light should have been applied (he did not use flash, in this case maybe he should) - these are conference photos, and past photos I had speakers looked very clear even when zooming in.
    It's just that resolution is a "hard" metric, so it's easier for me to start with that.

    dave442 - nice analisys and you are correct about the lighting that was present in the back. But I think in the balance of things - the speaker should look better, since the audience is not really the focus point - not really worth it focusing on them and sacrifice the quality of how the speaker looks.
