  1. <p>Just for clarity, I thought I'd explain my understanding of this issue as there is the possibility of some confusion on this issue.<br> So all my figures below are relating to files from a Canon 5d mark iii<br> When we talk about the size of a Jpg file there are two Mb figures, the open file, and the closed file with compression. So the original full Raw Canon file is 5760 px X 3840 px, this as an open file is a multiple of the two pixel dimensions, so when open in photoshop is a 63.3Mb file.<br> I then save this as a Jpg maintaining the 5760 x 3840 pixels at a compression setting of 11 in photoshop [ I do this as if I open a jpg that is 8Mb as a closed file, then re-save it at 12 it will close as a larger file size than it started at, but 11 seems to keep the file size the same], the file size will typically be between 8Mb and 16Mb, this depends on how much detail is in the image, so tree foliage and grass will compress less successfully [16Mb] than say a white button on a white cloth [8Mb].<br> If i do as your photographer has and downsize the file to 3500px on the long side it will become 2333 on the short, giving me an open file of 23.4Mb. If I use my same save quality of 11 my closed compressed file becomes from about 3Mb to about 6Mb, again depending on detail. So this would tally with the file sizes you have, which would tell me the files have been saved at a high quality, low compression, for those pixel dimensions.<br> I haven't at any point given a dpi value as this can be set in photoshop to whatever figure you wish to put in and doesn't affect the file size or quality one way or the other, however if I have a file that has a dpi value set and then change the figure in photoshop, photoshop will by default resample the image making it larger or smaller depending on the dpi I set, however if I un-tick the resample box the file size will stay exactly the same, both open and closed regardless of the dpi value I enter.<br> My experience almost no one ever understands this, the number of times I've had people in the industry tell me the file is only 150 dpi and too small, so rather than explain it, I've changed the file to 300 without resampling therefore sending them back the exact same file, same dimension, same quality but with the box saying 300 instead of 150, and they're happy.<br> Don't send clients tiff files unless they want to make lot's of lossless changes to them, a jpg is much smaller, printable unlike a tiff, and easier for most people to handle on there computer, there is no quality difference in first generation tiffs and Jpgs made from the same raw file.<br> As a wet print is usually made on paper requiring a resolution of 240dpi your 3500 pixel file will print up to 14.5 inches on the long side without loss of quality, I think you could go bigger on an inkjet as they mostly work at 150dpi [although I don't claim to be an expert on inject, but it's what I was told] without a discernible loss of quality.</p>
  2. <p>With regards my earlier post, these are the thumbs I mentioned. All one camera and shown in the time sequence they where shot in. These were all acceptably sharp, not that I always get as many that work, but I would always expect to have a few to choose from.</p><div></div>
  3. Thank you Marc, I'm genuinely flattered coming from yourself. With most all my aisle shots, including from that wedding I do have shots taken in a portrait orientation showing the dress full length. That particular sequence had about 8 usable shots and I changed the orientation a couple of times mid sequence. I tend to be in one shot mode and often walk backwards shooting in my mid stride and try to minimise my movement as I trip,the shutter. I find the focus to be more accurate this way than my standing in the one spot shooting as the couple approach even in servo mode. When I next get to the computer I'll post some thumbs of the sequence. Having said all this, it's a little like us all telling Ralph how he should dress and have his hair cut, what works for me or anyone else is not necessarily going to suit him. None of the advise being given is wrong, but it is coming from a variety of philosophies, all of them legitimate.
  4. <p>Just to offer an alternative to flash in any form, these are both without flash. The B&W image was taken with a 70-200/4 @ 80th f4 1600iso. The second is a December wedding taken with 85/1.2 @ 80th f2.5 2500iso<br> I'm sure they won't be to everyones taste, but personally I find it more flattering, but also it's how the couple will remember the moment.<br> If you use flash it usually floods the area with light and transforms the space into something it wasn't.<br> I always think it's like going to a nice restaurant with candlelit tables, if you throw a floodlight across the room the ambiance is lost.</p> <div></div>
  5. <p>I don't normally post here although I do look in from time to time. I don't post because I don't share the general aesthetic of the forum, which seems to be very flash oriented and not something I personally like, but I was intrigued by your approach as I don't think I've read of anyone going to a wedding with such an arsenal of equipment as you did.<br> I have to say, I think the area you most need to address is basic composition, you don't seem to me to have paid any attention to foreground or background in any of the shots you've posted so far. Most of your images include details creeping into the frame which could either have been excluded, or included with a compositional balance. Even your set shot of the bridesmaids has a bit of plant, a bit of wall, and a bit of an arch, it's just sloppy.<br> I know this will sound very harsh, and I'm sorry to be mean, but you set your self up with such a seemingly encyclopaedic knowledge of gadgetry that I really thought you'd produce something quite strong. Your response to criticism has been to retreat into yet more technical jargon, but that's not the fundamental problem I'm afraid.</p>
