645D IQ Questions

Just started shooting with my 645D. Is the color you get with this sensor different from the smaller format cams? Some of the grass color in the 645D looked diferent from what I thought it should look like.

How do you find the HDR shots with this cam? Any different techniques than you use on smaller format?


Thanks

The tonality is different. That includes color, shadows, and contrast of the images. If you change the different image tone settings, I would recommend the "natural" setting for the best color match. When shooting in RAW you can change this later easily. I used the HDR mode once or twice, the pictures looked alright. You can change the intensity too, but it is only available in JPEG mode.
I prefer doing a HDR by myself. Then I can shoot in RAW and process the pictures with a HDR programm. The results are much better.

I use the mirror lockup function with the 3 second remote timer all the time. Very useful feature.
I also use the infrared filter mode sometimes, which is available in the monochrome setting. Never saw such a filter on any camera before. The results can be quite outstanding.

The color on the 645D is different from smaller cameras. In fact, it is really good. A review of the 645D stated the color preproduction is very high, better then most cameras on the market. I tend to agree.

I agree, the 645D has the best (and most accurate) color of any camera I've used.

It is just a software filter, but the effect is really cool nonetheless. Use it in high contrast situations, with strong light-shadow contrasts, to get the best results.

The 645D has great color in daylight. Not so great color in tungsten. And is totally baffled by mixed light. IMHO............ And the ISO ratings are for daylight and are incorrect for tungsten (open up for tungsten).

You know you can set how much WB correction you would like for tungsten in the menus. I think the exposure is a factor of the scene contrast, rather than color temperature--ISO is not a function of color temperature, but s/n. I find the 645D tends to underexpose in flat lighting.

I have not had the same experience with mixed lighting. The 645D does better then other cameras I have had.

ISO ratings for daylight and not for tungsten? Do you mean the metering? And before, or after WB correction?

makes a big difference what raw converter you use but if you use PDCU instead of 3rd party converters you will get more accurate looking colors.. but honestly even Nikon/Canon can produce very similar looking results using their supplied software..

I mean that if you take your own handheld meter and establish ISO in daylight and then you light a scene with tungsten, lit to the same indicated values on your handheld meter, the scene will be underexposed, since the sensors are manufactured for daylight and tungsten is a compromise.

I thought WB correction was just a function for JPG shooters. Perhaps i missed something in the manual regarding how WB correction affects RAW shooting ?

WB in RAW just tells the raw conversion software what WB to set by default. You can then change it all you want.
